.Ar command
.Sh DESCRIPTION
The
.Nm
command is an easy interface to the rc.d system.
Its primary purpose is to start and stop services provided
by the rc.d scripts.
When used for this purpose it will set the same restricted
environment that is in use at boot time
.Po
see
.Sx ENVIRONMENT
.Pc .
It can also be used to list
the scripts using various criteria.
.Pp
The options are as follows:
.Bl -tag -width F1
.It Fl e
List services that are enabled.
The list of scripts to check is compiled using
.Xr rcorder 8
the same way that it is done in
.Xr rc 8 ,
then that list of scripts is checked for an
.Qq rcvar
assignment.
If present the script is checked to see if it is enabled.
.It Fl j Ar jail
Perform the given actions under the named jail.
The
.Ar jail
argument can be either a jail ID or a jail name.
.It Fl l
List all files in
.Pa /etc/rc.d
and the local startup directories.
As described in
.Xr rc.conf 5
this is usually
.Pa /usr/local/etc/rc.d .
All files will be listed whether they are an actual
rc.d script or not.
.It Fl R
Restart all enabled local services.
.It Fl r
Generate the
.Xr rcorder 8
as in
.Fl e
above, but list all of the files, not just what is enabled.
.It Fl v
Be slightly more verbose.
.El
.Sh ENVIRONMENT
When used to run rc.d scripts the
.Nm
command sets
.Ev HOME
to
.Pa /
and
.Ev PATH
to
.Pa /sbin:/bin:/usr/sbin:/usr/bin
which is how they are set in
.Pa /etc/rc
at boot time.
.Sh EXIT STATUS
.Ex -std
.Sh EXAMPLES
The following are examples of typical usage of the
.Nm
command:
.Bd -literal -offset -ident
service named status
service -j dns named status
service -rv
.Ed
.Pp
The following programmable completion entry can be used in
.Xr bash 1
for the names of the rc.d scripts:
.Bd -literal -offset -ident
_service () {
	local cur
	cur=${COMP_WORDS[COMP_CWORD]}
	COMPREPLY=( $( compgen -W '$( service -l )' -- $cur ) )
	return 0
}
complete -F _service service
