How will I know if cron daemon is running in my Slackware installation? I tried the code below and it returns me nothing. It means cron is not in /etc/rc.d folder.

ls /etc/rc*.d | grep crond
  • Enabled or running? – Jeff Schaller Feb 28 '19 at 3:01
  • @JeffSchaller-> Identify if it is running. If it is not, atleast enable. – aegc Feb 28 '19 at 3:09

    Can you try ps -ef | grep cron and see if it returns anything? – Haxiel Feb 28 '19 at 7:24
  • Which cron? Williamson? Dillon? Vixie? Guenter? Godouet? Jackson? Mašláňová? – JdeBP Feb 28 '19 at 8:35

    @Eliyah The ps command shows running processes, and that first line is your cron daemon. So yes, the cron daemon is currently running on your system. – Haxiel Mar 1 '19 at 3:33

On Slackware some daemons/services do not have separate script in /etc/rc.d/ directory and are run directly from /etc/rc.d/rc.M script (or rc.S when you start not in multiuser but single mode). Try:

grep /etc/rc.d/ -r -e "cron"

So it's running by default on Slackware, unless you comment it out manually in rc.M.

Also on Slackware only rc.d is used. You can ignore all rc[0-6].d directories. This directories are provided only to ease your pain if you install some non-Slackware packages that crash without them.
