If the service is parameterized, requires the + same arguments used for enabling, to disable the specific instance of the + service. + * dumpscript - generate an equivalent shell script from the `exec` lines of + a service after applying all parameter substitutions. + * list - list all enabled service. A target can be specified to only list + services for the specified target. + * help - display a short help text and a list of available commands. + + +## shutdown and reboot + +The programs `shudown` and `reboot` can be used to signal to the `init` program +that it should transition to the `shutdown` or `reboot` target respectively. + +The option `-f` or `--force` can be used to by pass the init system entirely +and force a hard reset or power off by directly signalling the kernel. + +Running any one of those programs requires superuser privileges. + + +## syslog + +If the `usyslogd` service is built as part of this package, a program called +`syslog` is built that can be used from the command line to send syslog +messages. + +This can for instance be used to produce log messages from shell scripts. + +The log level, facility and identity string can be specified. +See `syslog --help` for more information. |
