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

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?

Let me answer it by myself now. There is '\r' in package name. So using `tr -d "\r"` to delete this char will work. — Eric Zhao, Sep 26 '11 at 05:43

'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
