Comment on Bash Tip: Exit on Error by Jason

One way would be to add “|| true” to the end of commands that you don’t care about the exit code of. So:

egrep ‘[a-z]+’ myfile.txt || true

You can specify real devices attached to USB in the same way, you just need the serial number. You can see this in the output of “adb devices” (first column). Just set adb.device.arg to “-s “.

What to do if the exit-on-error is mixed with the opposite. That is, sometimes I need exit on error, sometimes I don’t Want to exit if the return value is not 0.
For example, if egrep does not find the pattern in a given string, it returns 1. In this case I don’t want to exit.

A simple solution is to guard the statement with set +e and set -e. But this will make the scripts looking messy.

Is there a better idea?

there is no way to use ant install with devices?
eve this way:
ant -Dadb.device.arg=”-s emulator-5554″ install
you specified just the emulator not a real device.

suggestion? thanks
