Using adb in bash is giving different results than expected

Question

I have a bash script for uninstalling some software that is loaded onto our devices.

#!/bin/bash APKS=`adb shell pm list packages projects` for apk in $APKS do apk=${apk##package:} echo "Uninstalling: $apk" adb uninstall $apk done 

When i run this script, all of the commands to uninstall an apk fail. However, when i run the exact same command (adb uninstall projects.abd.def) outside of the bash script, it executes successfully.

What am i doing wrong in the bash script?

Answer 1

I figured out the issue. I assumed there was a carriage return in the variable and had tested for this and it was still not working.

However, after googling a little more, i realized i was chopping off the carriage return incorrectly.

Here is the correct way:

apk=`echo -n ${apk} | tr -d "\r"`
