[Q] Install busybox

Anyone knows how to install busybox?
I've tried to follow some guides but ends up with:
Code:
215:Desktop ricardo$ adb push busybox /data/local
580 KB/s (1083568 bytes in 1.823s)
215:Desktop ricardo$ adb shell
$ su
# cd /system/xbin
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# cat /data/local/busybox > busybox
cannot create busybox: not enough memory
or
$ su
# cd /data/local
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# dd if=/data/local/busybox of=/system/xbin/busybox
/system/xbin/busybox: cannot open for write: Out of memory
or
$ su
# cd /data/local
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# ./busybox cp /data/local/busybox /system/xbin
cp: can't create '/system/xbin/busybox': Cannot allocate memory

same here. cannot write to rw-mounted /system.
sucks

Try my zip file. Woked for me
The only thing that I want to change and I can't is the init.rc file. I tried to mount the / (rootfs) with rw, but every time I restart my device the file is copied, again, from the ramdisk image.

I have the same problem

What should I do with your files?
Nobody has a solution to this?

I don't think this is a memory issue though, .. added 512mb swap and still it claimed to be out of memory, ..
also I figured maybe hd space .. however when i ln /data/local/tmp/busybox to /system/xbin it had the same error.
I both tried ln from the system and ln from busybox both had same result.

It's not a memory problem! In order to install it you have to be in recovery mode.
Try:
While in recovery mode use adb to connect to our phone. Now transfer the zip file (busybox.zip) to your phone and install it via clockwork recovery -> install zip file -> select my zip file.

can anyone post the proper busybox file cause for some reason the file signature verification failed.
adb push busybox-signed.zip /sdcard/busybox-signed.zip
rebooted phone held down volume button while booting ..
choose recovery, ..
choose install zip from sdcard..
then i see a lot of no and one yes .. so i choose yes but the installation is aborted.

Just install titanium backup and click on 'problems?' at the bottom. It will install BusyBox for you.

it has error during installation at line 4 with your busybox.zip
somethinf like can not chmod
(rooted buzz with stock rom)

Do what this guy said.

titanium install in /sdcard busybox, not in /system/bin (xbin) , so it is not usuable by other apps

i have installed it in during recovery mode in /system/xbin
how now to specify PATH for using commands from it?

you have read my mind especially since that isn't free software.

i think you need to create aliases however why install it in xbin anyways then, .. if you need to create aliases or links in bin.. ?
example
$ ln -s /data/local/tmp/busybox ls
$ ./ls
if it is in a path that is included in PATH executing a command will auto look for it in all directories defined in PATH env so basicly you could just create all the directories under /data/local/tmp/bin
and just then append that to PATH env echo $PATH then append :/data/local/tmp/bin to it and busybox should work as well.

titanium backup is free software... look on the market, there's a free version and a donate version.

i have aliases in /system/xbin
they was created after busybox --instal -s
but in system allready exists some commands like ls => i want to use ls from busbox, not from system
and terminal emulator dont anderstand ^[ likes bindings

is there a definitive way to do this. There seems to be no clear way of doing it.

To install:
1) extract and push busybox to your sdcard, reboot into recovery
2) mount /system
3) if you don't have /system/xbin (you should), create it
adb shell:
# mkdir /system/xbin (if necessary)
dd if=/sdcard/busybox of=/system/xbin/busybox
cd /system/xbin
chmod 755 busybox
./busybox --install .
4) reboot and done
OPTIONAL - before rebooting replace the busybox installed by the root process in /system/bin
1) mv /system/bin/busybox /system/bin/busybox.bak
2) cp /system/xbin/busybox /system/bin/busybox

The above is pretty straightforward. The only thing is you need to download the zip in the other thread and 'busybox' refers to the binary in the zip rather than the whole directory - as I understand it. Correct me if I am wrong but trying the dd command on the dir will not work.

You dont have to extract the binary into a folder, just extract the busybox file direct on your sdcard. Than the dd command should work, on my phone it works fine.
But if not, does the command cat in the adb shell work?
If so, try istead of the dd comand:
Code:
mount /sdcard
cat /sdcard/busybox > /system/xbin/busybox
And remember to start your wildfire in the recovery mode, that was the mistake I had done...

In terminal, granting su permission first, then type:

Shell commands

Here you will find a list of some shell commands you can use on your android phone, either with a terminal emulator or over adb shell from your PC. I would recommend using connectbot as your terminal emulator.
The commands listed are in no way limited to what is described below, I am just scraping the surface here. For more information on these commands type ' --help' after your command, e.g. 'mount --help' or use google, most of these commands are exactly the same as what you would find on any Linux system, so you will find EXTENSIVE information on the web if you want to know more.
These commands work on my HTC Desire running Cyanogenmod 6 (Android 2.2), most, if not all of them should work on other devices and/or roms.
If you have any suggestions post them below or pm me and I will edit this post to include them.
Notes
Most of these commands require root privileges, type su first.
Everything after a # is a not and not a part of the command.
busybox
What it does
Provides a selection of commands not built into android by default.
Example(s)
busybox cp a b
Notes
busybox is included in most custom roms and has aliases set up so you do not need to type busybox before the commands eg, 'cp' is the same as 'busybox cp' in most custom roms.
cat
What it does
Prints the contents of a (text)file onscreen.
Example(s)
cat file
cd
What it does
Changes the current directory. You may find it easier to change to the directory you will be working in before issuing other commands so you dont need to include the full path in your commands.
Example(s)
cd .. # Go up 1 directory level, eg go from '/sdcard/download/ to '/sdcard'.
cd /sd-ext # Change to '/sd-ext'.
chmod
What it does
Makes a file executable
Example(s)
chmod 755 /data/bin/yourbin
cp
What it does
Copies files/directories
Example(s)
cp filea fileb
cp -rf directorya directoryb # Copy entire directory recursively and forces copy.
df
What it does
Displays information on all mounted filesystems (free space).
Example(s)
df -hm # Show disk usage in human readable format in Megabytes.
du
What it does
Diplays the size of files/directories.
Example(s)
du -md 1 # Prints the size of all directories in Megebytes.
du -sh file # Prints the size of file in human readable format.
du -sh directory # Prints the size of directory in human readable format.
export
What it does
Sets environment variables.
Example(s)
export PATH=$PATH;/sd-ext/bin;
free
What it does
Display the amount of free and used system memory
losetup
What it does
Associates loop disk images with loop devices.
Example(s)
losetup /sdcard/disk.img /dev/block/loop7
Notes
Android 2.2's implementation of apps2sd uses one loop device for each app saved to SD. There are 8 loop devives by default (loop0-loop7) so if you have 8 or more apps saved to SD you will not be able to use this command. There is no issue when using 'oldschool a2sd'
ls
What it does
List Directory contents.
Example(s)
ls -a # List directory contents including hidden contents.
mount
What it does
Mounts a filesystem.
Example(s)
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 # Remounts /system as writable.
mount -o remount,ro -t yaffs2 /dev/block/mtdblock3 # Remounts /system as read only.
mount -t ext2 /dev/block/loop6 /sdcard/disk # Mount loop6 on /sdcard/disk.
mount /sd-ext /sdcard/sd-ext # Mount /sd-ext on /sdcard/sd-ext.
Notes
On other devices it may be possible to mount disk images without going through losetup and using the option -loop in mount instead.
If you are having trouble with mount try using busybox mount instead, the busybox version seems more capable than the one shipped with Android.
mv
What it does
Move/rename files/directories
Example(s)
mv download/file stuff/file
mv picture4.jpg mydog.jpg
ping
What it does
Pings a server to check for conectivity.
Example(s)
ping -c 5 http://www.google.com # Ping google 5 times
Notes
if you do not include the -c option ping will work indefinatly.
pwd
What it does
Prints the current directory.
rm
What it does
Remove file/directory.
Example(s)
rm file
rm -rf directory # Delete a directory and its contents.
rmdir
What it does
Removes a directory
Example(s)
rmdir emptydir
Notes
If a directory has contents us 'rm -rf' instad.
su
What it does
Gives you root privelages.
touch
What it does
Makes an empty file
Example(s)
touch file.txt
wget
What it does
Download things from http or ftp.
Example(s)
wget http://www.google.com

Excellent, thank you.
Just what the doctor ordered for n00bs like me

[Q] Run script on FireTV boot

I have a very simple script to mount my NAS to a specific path that I want executed every time my FireTV boots.
I have read about pointing to it in the install-recovery-2.sh, however that is not available on my FireTV. I have also read about placing the script in system/etc/init.d/ however that path doesn't exist on the fireTV either.
Would prefer to do this at the system level and not rely on a manager (Tasker, Script Manager, etc).
Anyone have any experience?
Update w/ solution:
I was able to get this working by placing a script called install-recovery.sh in /system/etc/ . Make sure that permissions are set appropriately (at least 755). If creating the script on a Windows machine, make sure there aren't any hidden whitespace characters (I personally verified the script using SManager on my Fire TV).
Code:
[B]sleep 15[/B]
mkdir /mnt/obb/nas
chmod 777 /mnt/obb/nas
[B]sleep 20[/B]
mount -o noperm,unc=\\\\192.168.1.147\\Public,username=xxxxxx,password=xxxxxx -t cifs none /mnt/obb/nas
The sleep command is necessary as the script may run before the network is initialized.
Thanks rbox and ECEXCURSION!

That is a very good question How can I test that my script is functioning?
From adb shell or Terminal emulator I type the following commands to mount my NAS:
Code:
su
cd /mnt/obb/
mkdir nas
chmod 777 nas
mount -o noperm,unc=\\\\192.168.1.147\\Public,username=xxxxxx,password=xxxxxx -t cifs none /mnt/obb/nas
To turn this into a script I just dumped it into notepad and added #!/system/bin/sh to the top and saved it as install-recovery.sh.

Run it from adb, but right off the bat, I can tell you you need to chmod 755 it atleast before that will work.

Well first of all, don't run it with sh... it needs to have #!/system/bin/sh at the top, and you need to run it directly. Second, don't put su in it because it's already running in the root context.

That sounds strange... but you'll need to run su before running it, because it needs root. It could be that its not in UNIX file format. If you edited it on Windows you need to use an advanced editor that has the ability to save as UNIX format.

Unix file format appears to have been the issue. When I opened it with SManager I saw some nasty whitespace characters. Removed those and the script works as expected:
Code:
[email protected]:/data/media/0 # ./install-recovery.sh
./install-recovery.sh
[email protected]:/data/media/0 # cd /mnt/obb/nas
cd /mnt/obb/nas
[email protected]:/mnt/obb/nas # ls
ls
Games
Photos
Shared Music
Shared Videos
eBooks
key.txt
[email protected]:/mnt/obb/nas #
After confirming the script worked as expected, I moved it to /system/etc/ and verified permissions were acceptable (777). Upon reboot I see that the /mnt/obb/nas is created, however the NAS is not mapped.
Can you comment, when is the install-recovery.sh called in the boot up process? Is it possible that the CIFS module isn't fully loaded when this is called? Alternatively, is there a log that I could reference to see if any error occurred while running the script at startup?

It's probably running before the network comes up. There might be maybe some kind of regular android apk that will run a script when the network comes up. There might be a way to just stick a loop in your current script waiting for something, not sure.

You could probably just add "sleep 30" to the beginning of the script.

Thanks, will give that a try when I get back home.
Edit: It worked! Thanks to the both you for your input.

Just wondering since I'm a newbie when it comes to this one. Does mounted folder have to be in /mnt/obb or can I choose any directory I want?

help me please I cannot modify system files despite having root

i'm on (pixel 2xl) lineageos 16.0 rooted with magisk, i want to add a script in init.d folder but i can't do it, i tried with root explorer but it doesn't work, afwall also can't mount folder for startup script, any solution?

Why? What error do you get?
Try to move/copy something into /tmp folder. It should work if you're rooted (your shell shows # instead of $).
If it doesn't work, maybe you have to remount your system as rw (read and write):
Code:
mount -o rw,remount /
after you made your modifications, mount it as ro (read only) again:
Code:
mount -o ro,remount /
If it still doesn't work, we need to see the error you get (copy and paste into this forum) while moving/coping something into /tmp.

Can you verify you entered that command as root?
Please do the following:
Do this on your computer to enter your devices shell
Code:
prompt_PC:~$ adb shell
Code:
prompt:~$ whoami
This should give you either "shell" or "root"
If it says "shell" do:
Code:
prompt:~$ su
prompt:~#
It will show a # instead of $ if you're root.
If you're already root (or you are now root due to su command), do:
Code:
prompt:~# mount -o rw,remount /
Now it should be writeable and you can do your modifications.
After you finished you need to change it to ro (read only) again:
Code:
prompt:~# mount -o ro,remount /
After that you can exit the shell:
Code:
prompt:~# exit
prompt:~$ exit

Can you verify you entered that command as root?
Please do the following:
Do this on your computer to enter your devices shell
Code:
prompt_PC:~$ adb shell
Code:
prompt:~$ whoami
This should give you either "shell" or "root"
If it says "shell" do:
Code:
prompt:~$ su
prompt:~#
It will show a # instead of $ if you're root.
If you're already root (or you are now root due to su command), do:
Code:
prompt:~# mount -o rw,remount /
Now it should be writeable and you can do your modifications.
After you finished you need to change it to ro (read only) again:
Code:
prompt:~# mount -o ro,remount /
After that you can exit the shell:
Code:
prompt:~# exit
prompt:~$ exit
(first exits su, second exits shell)
