CRON(8)                 FreeBSD System Manager's Manual                CRON(8)

NAME
     cron - daemon to execute scheduled commands (Vixie Cron)

SYNOPSIS
     cron [-x debugflag[,...]]

DESCRIPTION
     Cron should be started from /etc/rc or /etc/rc.local.  It will return
     immediately, so you don't need to start it with '&'.

     Cron searches /var/cron/tabs for crontab files which are named after
     accounts in /etc/passwd; crontabs found are loaded into memory.  Cron
     also searches for /etc/crontab which is in a different format (see
     crontab(5) ). Cron then wakes up every minute, examining all stored
     crontabs, checking each command to see if it should be run in the current
     minute.  When executing commands, any output is mailed to the owner of
     the crontab (or to the user named in the MAILTO environment variable in
     the crontab, if such exists).

     Additionally, cron checks each minute to see if its spool directory's
     modtime (or the modtime on /etc/crontab) has changed, and if it has, cron
     will then examine the modtime on all crontabs and reload those which have
     changed.  Thus cron need not be restarted whenever a crontab file is
     modified.  Note that the crontab(1) command updates the modtime of the
     spool directory whenever it changes a crontab.
