How to use su command over adb shell?

Question

I need to make a script that executes a lots of thing on Android device, my device is rooted, when I enter on the shell, I can give the command su, and it works but I need pass this command like:

adb shell "
su;
mv /sdcard/Download/app_test /data/local;
cd /data/local;
./app_test;
exit;
exit;
"

when I put some commands before the su it works, according what I read su creates a new shell that return immediately, but I need give commands on the su shell, how can I do that?

Answer 1

Well, if your phone is rooted you can run commands with the su -c command.

Here is an example of a cat command on the build.prop file to get a phone's product information.

adb shell "su -c 'cat /system/build.prop |grep "product"'"

This invokes root permission and runs the command inside the ' '.

Notice the 5 end quotes, that is required that you close ALL your end quotes or you will get an error.

For clarification the format is like this.

adb shell "su -c '[your command goes here]'"

Make sure you enter the command EXACTLY the way that you normally would when running it in shell.

Answer 2

On my Linux, I see an error with

adb shell "su -c '[your command goes here]'"

su: invalid uid/gid '-c'

The solution is on Linux

adb shell su 0 '[your command goes here]'

Answer 3

The su command does not execute anything, it just raise your privileges.

Try adb shell su -c YOUR_COMMAND.
