    Excellent article, I am not too clear on Run perlscript.pl at 23 minutes after midnight, 2am and 4am, everyday: so will be checking that format, keep up the great work

    One thing to remember is that if the cron user is supposed to run a script that assumes that the (normal) user environment exists for the script, then the user is mistaken; the cron function needs to read in the user’s environment via ‘source /home/user/.bashrc‘ before the actual ‘/path/to/script.bash‘ is called.

    So when testing the script, state the full paths to the binaries called inside the script,or set the paths needed inside the script via ‘PATH=${PATH}:/path/to/binary1:/path/to/binary2

    CRON is a Linux tool for scheduling and performing repetitive tasks.
