Service management cheatsheet

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, /service/cron.

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.

Daemontools-style

```
svstat /service/cron
```
Print the status of the cron service, in human readable short form.
```
svstat --long /service/cron
```
Print the status of the cron service, in human readable long form.
```
svc -u /service/cron
```
Start the cron service, ignoring dependency and conflict information.
```
svc -d /service/cron
```
Stop the cron service.
```
svc -o /service/cron
```
Run the service at least once, starting it if it is not already started.
```
svc -O /service/cron
```
Run the service at most once, not starting it if it is not already started.
```
svc -a /service/cron
```
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 /service/cron
```
Send a TERM signal to the cron service.
```
svc -T /service/cron
```
Send a TERM signal to only the "main" process of the cron service.
```
svc -k /service/cron
```
Send a KILL signal to the cron service.
```
svc -K /service/cron
```
Send a KILL signal to only the "main" process of the cron service.
```
svc -h /service/cron
```
Send a HUP signal to the cron service.
```
svc -H /service/cron
```
Send a HUP signal to only the "main" process of the cron service.
```
svshow /service/cron
```
Emit a machine-parseable status of the cron service. Use the --json option for an alternative machine-parseable form.

OpenBSD-style

```
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
```
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.
```
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.

systemd-style

```
system-control status cron
```
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.

Solaris SMF-style

```
svcadm enable cron
```
Set the cron service to auto-start at bootstrap.
```
svcadm disable cron
```
Set the cron service to not auto-start at bootstrap.

Common

setfacl -m u:jim:rx /service/cron{,/log}/supervise
setfacl -m u:jim:rw /service/cron{,/log}/supervise/ok
setfacl -m u:jim:r /service/cron{,/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.
