wrapping a perl script in bash - echo to IRC bot

I have a perl script - wow.pl. I want to write a wrapper that will run the script and if it exits successfully, echo a message to the IRC chat windows that listens on port 4514 on foo400host. The echo works, but the script does not necessarily run. 

#!/bin/bash
if [ ~/scripts/wow.pl ] 
   then 
       echo "wow.pl is done" | /home/bin/nc foo400host 4514
fi
Solution

  • You need to check the return status of your script, you can do this using $?

    /usr/bin/perl ~/scripts/wow.pl
rc=$?
if [[ $rc == 0 ]] ; then
   echo "wow.pl is done" | /home/bin/nc foo400host 4514
fi
exit $rc
