I am trying to evaluate a boolean variable in Bash scripting, but it always return false.
Here is the code:
DEVICE_FOUND=false
tmp=`adb devices | tail -n+2 | awk '{print $1}'`
echo "$tmp" | while read line
do
if [ "$DEVICE_ID" = "$line" ]
then
echo "Found a device"
DEVICE_FOUND=true
fi
done
if ! $DEVICE_FOUND
then
echo "ERROR: The device "$DEVICE_ID" is not connected"
exit
fi
Whether or not "Found a device" gets executed or not, I always go into the if statement. When DEVICE_FOUND=true, it should not go in the last if but it does.
I do not understand why is that.
Does anyone please know?
Thank you very much.
