“There are certain things that you have to do regularly on
your Linux system, like emptying your /tmp/, rotating your logfiles
or creating a backup. Fortunately you don’t have to do these
repetitive tasks yourself, cron can handle them for you. Cron
is a daemon which executes commands in regular intervals and mails
the output of the command to you (or someone else).”
“In order to config the cron daemon, you have to edit your
crontab file by running “crontab -e”. This command will create a
crontab for you (in case you don’t already have one) and run the
editor set in the VISUAL or EDITOR environment variable to edit the
crontab file…”
