Your scheduler may not allow you to run a perl script with the directive in front,  perl /usr/interfaces/scripts/ccs_rename.pl.My scheduler doesn't

You may be having a permissions issue with the scheduler. To fix this you will need to give the scheduler permission to run your script. This can be accomplished with the unix command chmod. I would do something like  chmod 750 /usr/interfaces/scripts/ccs_rename.pl Then just schedule your script to run directly as '/usr/interfaces/scripts/perl ccs_rename.pl '
