[REF] Startup script speed tweaks

Hi guys,
UPDATE: Over time, I've modified some of these values in my SpeedMod kernel. The values here may not be the best ones.
NOTE: These tweaks are now included in kernels based on sztupy's Universal Lagfix, for example:
http://forum.xda-developers.com/showthread.php?t=822756
But they must be manually activated from the recovery menu.
I've been using Linux kernel tweaks in a startup script to make the phone smoother.
With these tweaks, the phone is quite smooth and fast even without using the filesystem lagfixes.
These settings are only useful for you if you know how to create and modify a startup script. I use the old playlogos hack myself, but I'm sure there are many new ways to do it now.
Code:
# Tweak cfq io scheduler
for i in $(ls -1 /sys/block/stl*) $(ls -1 /sys/block/mmc*) $(ls -1 /sys/block/bml*) $(ls -1 /sys/block/tfsr*)
do echo "0" > $i/queue/rotational
echo "1" > $i/queue/iosched/low_latency
echo "1" > $i/queue/iosched/back_seek_penalty
echo "1000000000" > $i/queue/iosched/back_seek_max
echo "3" > $i/queue/iosched/slice_idle
done
# Remount all partitions with noatime
for k in $(busybox mount | grep relatime | cut -d " " -f3)
do
sync
busybox mount -o remount,noatime $k
done
# Tweak kernel VM management
echo "0" > /proc/sys/vm/swappiness
#echo "10" > /proc/sys/vm/dirty_ratio
#echo "4096" > /proc/sys/vm/min_free_kbytes
# Tweak kernel scheduler, less aggressive settings
echo "18000000" > /proc/sys/kernel/sched_latency_ns
echo "3000000" > /proc/sys/kernel/sched_wakeup_granularity_ns
echo "1500000" > /proc/sys/kernel/sched_min_granularity_ns
# Misc tweaks for battery life
echo "2000" > /proc/sys/vm/dirty_writeback_centisecs
echo "1000" > /proc/sys/vm/dirty_expire_centisecs
EDIT: Explanations:
# Remount all partitions with noatime
atime is a setting where the filesystem updates the access time of a file. This creates a write-after-every-read which slows things down. By default all partitions are mounted with relatime, which is an optimized version of atime. noatime is the fastest, and afaik we don't need atime.
# Tweak cfq io scheduler
Tweaked settings of the disk io scheduler more for flash memory. Defaults are optimized for spinning harddisks. Lowered the idle wait, re-enable the low latency mode of cfq, removed the penalty for back-seeks and explicitly tell the kernel the storage is not a spinning disk.
# Tweak kernel VM management
Set tendency of kernel to swap to minimum, since we don't use swap anyway.
Lower the amount of unwritten write cache to reduce lags when a huge write is required.
Increase tendency of kernel to keep block-cache to help with slower RFS filesystem.
Increase minimum free memory, in theory this should make the kernel less likely to suddenly run out of memory.
# Tweak kernel scheduler
Make the task scheduler more 'fair' when multiple tasks are running. This has a huge effect on UI and App responsiveness. These values (less aggressive settings) are 20% of the Linux defaults, and about half of the Android defaults.
# Miscellaneous tweaks
Increase the write flush timeouts to save some battery life.
___________________________________
EDIT: How to create/use a startup script:
You need root and busybox for this.
This procedure is adapted from the old OCLF which used this method to create a startup script in /system/userinit.sh
Check if the file /system/userinit.sh exists. If it does, u should just edit that file as the startup script and DO NOT do the procedure below.
Here's how to do it manually. Do this only if some other lagfix/patch has not already done the playlogos hack, otherwise u might overwrite the other script!
Create the startup script on your PC. Use adb to push it to /sdcard/userinit.sh
adb push userinit.sh /sdcard/userinit.sh
On your PC, create a file called playlogos1 with this content:
#!/system/bin/sh
sh /data/userinit.sh
playlogosnow
Use adb to push the playlogos1 file to /sdcard/playlogos1
adb push playlogos1 /sdcard/playlogos1
Now use adb shell, su and do this:
busybox mount -o remount,rw /system;
busybox cp /sdcard/userinit.sh /data/userinit.sh;
busybox mv /system/bin/playlogos1 /system/bin/playlogosnow;
busybox cp /sdcard/playlogos1 /system/bin/playlogos1;
chmod 755 /system/bin/playlogos1;
chmod 755 /data/userinit.sh;
The startup script will be /data/userinit.sh
The reason I put the startup script in /data is so that if you mess up the startup script and get stuck during boot, you can do a "clear data" from recovery, and the startup script will be erased.

Could you explain what this actually does for the non linux savvy, also maybe you could make a script/app for this so everyone else can try it ?

Hey supercurio! Great job on Voodoo, I am particularly keen on the Sharpness, Video and future Sound fixes. I think its very cool that you found out how to modify the sharpness (S-AMOLED's PenTile matrix software algorithms?).
Edited the starting post with explanations. Most of them should be documented somewhere in the Linux sources / documents.
I've been using them for a while, tweaking values here n there. I think I've finally reached a stage where I'm confident enough to recommend them to others to try. There could be more optimum values with further testing, but these work well for me with Froyo.

Yeah thank you so much for taking the time and sharing, i'll integrate them after a bit of testing
About the sharpness filter yes this is the main difference between S-AMOLED and AMOLED panel wise.
It's a hardware sharpness filter which is here to fight the fuzziness introduced by the pentile pattern but.. they overdid it a bit.
The "perfect" values are of course closer than the one with the same radius that the one of the blur introduced itself with the pixel pattern.
I feel it can maybe be improved a hair
I'll soon publish a version that allow write to the mDNIe register so you'll be able to play *live* with it too

Nice, could these be modified post-startup? like I go adb and copy paste some of them for testing?
I've tested setprop windowsmgr.max_events_per_sec 68, no difference. Set it to
setprop windowsmgr.max_events_per_sec 10 and still, no difference.

I don't think the setprop values can be modified post-startup. You can check if the value was modified by doing a getprop. (The default value for that prop is 55.)
The rest of them can be modified post-startup though.

Excuse my noobiness on Android, I would like an explanation on this command:

On my GNU/Linux system I've set vm.swappiness to 10, because I've got plenty MiB of RAM and I don't want my system to swap a lot. Is this swappiness the same as Linux? Because that would mean having the system to use more RAM, and since we don't have much of that available by default, I'm just surprised you didn't set a higher value. (I'm not saying you don't know what you're doing, I just want to learn how it works!)
By the way, this script is going to be a must-have, I think you've put an excellent effort on i9000 Android development! Thanks for sharing!

The aosp windowmanager (android framework) ignores values <35. (Samsung could have changed something here, but that is very unlikely).
That value does not affect the framerate, but how many touch events are reported to the apps; this saves some cpu if the user keeps touching the screen.

Yes, i tried on Eclair to set it to 56fps (real fps is 55.5555555555555) but touch scrolling were not smoother.
I hope it can be improved in some way!

Thanks for the info. Looks like default settings are best unless we can actually change the refresh rate.

I'm interested in doing this but I'm not sure where should I put the file. I checked playlogos1 from /system/bin but it's a binary file.. Tried to find playlogos hack on the forum but can't really find anything...

i have a jpm with voodoo, and i have copy this code into /voodoo/scripts/init.sh
just simplely add to the end of it, of course, before the last line.
the system reboot is ok, but i havent see the effects yet.

btw, "ls -1 /sys/block/mmc*" in adb give us:
Code:
ls -1 /sys/block/mmc*
-1: No such file or directory
/sys/block/mmcblk0
/sys/block/mmcblk1
so, "-1" key is useless

init.d performance startup script

I've adapted the original performance tweaks by 'hardcore' @ XDA for my overclocked/undervolted Galaxy Tab. The tweaked values are pretty much the same as the ones recommended by the original poster, but my simple init.d/ script allows me to log default system values when pushing new values, which is useful for debugging. The script also contains comments to describe the role of each setting. Note that if you don't have init.d/ support in your kernel / initramfs, you can still run the script manually at each system start (use an app like GScript).
Code:
#!/system/bin/sh

# Note that "run-parts" support (for init.d/ scripts) is normally provided by custom a initramfs,
# which should bundle busybox in /sbin/. The /sbin/run-parts.sh script should take care of
# running init scripts (by calling /sbin/runparts), and it should subsequently trigger
# the device startup (using "setprop filesystem.ready 1", or similar).

Thanks for this Daniel - since I know absolutely nothing about anything Android, all I can say is that I have 2 questions
1 - Would this script be any benefit to someone running a custom ROM (Overcome 1.1.3 in my case) and a custom kernel (Richard Trip's 1.4gHz EXT4)? I ask because I don't know if these guys have already including these tweaks or not... but maybe I should ask them instead...
2 - Is there any way you could put that script - in its most efficient, non-debugging form - in to a script file that us speed-freaks can just toss in to init.d and reboot?
Please do forgive me for any newbishness I have displayed here.

So should I put this script in /system/etc/init.d/ ?
UPDATE: Ok, I've done the script(without extension at the back of the file name) and put it in ~/init.d/, it runs well. I comment out the remount and logging function tho Tested it on some games that required load time like gangstar which lags alot previously, now just dnt have any lag time in it! Thanks!
Anyway, im running Overcome rom with richard's kernel, other than voltage script, i saw 2 more script that does the following:
10fixsh does:
"#!/system/bin/sh
busybox mount -o remount,rw /
find /sbin -maxdepth 1 -type l -exec rm {} \;
busybox mount -o remount,ro /
"
99done does:
"#!/system/bin/sh
sync;
setprop mcr.filesystem.ready 1;
"
So I just add your script as userinit since they do not have conflicting calls

Personally thinks that similar tweaks should be included in custom kernels so that those who wish to do more extreme settings can go with it while those who just wants increased performance as it is can still have the boost provided by such init script.

still need more time to test, after some verification, none of the "/proc/sys/kernel" setting works with any of the kernel i'm using. thats y i need more time to rectify..
used richard's kernel and overcome kernel, both dont do anything now..perhaps wrong command in the script? Cause run-parts.sh does specify where to run script, and init.d does have 2 script in there that runs. So i'll need more time to make sure it works now..
Dont need to have .sh as extension, just a name for your script like the other 2 script that i posted in previous reply. And I did not copy the whole script to run, as the script seems questionable in some part..

The init.rc file gets extracted from the initramfs ramdisc (packaged inside the zImage kernel) at each device startup. Changing this file's content is not a good idea. Regards, Dan

Yes, the filename of the startup script must start with "S_" and must not end with ".sh". This is standard Linux stuff.

Normally Busybox should be installed properly in "/sbin/" by your kernel provider, you shouldn't have to touch this folder.

The "mcr.filesystem.ready" is only relevant if the "init.rc" file in the kernel zImage's initramfs ramdisc responds to a change to the "mcr.filesystem.ready" property (for example, when its value changes from 0 to 1). This is typically used to start the device normally, after *all* of the "/system/etc/init.d/" startup scripts have been executed.
The line of code "setprop mcr.filesystem.ready 1" is therefore typically included in "/sbin/runparts.sh", not in one of the "S_startup_scripts" (as this may trigger the device normal startup prematurely).
It really depends on your kernel, so it should be documented by your kernel provider.

Yes, the filename of the startup script must start with "S_" and must not end with ".sh". This is standard Linux stuff.

Great! thanks for clarifying! Sadly none of the kernel provider states any info on such matter. Will try your script again, as previously running thru gscript not all command works..

Copied your script 100%, put it in init.d with chmod 755, named it S_userinit, doesnt run..i double checked by cat value that I stated to change in the script.
Help? It obviously runs the UV script in init.d tho.
EDIT: Got it to work by editing the UV script, now settings are in! Great! Time to test anyway, nodiratime is not needed, noatime already has it

So how can I use this script - I want to
Hi, Just connected to my galaxy tab running froyo, and went looking in my filesystem for the init.d folder and yeah there isn't one
do i create one? where? and what permissions?
I try to keep this brief and not waste too much of your time.
many thanks for the script
Ttime & effort ++

you will need a kernel that support init script, after that, /etc/init.d(or /system/etc/init.d) will be created

Don't suppose you could post a copy of your trimmed & tweaked version of Daniel's script for us to use?
Cuz I, for example, have no idea what's useful in the original script, and what's not useful. But I at least know how to edit the UV script, heh.

NOTE: If you change any settings in uv app, u'll revert S_volt_scheduler to ONLY UV settings, so It's recommended to edit your UV setting on this file instead of using uv app from now on if you wants to keep your other settings

hey fastcx, i copied and pasted your script in the UV scheduler file in init.d but it seems that it's not working as the values don't apply. any ideas why?

[Tweak] Boost RAM Management - get more free RAM! // [23.03.2011] Fixed Permissions.

Memory Tweak - get more free RAM to use for apps and less lag.
// This was first intended for other ROM chefs, so they can include this tweak in their ROMs. I'm aware that there are apps which can do this. But it's the idea to have it included automatically, so you don't have to annoy your users
However, this is also for normal users. Those just flash the CWM Package thunderteaser made here. Thanks for this.
I made a script which boosts the RAM Management significantly.
You can use this in any ROM - those values have been created from my mind and were being tested for several days in heavy use.
IMHO, it's the perfect combination of RAM Management.
HOW TO IMPLEMENT IT INTO YOUR ROM
Just make a new bash script and place the following code into it.
NOTE: bash files created on Windows don't work. Create them with a UNIX like Linux (Ubuntu, Fedora, whatever) or Mac OS X.
Place the script in /system/etc/init.d so it gets automatically executed at every startup. You have to make this because init.rc (in root dir /) gets executed first and will also set the RAM Management (minfree) on his own.
UPDATE - 20.03.2011
Supercurio said, there is support for init.d in his Voodoo injected kernel for JV1 Gingerbread.
This means, the script is fully working and the Gingerbread JV1 memory leaks are fixed when using those values.
This also means, my current ROM v10.0 Beta 3 already has the Memory Hack integrated.
Code:
#!/system/bin/sh
# DarkyROM 2011 - Joël Staub (darkyy)
# This will stabilize the memory leaks in Gingerbread and other ROMs.
# Adjusting Memory Settings
# The values in MB: 10, 16, 24, 68, 76, 92
if [ -e /sys/module/lowmemorykiller/parameters/minfree ]; then
echo "Modifying minfree parameters"
echo "2560,4096,6144,17408,19456,23552" > /sys/module/lowmemorykiller/parameters/minfree
else
echo "minfree not found"
fi
Permissions
You may want to adjust the permissions of the script when it's on your phone.
You can do it with ADB.
First, connect to your phone.
Code:
adb shell
Get root access.
Code:
su
Set the permissions.
Code:
chmod 777 /system/etc/init.d/ramtweak
Code:
chown root:root /system/etc/init.d/ramtweak
When you're a ROM chef, you can include those permissions either with update(r)-script or with a bash file.
Thanks to zacharias.maladroit for the hint with the permissions.

You just make a new file on your COMPUTER.
Or it would even work on your SGS (but I'm writing now for the Computer).
Example:
Let's say, you're on Windows - create a NEW text file and remove the .txt extension (you need to have this option activated in the explorer settings).
You can leave it to no extension or just make it end on .sh
You got a file called randomname.sh now.
Now to make it easy, just copy this file to the C: drive in NO subfolder.
Now just ADB push this file to your SGS into:
Code:
adb push /randomname.sh /system/etc/init.d
Or just copy the .sh file to your SGS via USB Storage mount and copy it to the directory with Root Explorer or Super Manager.
Yes, this should work with every kernel (Android 2.2.1) here.

Thanks for doing this testing to find good settings. Forgive me if I'm misinformed, but is there anything particularly innovative about new minfree settings? I do appreciate your testing and finding ones that work well for you.

have a good rest, Darkyy !
thanks for this script
so you noticed improved interactivity with "apps and less lag" ?
gotta try this with CM7
FYI:
the defaults of the CM7 kernel are:
Code:
cat /sys/module/lowmemorykiller/parameters/minfree
2048,3072,4096,6144,7168,8192
edit2:
make sure that you get the right permissions for the file on the phone afterwards
say:
Code:
chmod 750 /system/etc/init.d/99rambooster
chown root:shell /system/etc/init.d/99rambooster

thanks for explanation ! I have done what you say and rebooted my phone after that. I renamed the file to init.d after placing it into the /system/etc/ directory and setted the défault permissions for this file rwxrwxrwx (or something like that)
But how I find if I have the hack succesfuly installed ?

Not innovative - this is nothing new.
It's just that many ROM devs aren't aware of this and I thought I could share my script.

Gah this is such a retarded suggestion. Darky your SGS ROM is really nice and I'm currently running it, but please think about things like this before you post them.
The SGS has, comparatively, RAM out the wazoo. Why do we want more of it sitting idle and unused? RAM is there to be used, not sit there looking unused and pretty like a virgin at an eastern european slave auction in a free -m command. Twatting about with this setting on behalf of the Android Low Memory Killer is essentially like telling the ROM you have less RAM than you actually do since it will always endeavour to keep that much RAM -free- as in -unused- by the GUI itself as well as Android apps.

seriously: read what comes after the 1st ,2nd and 3rd post - or the first 1-3 (or 5 sites) if it's a larger topic
you'll see that you need to change the permissions & owner
you do that via logging in via adb, becoming root (su)
and navigating to /system/etc/init.d/
or do it explicitly from the folder where you are - like I posted

[BASH4.1+][SCRIPT HELPER][LIBRARY]semi-native function library

Hello XDA users, deciding to post this here because i figured it could get some use/i could get some feedback
(Placing it in general because i honestly dont think it could work anywhere else)
Basicly over the past few months ive been taking my multiple script for android, & rewriting/compressing into 1 library
& adding features/functionality that i consider useful. This script has never touched a PC, & only been written on android
(BTEP & DroidEdit Pro), & is designed to:
A.) Extend the basic terminals functionality.
B.) Extend customized scripts, & making scripting semi-easier.
C.) Offer multi-device compatibility while keeping origional functionality.
The script is capable of determining all critical variables on initialization, from
partitions (both mount name, & partition number can be easily obtained), OS/ANDROID version/type
Execution mode (source/exec), Autodetect instigator (Eg: boot, script, shell, etc.) If present, Execution level,
Etc, seamlessly before scripts execution, & modify its own execution accordingly.
The script can be used in a similar method to busybox (Eg, can be called directly, or through symlink
(Symbolic link) using functions name, & allows adding multiple switches at runtime which can totaly
Customize execution without touching a configuration (yes, it does support configurations).
Or for script/shell, can be sourced for max performance & increased functionality.
This script is designed to be as native as possible, & only requires busybox/toolbox, & bash (4.1+)
(Systems default/sh) is not sufficient.
Readme (1/2, Read 2nd post):
Code:
----------------------------------------------------------------------------------------------------
Table of contents:
1.) Basic information
2.) Installation
3.) Usage
3a.) Basic commandline switches
4.) Included functions & definitions (Execution)
4a.) Included functions & definitions (Source only)
##########################################################################################################
Basic Information 1.
SuperBox is a multi-call, multi-execution function library (think busybox with bash & sourcing),
built on ANDROID, For ANDROID, Designed to increase script efficiency, & offer "unstandard"
multi-device functionality, & some functionality considered "missing" from ANDROID/Linux by default.
##########################################################################################################
Installation 2.
Superbox is designed to be easy to install/use, and requires very few steps/dependancies to install.
Before installing, please check this small list of prerequisites & insure you have the required
dependancies to ensure correct installation, the following are required:
a.) BASH 4.x (4.0+) installed & linked to '/system/bin' & '/system/xbin', Systems default is not
sufficient & cannot support SuperBox in all needed areas.
b.) BusyBox 1.18+ (tested on v1.19.4), Please ensure toolbox is also fully installed.
c.) Device must be rooted & running S-off (insecure kernel, read kernel documentation)
This part can be bypassed if installing through recovery. Some features will be limited.
d.) SuperBox is a terminal/script expansion toolkit, as such, a terminal emulator (Such as BTEP aka:
Better Terminal Emulator Pro, or similar) is recommended for optimal usage.
if your device can meet the above requirements, you are ready to install.
To install, simply move the downloaded script (superbox, or superbox.txt) to either '/system/bin', or
'/system/xbin', if the downloaded file has an extension, remove it.
Set permissions to 755 (rwxr-xr-x), Once complete, open your preferred terminal, & type 'su -c bash'
once in bash, type 'superbox' (or whatever you named the script), or 'superbox --info', if the operation
succeeded without error, you can begin full installation, Simply type either:
'superbox --install', or 'superbox --install <FUNCTION> to fully install, or install specific function.
See section 3a (Basic commandline switches) for full list of available switches, or section 4
(Included functions) for list of executable functions.
##########################################################################################################
Usage: 3.
SuperBox allows multiple methods of execution, & preferred method is left completely up to the user.
Sourcing:
SuperBox can be sourced either in terminal, or script, using something similar to
'. superbox', or '. ./superbox' if kept in unstandard path. if sourcing in terminal & script appears
to continue to execute, Try adding '--noboot' switch (see section 3a).
Script allows extra functionality not typically available in execution mode.
Execution:
this is the most typical use for superbox, & as easy as typing 'superbox <function>' or '<function>'
when fully installed. For list of all available functions, use 'superbox --list' to generate full list
of available applets, Please note that when using '--list' or even app count when using '--info' is
only listing execution type applets, Source functions are NOT included in this list.
----------------------------------------------------------------------------------------------------------
Basic commandline switches 3a.
SuperBox allows adding additional variables through commandline to modify per-execution variables,
Without editing a configuration, or worrying about recurrent changes. These variables effect a wide
range of scripts functions, & are available in 2 levels,
1.) SuperBox switches:
These switches effect the script as a whole, & are listed/added by the double-hyphon prefix ('--')
These are the only switches listed in this readme, for individual functions switches, please use
'superbox <function> --help' or '<function> --help' if fully installed.
1.) Function switches:
These switches only effect the function being processed, & are listed by a single-hyphon ("-"),
These are not available in all functions. Function switches should be used after superbox switches.
SuperBox switches:
The following MUST be passed as MODE & must be called directly from SuperBox, Eg:
'superbox --<MODE>', Not capable of being passed as variable.
install | Usage: '--install <FUNCTION> --installto={PATH}', Generates symbolic link for FUNCTION in
| PATH, if no FUNCTION specified, installs all, if no path, Default is used.
remove | Usage: '--remove <FUNCTION>', Opposite of above, Removes link for specified function.
| Scans system to find symbolic link, use '--full' switch to scan full recursive.
chkbb | Checks install status of busybox, & capable of generating missing links, use '--fix' to
| auto repair any/all missing links.
version | Displays installed SuperBox's version.
list | Lists all included execution-capable functions included in current version.
The following are to be used after mode (function listing), Eg: 'superbox <MODE> --<SWITCH>' or
'<MODE> --<SWITCH> when fully installed.
debug | Forces debugging on script (uses 'set -x' command), applies to script as a whole.
bb/tb | Pre-determines which busybox/toolbox versions to use, Must be used as '--bb=/path/to/file'
| or '--bb/path/to/file', Specifying invalid input will restore defaults when executing.
color | Default Colors for modes allowing color. sets color based on position in strings, Eg:
| '012345678' (upto 9 characters) where: 0=Error, 1=Note/Highlight, 2=Note2, 3=Normal,
| 4=File, 5=Path, 6=Link, 7=Background, 8=border, use pound (#) in place of unused spacing.
| for full listing of colors, Please see 'manfunc Col'
nocolor | Overrides above switch, & disables color in all segments.
installto | Modify install location for current component. (Used as '--installto={PATH}')
| MUST be used after install mode (Effects most file-based sections).
file | Usage: '--file="{/FULL/PATH/TO/FILE}"', used to set file path/name for specific segments
| Only effects segments where single-file processing is key.
local | Usage: '--local=\"{PATH\"', Assign path to use as local directory.
home | Usage: '--home=\"{PATH\"', Assign path to use as home directory, Use above over this.
time | Usage: "--time='{FORMAT}'", Specify time format (see '--timef'), (used for Lecho, etc.).
timefull | Usage: "--timef='{FORMAT}'", Specify full time/date format for script. %Y=4-digit year,
| %m=2-digit month, %d=2-digit day, %H=2-digit hr (24hr), %l=hour (12hr), %M=2-digit min,
| %S=2-digit seconds, %h=print month, %l=hour (12hr), %a=3-char day, %c=full (default).

*NOTE
some functions might not be considered 'main stream' or correct, but through trial & error, seem to work
Best with the chosen method.
Some functions are a WiP, might not be functioning correctly.
If you experience an issue, or have a suggestion, Please let me know.
**EDIT**
Updated, most functions should work correctly now.

Readme (2/2):
Code:
Included Functions (Execution) 4.
alignapk <file>
> Automaticly align <file> if specified, or all installed apks otherwise. can specify specific apk, or
simply apk name if apk is installed. Ex: 'alignapk systemui' is equivalent to
'alignapk /system/app/SystemUI.apk", extension (apk) is not needed, if path is specified, must be case
specific, otherwise alignapk will attempt to process case insensitive. Script will generate a SQL
database by default, but can specify text-based database with customized settings (See default config)
bam <Process1> <Process2>...
> kill any running processes matching specified input. Partial matches are supported, Eg:
'bam media' can kill 'android.process.media', aswell as any/all packagenames including 'media'
baseext <FILE> <MODE>
> echos the base extension of <FILE> if no MODE specified, or filename without extension if <MODE> is 1.
Anything else will display File with 'MODE' as extension, Eg: 'baseext ex ample' will return ex.ample
bar <var1> <var2> <var3>..
> displays accurate progress bar on screen, with the default terminal width as overall length.
Supports multiple customizable parameters. Only supports duration & strict percentage in current
build, More uses will be added in future builds (Eg: watch process, count, etc). Supported switches:
-t | Specify total time to run the bar, Usage: '-t=' where '' is scripts duration.
-p | Specify strict percentage to display (dont count) Eg: '-p60' will display 60% progress & quit.
-e | Specify displayed text when running the bar, multiline supported, can use script variables.
-d | Specify ASCII character to use for generating progress bar. default is '='.
-w | Override default width to use when processing bar, default is terminals width.
-n | Show progress Percentage (%) rather then progress bar (-b works as the oppisite)
-s | Display incrementing progress bar (jumps by ~1%) rather then the per-increment jump.
-k | same as '-s', but shows percentage at end of bar. (will increase exec time)
basepath <PATH>
> echos the base path or mount point (closest to rootfs) of <PATH>
byte <BYTES>
> Automagicly calculates Bytes(B)/kilobytes (Kb)/Megabytes (Mb)/Gigabytes (Gb) based on
on given Number in 'BYTES' on the *1024 principle, Eg: 'byte 1024 = 1Kb', Supports decimal places,
& maximum decimal points can be modified by 'MaxDec=' variable. Uses rounding to strip access.
Using '0' as 2nd variable will remove non-numaric characters from return (Eg: 'Kb/Mb/Gb/etc.).
Using '1' as 2nd variable will seperate non-numaric & numaric characters (Eg: '1Kb' would b '1 Kb').
calc <VAL EXPR VAL> or echo "VAL EXPR VAL"|calc
> similar basic functionality to 'bc', mini calculator script using 'awk' & 'printf', Supports Piping,
(function|function), float integers (decimals) & multiple types of arithmatic.
chrg_type <MODE>
> Quickly determines where the device is currently getting power from. Following modes are supported:
0 = Quiet output, returns 0-2 for Battery/AC/USB respectively.
1 = similar to '0', but displays code Aswell as return code.
2 = displays source (Eg: Battery/AC/USB), all other modes will simply display string.
chkdir <PATH> <PERM> <OWNER.GROUP>
> Checks existance of <PATH>, calls 'mkdir -p' if not exist, & sets permissions <PERM>
(numaric) when creating, & sets owner/group if spedified.
chksize <MOUNT> <CHECK> <ECHO>
> Checks if <MOUNT> has <CHECK> mb free (good for checking before extracting/installing). Returns 1/0
accordingly. set <ECHO> to 0 to use errorcode & disable echoing to STDOUT (if statment, (echo $?))
chkstate <INPUT> <EXEC_CMD>
> Determines if <INPUT> is available for script use, able to detect functions, aliases, links, binaries,
files, Variables, etc. specify <EXEC_CMD> to exwcute <INPUT> if detected. (binaries/functions/etc.)
Col <STRING> <MODE> or Col <STRING>
> Used for colored text Replace 'Col' with either: Bla(ck), Blu(e), Red, Gre(en), Whi(te), Mag(enta),
Cya(n), Yel(low). Ex: 'Bla "sample text" 1', Available modes are: 1=Bold, 2=Underline, 3=colorfill
(switches background/text), 4=no newline, 5=bold (no newline), 6=underline (no newline).
columns <MODE>"
> prints available columns, Set <MODE> to 1 to print number of lines (height of prompt).
conv <celsius|fahrenheit> <TEMP>, or conv <F> <T> "<STRING>"
> a rather bloated conversion script capable of converting tempuratures, or string to various formats.
-When converting tempuratures, both 'conv c 100', & 'conv 100c' are correct & will output sum
-When converting string, 'F' (From) & 'T' (To) must be specified to begin calculation.
'F' & 'T' can be one of the following: 'a' (ascii) (normal text), 'b' (binary, outputs 8-digit binary
code for each character specified), or 'h' (hexadecimal), when processing from hex, 4th variable
specifies preceeding character(s) to add to each return (default is '\x'), if set to 0, no characters
are added to string, only 2-digit hex is returned, For example: 'conv a h hello' (no 4th variable)
returns '\x68\x65\x6C\x6C\x6F', while 'conv a h hello 0' returns '68656C6C6F'.
divider <LENGTH> or divider -d<CHAR> <LENGTH>
> generates a bar (String of character(s) or CHAR if set), <LENGTH> characters long, if no LENGTH set,
total width of terminal window is used. Use '-d<CHAR> to customize character, Default is pound ('')
Eco <ABCDE> "TEXT"
> Echos <TEXT> with specific atributes, based on <ABCDE>, where: A=Line only [0|1], B=no newline[0|1],
C=(Bold[1], Underline[2], None[0]), D=Text color, E=Background color. Valid colors include:
0 - black, 1 - Red, 2 - Green, 3 - Yellow, 4 - Blue, 5 - Magenta, 6 - Cyan, 7 - White
ex <path/to/file>
> Extract archive to designated path, & even allows recompiling. use '--help' for more information.
exist <INPUT>
> Attempts to detect input & gives return code depending on findings Eg: 3=Dir, 2=Link, 1=File, 0=none.
fdate <INPUT>
> Same usability as 'busybox date -r', Returns modified date of <INPUT> Output can be adjusted
using '--timef' switch.
FixCl
> Returns color to normal, regardless of user-preset defaults.
getblock <MOUNT_NAME>
> Simply echos the block ID of requested point, saves a lot on scripting & allows true multi-device
compatibility. Usage as: 'getblock system'
gnasty <OPTIONS> <PATH>, Or 'gnasty <PATH>'
> Searches for files/paths with names containing invalid characters such as
[+ { ; " \ = ? ~ ( ) < > & * | $], Prints any/all links, includes full path by default. Modes include:
-d - specify directory, used as '-d={PATH}', not needed in most cases.
-m - Max search depth from directory, cannot be less then 1 (default). Usage: '-m' or '-m='.
-i - Display files inode (index number), useful for looping output to irm.
ipath <path>
> Will auto-correct <path> to case-sensitive (if exist) when input does not match case
(case-insensitive path correction through function)
irm [-irRfna] FILE, or 'irm FILE'
> remove (unlink) FILE using inode (index number). used for files/paths with illegal
characters in the name, (Eg: '+ { ; \" \\ = ? ~ ( ) < > & * | $'). The following modes are supported:
-i - Always prompt before removal | -f - Never prompt before removal
-r|-R - Remove file(s)/path recursively | -a - Only use name (no inode, replicating busybox rm)
-n - Ignored, used solely for script use.
is_num <STRING>
> Checks if 'STRING' is numaric (Contains only numbers), Returns 0 if true, 1 otherwise.
Can use '1' as second variable to echo result aswell as return code, eg 'is_num <STR> 1'.
lc "<INPUT>"
> Switches input to all lowercase, supports whitespace/newline, no limitations.
Lecho <MODE> <TEXT> <FILE1> <FILE2>
> Used to pipe text to log (while removing color/string data) & terminal.
If no file specified, Simply replicates echo with log header. Supports the following headers:
1=' : ' (default), 2='[!]' (error), 3=' > ' (note), 4=' ' (continuation).
lperm <PATH|FILE> <MODE>
> Execute user pre-generated configurations (mperm) based on input, can choose to either restore whole
path to configured state, or simply process 1 file from said config.
set <MODE> to 0 to disable recursive loading (dont descend into subdirectories).

(and even adding), Supports 7z, zip, xz, bzip2, gzip, tar, & wim archive types. use '--help' for info
mod <OPTION> <var1> <var2>
> Modifies particular segments of device: Following options are supported:
b | brightness Modifies LCD (Display) brightness NOT supported on some devices.
display | Modify current pixal density, Eccepts numarical value (like lcd.density in build.prop),
Changes are made on the fly, & will reset all open applications, use with caution, can use
'reset' to reload default density from build.prop, Usage: 'mod density <value>'.
mperm <PATH|FILE> <MODE>
> Generate configuration for specified input, recording type, Permissions, Owner & Group, These configs
can then be loaded at any point specified, or ondemand using lperm, Supports the following modes:
0=non-recursive, 1=ignore errors,
myip
Display devices current IP, using nothing but wget, making it the trimmest ip oneliner around :)
ofcourse, internet connection is required.
nocl <STRING>
> Removes color variables from <STRING> to allow recording dato to log.
pinfo <NAME> <MODE>
> Neatly Prints process information for specified <NAME>, Supports the following modes:

pwr <mode>
> Advanced power control, with additional modes, which should work on multiple devices, Available modes:
reboot | reboot device, can use 'reset' aswell with same effect. can use 'hot' as 3rd variable to
perform hot reboot (still performs sync), simply reboots OS without rebooting kernel.

(& even switch again). Sticky/"special" fully supported. Again, 'switch' is easier/cleaner to manage.
remount <MODE> <0|1>
> remounts system & rootfs in specified mode, Second variable in string is unneeded But determines
check state, 1 will use rootfs as check, 0 will use '$System' (default), Use '--help' for more info
rootrw/rootro
> Mounts 'rootfs' as R/W (Read/Write) & R/O (Read/Only) respectively, similar to miniscripts included
in most Roms, With the exception that it utilizes the autodetection available in script, & should
work on any device/rom.
setlength "<STRING>" <POSITION> <LENGTH>
> displays the adjusted value of <STRING>, & should be under <LENGTH>,
autocorrects/centers based on given input, If no length is specified, 'Cw' (Common width) is used,

> Generates sha512/sha256 encoded hash from string, similar to 'md5' function.
showperm <PERM_STRING>
> Displays permissions string in readable form from input, sticky/"special" notes are fully supported.
Switch is easier to use & capable of doing both.
size <MODE> <POINT> <[1,MB|2,AUTO|*,KB]>
> Echos the value of specified mode on specified <POINT> (modes 1-4 are for mount points).
If incorrect mount specified, Returns errorcode. Automaticly fixes missing '/' on specified mount if
not present. Third variable specifys out format. 1 is Mb, 2 is auto (kb/mb/gb with tags), * is kb
only (default), Following Modes are supported: 1=Full size, 2=Used space, 3=Used %, 4=Free space,
5=Size (use for files/paths, will not work on mounts, added '5' on request).
stype <INPUT>
> Defines file type & offers return code based on existance. Returns the following:

> Switch permissions string from either human readable (rwxrwxrwx) or Numaric (777), or vice versa.
sysrw/sysro
> Mounts '/system' as R/W (Read/Write) & R/O (Read/Only) respectively, similar to miniscripts included
in most Roms, With the exception that it utilizes the autodetection available in script, & should
work on any device/rom.
sput <mode> <option1> <option2>
> large function resembling 'tput', rebuilt for 'light' or dumb terminals, should work for most scripts
requiring tput, use 'sput --help' for more information on available options.
toggle <string>
> Checks if <string> can be considered a "true or false" statement, eg: 'toggle 1' would be '0',
'toggle yes' is 'no', 'toggle on' is off, etc. Uses 'togglevars' string. case inspecific.
tree <path>, or tree --arguments -triggers <path>
> Displays directory information based on user input, if no input specified, Current path is used.
Allows using 'tree.cfg' in '$LocalPath' directory. Use '--help --full' for more information.
truncp [-f] <path> <length> <symbol>
> Truncate <path> to <length>, & prepend <symbol> to beginning when truncated. Default <symbol> is ".."
If '-f' switch is used, Path is truncated to <length> specificly, no exceptions, otherwise splits at
closest base to <length> (default length is 20), Eg: 'truncp /system/etc/SuperBox 12' will return:
'../SuperBox', & 'truncp -f /system/etc/SuperBox 12' will return '..c/SuperBox' (12chars precisely)
Output must never exceed <value>, Truncation does not occur unless <path> is over <length>.
uc "<INPUT>"
> Switches input to all uppercase, supports whitespace/newline, no limitations.
Included Functions (Source Only) 4a.
Please note that the functions listed here might not be a complete list of available applets for use in
source mode, & the applets listed here are unavailable in execution mode due to limitations of bash
script handling (Only available when sourced or sourced through script).
cd <path>, or cd <var> <path>
> works as a replacement/extension to shell's builtin. can auto-cd to files path if file is specified
& supports additional (unstandard) functionality, while keeping origional functionality fully intact.
Supports the following variables:
> -l | follow links to home path. (eg: 'cd /etc' would cd to '/system/etc'), defaults as on.
> -p | dont follow links to home path (oppisite of above, cds to given input).
> -c | process case insensitive (Eg: 'cd /SYSTEM/ETC' would cd to '/system/etc') Default is off.
> -m | make path if path doesnt exist, then cd to created path (nofail cd).
Variables can be passed either united, or seperate, & in any order, Eg: '-l -p -m -c' or '-lpmc'
error <id> <string1> <string2>..
> prints error message to stderr based on error 'id'. available ids can vary with build & it is not
recommended to call this function, for compatibility reasons, only ids that are garunteed to remain
unchanged are, '-1' (self-defined, no error notice), & '3' (self-defined with error notice).
Error ID & definitions start at line ~157, & continue to 'END_ERR' & can be previewed with 'printl'.
getsizes <base-size>
> used for generating spacing when generating menus in a uniform fashion, if 'base-size' is unspecified,
Script will use terminal width instead. Exports the following variables:
Cw - Custom width, overall width of panel (base-size, or columns)
Ws - Workspace, Width of 'Cw' Minus borders (Side1/Side2 & Edge) (if set).
Side - Width of sides ('Ws'/3), Use for left/right on 3-column menu.
Middle - Width of middle ('Ws'/3 & adjusted for uneven width), Use for left/right on 3-column menu.
Left - Width of left ('Ws'/2'), use for 2-column menu.
Right - Width of right ('Ws'/2 & adjusted for uneven width), Use for 2-column menu.
getvals $*
> used for functions eccepting runtime variables, & offers extended customizations when compared to
using 'shift' & 'if/case' statements. Only requires a nested 'ctrigs' function determining all
applicable switches, & a note to 'ctrigerr $1' on undefined. all additional variables passed to this
function are exported to V{1..20}. (script allows up to 20 variable/switch combinations by default).
'getvals' will auto-clean all previous user-variables before start, & clean all unused when done.
inpth <VARIABLENAME> <DEFAULTPATH>
> Checks if 'VARIABLENAME' has a directory, if not, sets 'VARIABLENAME' to 'DEFAULTPATH/VARIABLE'
used for defaulting files to correct locations, 'VARIABLENAME' must be variables name, & must be set,
setclock <mode>
> can pass variable as mode, allows '0/1' as values, exports either 12hr (0), or 24hr (1) formatted
variable (variable name 'Time') for use with 'date' Eg: 'date +$Time'
up <path> <count>
> replicates 'cd ..', if no variable passed, cd's up one level from current directory, if 'path' is
specified, cd's up 1 level from 'path', or 'count' levels up from either.
Use as either 'up', 'up <count>', 'up <path>', or 'up <path> <count>'.

Configurations:
Configurations are unneeded for execution, but can be used to set default values
To use during execution
By default, configurations are read from:
'/system/etc/SuperBox' > main (system) configurations.
'/data/local/SuperBox' > user (writable) configurations.
User configurations will override system configurations if exist.

To see what variables are exported when script is sourced, you can create a small script such as:
Code:
export > /cache/1
. sbox
export > /cache/2
cat /cache/2|while IFS= read -r i;do
[[ "$(grep "$i" /cache/1)" ]] || echo "$i"
done
$bb rm -f /cache/{1,2}
save & run, will display all re-usable variables generated by superbox.
*NOTE
Change '. sbox' to '. <name_of_script>' depending on what you named it
adding switches after '. sbox' will enable the variable associated with said switches

Yep, playing with terminal is fun xD
Not quite a full terminal, but close
Ive managed to replicate some missing binaries in script, & modify some standards to suite my needs xD
Uploading a bash 4.1.0 binary for those who want it, the 1 thing this script relies on thats not standard
Just rename to 'bash', move to '/system/bin' & chmod 755 (rwxr-xr-x), then create symlink in xbin for compatability
(some scripts will use /system/xbin/bash, while others will use /system/bin/bash, easy to resolve with symlink)
Default bashrc (/etc/bash/bashrc)
Code:
# /etc/bash/bashrc
#
# This file is sourced by all *interactive* bash shells on startup,
# including some apparently interactive shells such as scp and rcp
# that can't tolerate any output. So make sure this doesn't display
# anything or bad things will happen !
#
# Test for an interactive shell. There is no need to set anything
# past this point for scp and rcp, and it's important to refrain from
# outputting anything in those cases.
[[ $- == *i* ]] || return
#
# Bash won't get SIGWINCH if another process is in the foreground.

Updated for those few who download, fixed most broken functions & changed most default configuration names
If using configurations, you must use the new templates, original defaults still apply
If you have any issues using this build, please let me know, also, few new functions, & partially updated readme for
better definitions on new/existing options. included makeshift changelog for those who want it.
BTW. found a few binaries that work on our device, with all dependancies,
Such as:
7z (including 7za)
bc
GNU dc
GNU nano
GNU tput (with all dependancies such as terminfo db)
& various others (totaling about 30 GNU applications), just pm me if you want em. shouldnt upload as they aint my builds

MIUI Debloat + Optmizations

Hey Guys, i've made a script to debloat MIUI and to install some Kernel optimizations at the INIT.D folder plus anti Google Play Services Wakelock Script (at INIT.D as well).
Usually i use it on mi-globe and MIUI-MIX but it should work for Xiaomi.eu, Global and Chinese ROMs too (both beta and stable).
Thanks to @kevp75 for the line:
Code:
ifelse(
(is_mounted("/system")), (
assert(run_program("/sbin/mount", "-o", "remount,rw", "/system"));
), (
assert(run_program("/sbin/mount", "-o", "rw", "/dev/block/bootdevice/by-name/system", "/system_root"));
)
);
ATTENTION!! I ONLY RECOMMEND USING THE OFFICIAL TWRP, ORANGEFOX AND MAURONO UNOFFICIAL DOES NOT WORK!!
https://twrp.me/xiaomi/xiaomimi9t.html
Instalation:
1 - Reboot in to TWRP after first boot and setup.
2 - Make a nanodroid full system Backup for safety.
3 - Go to Mount and make sure SYSTEM is mounted!
4 - Run the script.
5 - Reboot in to system.
6 - Profit.
If you wipe the system partition, you will need to reboot in to the OS and back to TWRP before flash the debloat script.

"I don't want to debloat an app that it does"
To fix that, you will need to update the script your self, but it's quite easy.
1 - Download the script on a Windows based PC that has 7zip and notepad++ installed.
2 - Open the script with zip and navigate to: "META-INF\com\google\android"
3 - Extract the file "updater-script"
4 - Edit it with notepad++ and look at the app you wish it would not debloat (for example, Clean Master)
5 - The delete the line that says "delete_recursive" and the app path (ex: delete_recursive("/system/priv-app/CleanMaster"); )
6 - Save the script and push it back to the zip file
Some apps such as maps, Google Assistant and Android Auto may be debloated on the script, but if you install it via the playstore after, the script will not debloat it, as it wont be a system app anymore.
Current version: v10 (05/03/2020)

Seems to work but phone gets a bit laggy sometimes...

It may be the VM and OOM, i'll take off those "optimizations" on the next release tomorrow.
What TWRP did you use, if you don't mind me asking.

New Build Up!
Lag should stop now that i disable the VM and OOM custom parameters, plus i added CatchLog to uninstall.

Hey Guys, i've made a script to debloat MIUI and to install some Kernel optimizations at the INIT.D folder plus anti Google Play Services Wakelock Script (at INIT.D as well) and full hosts for adblock without any external app.
Now, i may add more things to debloat since this script was optimized for Redmi Note 5 Pro Whyred and even though it work on that device, on the Redmi 4X Santoni and even on a Moto G LTE Peregrine.. on 4PA TWRP it didn't work. I'm still troubleshooting why. Once i figure out another TWRP that allow me to flash it or what i'm doing wrong (since it isn't a script issue, it's a recovery problem) i'll test other system apps to debloat specific from our Mi9t DaVinci.
That being said, i would like you guys to test it, see if it work for you guys and give me a feedback to what TWRP do you guys use/ what version of MIUI you guys debloated.
Usually i use it on mi-globe but it should work for Xiaomi.eu, Global and Chinese ROMs too (both beta and stable).
Instalation:

Seems very nice I will test it. I think it's like L-Speed, NFS, FDE.AI or LKT kernel improvements but for MIUI while You are debloating stuff.
Is it working on MIUI 11?

First, thanks for the feedback guys
Yes, you got it right but it go beyond lkt once se get kcal on our device as i tune the colors too (currently disabled though).
And yes it work on miui11

New Build Up!!
Added these apps on the list to be debloated:
/system/app/XMCloudEngine

Should work fine as it don't mod the rom, just debloat and add scripts

I'm testing new parameters for ram management and virtual memory. Next new build should be smoother

New Build Up!
Changes on Kernel tuneup:
sysctl -w net.ipv4.tcp_congestion_control=cubic
echo '16384,20736,24576,32256,85296,120640' > /sys/module/lowmemorykiller/parameters/minfree
echo '75' > /proc/sys/vm/swappiness
echo '17' > /proc/sys/vm/dirty_ratio

Successfully installed on EU 9.9.26 everything is ok, let's show the battery statistics in a couple of days, thanks for your work

Hey Guys, i've made a script to debloat MIUI and to install some Kernel optimizations at the INIT.D folder plus anti Google Play Services Wakelock Script (at INIT.D as well) and full hosts for adblock without any external app.
Now, i may add more things to debloat since this script was optimized for Redmi Note 5 Pro Whyred and even though it work on that device, on the Redmi 4X Santoni and even on a Moto G LTE Peregrine.. on 4PA TWRP it didn't work. I'm still troubleshooting why. Once i figure out another TWRP that allow me to flash it or what i'm doing wrong (since it isn't a script issue, it's a recovery problem) i'll test other system apps to debloat specific from our Mi9t DaVinci.
That being said, i would like you guys to test it, see if it work for you guys and give me a feedback to what TWRP do you guys use/ what version of MIUI you guys debloated.
Usually i use it on mi-globe but it should work for Xiaomi.eu, Global and Chinese ROMs too (both beta and stable).
Instalation:
1 - Reboot in to TWRP after first boot and setup.
2 - Make a nanodroid full system Backup for safety.
3 - Run the script.
4 - Reboot in to system.
5 - Profit.

Thanks Alot.

Just flashed V4. I don't know what you did, but it's much smoother now

What does the no host means? Edit... No need I got it now
