adb uninstall command doesn't work in Bash shell for statement [duplicate]

Question

For work reason, I need to uninstall and reinstall several apps in Android device. To do it quickly, it's easy for me to write a script to do this so that I don't need to type it again and again. Here is my script:

#!/bin/sh #adb uninstall com.company.myapp for i in `adb shell pm list packages|grep company|awk -F':' '{ print $2 }'`; do echo adb uninstall "$i" adb uninstall "$i" done 

The odd thing is `adb' always prints "Failure" while 'echo' prints the right command. The second line will work fine if uncomment it.

Anyone can help to figure out what the problem is?

Answer 1

'Failed' ... i used dos2unix to get around this same issue, but like tr -d "\r" better. Not every adb shell command appends the MSDOS CRLF, but only some some of the time.

adb uninstall failed

Is necessary dos2unix command, in the next example I'll show implementation:

#!/bin/bash #################################################################### # ADB Uninstall Util (GPL license, author: @hpsaturn) # # Dependencies: android-tools-adb, dos2unix # # Revision: # ----------------------------------------------------------------- # 20171005 get package name (without execution) # 20171019 filter for multiple apks and execution ready #################################################################### pkg=`adb shell 'pm list packages -f' | sed -e 's/.*=//' | grep $1` cnt=`echo "$pkg" | wc -l` adb=`echo "$pkg" | sed -e 's/^/adb uninstall /'` cmd=`echo "$adb" | dos2unix` if [ "$pkg" = "" ]; then echo "package not found!" exit 1 elif (( $cnt > 1 )); then echo "" echo "multiple packages found:" echo "" echo "$pkg" echo "" else echo "uninstalling: $pkg" bash -c "$cmd" fi
