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 th

Answer 1

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

Answer 2

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 :)

Answer 3

This works for me:

adb shell "su -c ./data/local/tcpdump-arm -s 0 -v -w /data/local/appxpress_dump.pcap"

Answer 4

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

Answer 5

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.

Answer 6

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"
