These are a few commonly used commands.
For more, see the manual pages of the service-control
, system-control
, shutdown
, and rcctl
programs.
For exposition, we here assume that the cron service has its service bundle directory at, or accessible via a symbolic link at, /var/service-bundles/services/gcron
.
Daemontools-style service management employs direct access to the service bundle directories.
OpenBSD-style, systemd-style, and SMF-style service management searches for service bundle directories in several well-known locations.
The cron service (located in such a location) is simply denominated either cron.service
or simply cron
.
Associated log services are conventionally denominated cyclog@
service-name, and pointed to from the logged service's service bundle by a log
symbolic link.
A service and its associated log service may, where such convention is adhered to, be named together using shell brace expansion: {cyclog@,}
service-name.
chkservice /{run,var,etc}/service-bundles/{services,targets}/* /var/local/sv/*
Display the statuses of all (standard location) service bundles, in a full screen TUI scrollable table.
svstat /var/service-bundles/services/gcron
Print the status of the cron service, in human readable short form.
svstat --long /var/service-bundles/services/gcron
Print the status of the cron service, in human readable long form.
svc -u /var/service-bundles/services/gcron
Start the cron service, ignoring dependency and conflict information.
svc -d /var/service-bundles/services/gcron
Stop the cron service.
svc -o /var/service-bundles/services/gcron
Run the service at least once, starting it if it is not already started.
svc -O /var/service-bundles/services/gcron
Run the service at most once, not starting it if it is not already started.
svc -a /var/service-bundles/services/gcron
Send an ALRM
signal to the cron service.
This is used, for example, to tell logging services to cycle to a new log file.
svc -t /var/service-bundles/services/gcron
Send a TERM
signal to the cron service.
svc -T /var/service-bundles/services/gcron
Send a TERM

svc -k /var/service-bundles/services/gcron
Send a KILL
signal to the cron service.
svc -K /var/service-bundles/services/gcron
Send a KILL
signal to only the "main" process of the cron service.
svc -h /var/service-bundles/services/gcron
Send a HUP
signal to the cron service.
svc -H /var/service-bundles/services/gcron
Send a HUP
signal to only the "main" process of the cron service.
svshow /var/service-bundles/services/gcron
Emit a machine-parseable status of the cron service.
Use the --json
option for an alternative machine-parseable form.
rcctl get cron
Print the variables set by the conventional env/
environment directory for the cron service.
rcctl set cron flags --wibble
Set the flags
variable, set by the conventional env/ environment directory for the cron service, to --wibble
.
rcctl status cron

rcctl start cron
Start the cron service, following any dependencies.
rcctl stop cron
Stop the cron service.
rcctl enable cron
Set the cron service to auto-start at bootstrap.
rcctl disable cron
Set the cron service to not auto-start at bootstrap.

Print long form human-readable status of the cron service. This also prints the tail of any associated log, if it is in the conventional place.
system-control start cron
Start the cron service, following any dependencies.
system-control stop cron
Stop the cron service.
system-control preset cron
Set the cron service to auto-start at bootstrap or not, according to administrator-supplied and package-supplied preset information.
system-control reset cron
Start or stop the cron service according to its enable/disable state, i.e. reset to the configured bootstrap state.
system-control enable cron
Set the cron service to auto-start at bootstrap.
system-control disable cron
Set the cron service to not auto-start at bootstrap.
system-control condrestart cron
Send a TERM
signal to restart the cron service.
system-control hangup ttylogin@vc1-tty
Send a HUP
signal to the session leader/main process of the ttylogin@vc1-tty service.
system-control cat cron
Print the contents of the various run
, restart
, and so forth programs of the cron service.
system-control poweroff
Immediately run the system power-off procedure, shutting down any services configured to shut down at power off.
system-control print-service-env cron
Print the variables set by the conventional env/
environment directory for the cron service.
system-control set-service-env cron flags --wibble
Set the flags
variable, set by the conventional env/ environment directory for the cron service, to --wibble
.
svcadm enable cron
Start (sic!) the cron service.
svcadm disable cron
Stop (sic!) the cron service.
setfacl -m u:jim:rx /var/service-bundles/services/gcron{,/log}/supervise setfacl -m u:jim:rw /var/service-bundles/services/gcron{,/log}/supervise/ok setfacl -m u:jim:r /var/service-bundles/services/gcron{,/log}/supervise/status
On systems where these are not world-accessible, grant the user jim
access to read the status of the cron service and its associated log service.
shutdown -r -g 30
After a grace period of 30 minutes, during which messages will be broadcast to logged-on users, run the system reboot procedure, shutting down any services configured to shut down at power off.
