cron(lM) cron(lM)
NAME
c ron - clock daemon
SYNOPSIS
/etc/cron
DESCRIPTION
cron executes commands at specified dates and times. You can
schedule commands regularly with instructions in crontab files;
other users can submit their own crontab file with command
crontab(l). Use at(l) for commands which execute only once.
Since c ron never exits, you should should only execute it once.
cron is listed in the /etc/inittab file and is therefore started
directly by ini t(lM).
cron examines crontab files and at command files only during
process initialization and when a file is updated using crontab.
This reduces the overhead of checking for new or changed files at
regularly scheduled intervals.
