adb push in a script

I have a simple bash script to push an executable to the android and then remove it.
#!/bin/bash
adb push CMakeBuild_Android_armv8/Out/Release/exec /data/local/tmp/exec
adb shell rm data/local/tmp/exec
This is saved as 'adb_push.sh'. I made sure that this is an executable via chmod.
chmod +x adb_push.sh
But when I run this script in the Cygwin ./adb_push.sh, I get an error that there is no such directory.
CMakeBuild_Android_armv8/Out/Release/exec: 1 file pushed, 0 skipped. 62.5 MB/s (7302616 bytes in 0.111s)
rm: data/local/tmp/exec: No such file or directory
Is there any obvious steps that I am missing in creating a bash script or is there any error in what I am doing?
Any hint or comment would be highly appreciated.
ADB version:
$ adb version
Android Debug Bridge version 1.0.41
Version 31.0.0-7110759
Installed as C:\platform-tools_r31.0.0-windows\platform-tools\adb.exe
Disclaimer: I already tried putting the source and destination path in quotes, it did not work for me. Also tried the same with a .wav file instead of an executable and I get the same error which lead me to believe that something's not right in the bash script.

Your second command assumes the working directory is the root /. It appears this assumption is false.
The first command is succeeding. Only the second command is failing.
If adb shell doesn't start at the root (/), then the destination path you supply in the first command (/data/local/tmp/exec) is different from the path you supply in the second command (data/local/tmp/exec, note the missing slash at the beginning).
I'm gonna guess adb shell on your device starts a shell in some user's home directory, not /.
Option 1: Use absolute file path
You can fix this by giving the full absolute file path in your second command:
adb shell rm /data/local/tmp/exec
Option 2: Change directories before your command
Alternatively, you can change to the root directory before running the command. adb shell (as of version 31.0.0-7110759) does not have the ability to set the working directory, but you can do this inside the shell by adding a cd before your rm. Note that the command must now be quoted to prevent your local shell from interpreting the list operator &&:
adb shell 'cd / && rm data/local/tmp/exec'
Note: The adb shell default working directory may vary by device or ROM. On my stock Pixel 3 it does in fact start at the root:
$ adb shell pwd
/

How to remove file on android using ADB

I am trying to remove a file on my android using a single ADB command.
I understand you can just do adb shell and then remove the file using rm.
But I need it to be a one line execution.
I’ve tried:
adb rm-f /directory/file.txt
adb shell rm-f /directory/file.txt
Both don’t delete the file I want.

Delete file on android:
adb shell rm sdcard/download/file.ext

I noticed in your comments you are looking for one line execution since you're gonna be using Python. Well as an alternative you could use the subprocess module to write to stdout allowing you to execute as many commands of choice
for example
import subprocess
process = subprocess.Popen([r'adb', 'arg1', 'arg2'], stdout=subprocess.PIPE,stdin=
subprocess.PIPE) #start adb
process.stdin.write('shell \n') # Parse in input into the program
process.stdin.write('rm *\n') # Parse in second input
line=process.stdout.readline() # Read a line from stdout

It worked for me to run the following command:
adb shell rm -f -rR -v /sdcard/Documents/

"adb shell ls" displays broken folder and file names

"adb shell ls" displays broken folder and file names like below. It seems that the broken strings are prepended at the header and appended in the tail of the names.
What could cause it?
Note that I'm running adb which is installed in embedded Linux.
===========below==========
C:\Users\user>adb shell ls
[1;34mbin[0m [1;34mdev[0m [1;34mlib[0m [1;34mmnt
...

Try running
adb shell command ls
Read more about command here.
Relevant text from the above link :
Only shell builtin commands or commands found by searching the PATH are executed. If there is a shell function named ls, running `command ls' within the function will execute the external command ls instead of calling the function recursively.

Applescript do shell script can't find Android ADB

I have a couple of shell scripts stored in the /Scripts folder of my AppleScript application.
I can access them by setting my base path
set basePath to POSIX path of ((path to me as text)) & "Contents/Resources/Scripts/"
But I'm only able to run the script if I call the Terminal app
-- This works
tell application "Terminal"
set currentTab to do script (basePath & "install_key.sh")
end tell
-- This does not work
do shell script basePath & "install_key.sh"
The error on do shell script complains about not being able to find adb (Android Debug Bridge)
FWIW, here is the shell script in question (install_key.sh)
#!/bin/bash
#Find script directory
DIR="$( cd "$( dirname "$0" )" && pwd )"
adb push $DIR"/key-dev.txt" /sdcard/ &&
adb shell mv /sdcard/key-dev.txt /sdcard/key.txt

Problem
If I understand correctly, your main issue is that your script cannot detect and hold the presence of a specific command located on a system.
Solution
I believe the following code will be effective in helping you achieve your goal. This applescript allows you to find whether ADB is stored on a system and store it's path in a variable. You can add the variable to your path and export as others have suggested or have a look at the export process in Apple's TN2065.
If ADB is not found on a system then users can receive a prompt telling them what actions to take (if that aligns with your use-case or you could begin the install sequence for ADB). To test the behavior of the script you can simply change the adp to some other (fake) command that does not exist on your system. I've added the path to the dialog so that you can see the do shell is passing the contents of the which command into a variable.
try
set adbPath to do shell script "which adb"
on error errStr number errorNumber
-- If our own error number, warn about bad data.
if the errorNumber is not equal to 0 then
display dialog "ADB is not loaded onto system. Please load ADB and run this app again"
return 0 -- Return the default value (0).
else
-- An unknown error occurred. Resignal, so the caller
-- can handle it, or AppleScript can display the number.
error errStr number errorNumber
end if
end try
if length of adbPath > 0 then display dialog "ADB found continue processing..." & adbPath
The structure defined in the TN2065 above is essentially:
$ VAR=something; export VAR $ osascript -e 'do shell script "echo $VAR"' something
You might also want to try the administrator option when calling the shell script:
do shell script "command" user name "me" password "mypassword" with administrator privileges

The Technical Note TN2065: do shell script in AppleScript is the key reference for this kind of issues.
when you use just a command name instead of a complete path, the shell
uses a list of directories (known as your PATH) to try and find the
complete path to the command. For security and portability reasons, do
shell script ignores the configuration files that an interactive shell
would read, so you don’t get the customizations you would have in
Terminal.
First: find the full path of adb
you have to open a Terminal and issue the following command:
$ which adb
suppose the response is:
/Users/ronda/projects/android/sdk/platform-tools/adb
this means that the path of adb is:
/Users/ronda/projects/android/sdk/platform-tools
, now we have several way to address the problem, for example follow one of these two options:
Option1: Fix the AppleScript
do shell script "PATH=${PATH}:/Users/ronda/projects/android/sdk/platform-tools; export PATH; echo $PATH; " & basePath & "install_key.sh"
Option2: Fix the shell script
for example you could specify full path to the adb command in your .sh this way:
#!/bin/bash
#Find script directory
DIR="$( cd "$( dirname "$0" )" && pwd )"
/Users/ronda/projects/android/sdk/platform-tools/adb push $DIR"/key-dev.txt" /sdcard/ &&
/Users/ronda/projects/android/sdk/platform-tools/adb shell mv /sdcard/key-dev.txt /sdcard/key.txt

The simplest solution would be running the same bash configuration as your terminal application. The main difference is that Terminal uses an interactive bash and do shell script command doesn't. To run an interactive shell you can simply execute a new one with option -i (stands for interactive). When an interactive shell is opened the ~/.bashrc file is used, while non-interactive shells don't use this file.
do shell script "bash -i <<<" & quoted form of (basePath & "install_key.sh" as text)
if you don't like that you can simply execute the bashrc file or read the path variable and set it in a do shell script.

Launch a script as root through ADB

I have created a script to mount partitions and do some stuff in my Android system. I saved the script as install.sh in the /bin folder of Android.
I want to call the script from ADB, which is itself called from a batch file on Windows, but it needs to be executed as root.
The first solution I tried was to call the script using
adb shell "su -c sh /bin/script.sh"
but it does not work as it gives me a shell access (with root permissions), but nothing is executed.
I also tried to call
adb root "sh /bin/script.sh"
but I got the following error
adbd cannot run as root in production builds
I then tried to write
su -c "command"
for all the commands which need a root access in my script, but I have the same problem.
When I run the script I only obtain a root shell and nothing is executed.
If I use the first solution by hand (e.g. I call adb shell su, then my script), it works. However the whole point is to automate the process, so that adb shell can be called from another script.
Do you have any idea of how I could achieve this ?
Thanks !

This works for me:
Create myscript.bat and put into it (note the single quotes around the commands to be executed in superuser mode):
adb shell "su -c 'command1; command2; command3'"
then run myscript.bat from a DOS shell.
Note: it doesn't appear that the the DOS line continuation character (^) works in this situation. In other words, the following doesn't work for me:
adb shell "su -c '^
command1; ^
command2; ^
command3'"
This results in "Syntax error: Unterminated quoted string"

This works :
adb shell echo command which needs root privileges \| su
If you need redirection:
adb shell echo 'echo anytext > /data/data/aforbiddenfolder/file' \| su
For "copying" a local file to an android path needing root privileges (but alocalfile must not contain '):
cat alocalfile | adb shell echo "echo '`cat`' > /data/data/aforbiddenfolder/file" \| su
If you have a better way (even for su versions which don't have -c), I am interested.

This works for me:
adb shell "su -c ./data/local/tcpdump-arm -s 0 -v -w /data/local/appxpress_dump.pcap"

I am not sure if I provided a solution or asked for a better one.
I wanted to run some 200 command in batch mode to be sent to adb
I followed this approach
adb shell "su -c command ; "
adb shell "su -c command ; "
adb shell "su -c command ; "
adb shell "su -c command ; "
and I saved them in a batch file
This command
adb shell "su -c 'command1; command2; command3'"
will not work beyond a certain max size . It did not work
error: service name too long

but it does not work as it gives me a shell access (with root permissions), but nothing is executed.
How do you know that you are given root permissions? I assume you are attempting to execute the script on a device? Has your device been rooted?
You may need to give execute permissions via chmod to the file.
chmod ugo=rwx /bin/script.sh

It appears that I was using a very simple version of su which did not accept the -c argument.
I copied another su which did work. AndyD is totally right though, so I am accepting his answer instead of mine :)
