CROND(8) UNIX 5.0 (6 March 1987) CROND(8)
NAME
crond - daemon to execute scheduled commands (Vixie's Cron)
SYNOPSIS
crond
DESCRIPTION
Crond should be started from /etc/rc or /etc/rc.local. It
will return immediately, so you don't need to start it with
'&'.
Crond searches for a crontab file for each user listed in
/etc/passwd; those crontabs found are loaded into memory.
Crond 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, if such exists).
Additionally, crond checks each minute for the existence of
a POKECRON file in it's spool directory. If it exists, it
is removed, and crond will reload its memory-resident cron
tables. Crontab(1) creates the POKECRON file whenever it
makes a change to any crontab.
