or if the systemd init system is being
used:
systemctl start|stop|restart|reload|status autofs.service
/autofs reload or systemctl autofs.service reload will check the current auto.master map against the current automount managed mounts. It will terminate those daemons or threads (depending on autofs version) whose entries have been removed, re-read the automount maps for entries that have changed and start new daemons or threads for entries that have been added.
If an indirect map is modified then the change will become effective immediately. If an indirect map uses the browse option, the master map contains direct mount maps or the auto.master map is modified then the autofs service control reload action must be rerun to activate the changes.
/autofs status or systemctl autofs.service status will display the status of, automount(8) ,running or not. When using the systemd init system the status output includes somewhat more information related to the service status.
systemctl(1) has more functions than the actions mentioned here, see systemctl(1) for more information.
