How to determine if a script (perl) was called from a CRON job or commandline

Report from cron vs. command line
cron is pretty good about reporting to the user its status, i.e. whether it's running / active. If you're suspicious, then I would suggest placing an echo
statement (1.) in the/(a) cron script and noting its affect. I suggest you have a look at the man page for cron as well.
1. echo "This output has been created by cron..."
Good luck!
