.Sh DESCRIPTION
The
.Nm
utility can enable or disable a base system
.Ar service
or a base system or package
.Ar daemon
in
.Xr rc.conf.local 8
or display its configuration and status.
For a
.Ar daemon ,
it can also change the command line arguments, the user to run as, the
.Xr rc.d 8
action timeout or call its
.Xr rc.d 8
.Ar daemon
control script.
.Pp
The following commands are available
.Po
.Ar variable
can be one of
.Cm class ,
.Cm flags ,
.Cm logger ,
.Cm status ,
.Cm timeout
or
.Cm user
.Pc :
.Bl -tag -width Ds
.It Oo Fl df Oc Ar action daemon ...
Run the
.Xr rc.d 8
.Ar daemon
scripts with the
.Ar action
argument, passing through the specified options, if any.
.It Cm disable Ar service ... | daemon ...
Alias for
.Cm set Ar service Ns | Ns Ar daemon Cm status off .
.It Cm enable Ar service ... | daemon ...
Alias for
.Cm set Ar service Ns | Ns Ar daemon Cm status on .
.It Cm get Ar service | daemon Op Ar variable
Display the value of
.Ar service
or
.Ar daemon Ns _ Ns Ar variable .
If
.Ar variable
is empty, display all
.Ar service
or
.Ar daemon
variables and values in a format
compatible with
.Xr rc.conf 8 .
When
.Ar daemon
is set to
.Qq all ,
.Ar variable
must not be set and
.Nm
will display all services and daemons variables.
.It Cm getdef Ar service | daemon Op Ar variable
Like
.Cm get
but returns the default values.
.It Cm ls Ar lsarg
Display a list of services and daemons matching
.Ar lsarg ,
which can be one of:
.Pp
.Bl -tag -width stopped -offset indent -compact
.It Cm all
all services and daemons
.It Cm failed
enabled but stopped daemons
.It Cm off
disabled services and daemons
.It Cm on
enabled services and daemons
.It Cm rogue
daemons which are disabled but currently running
.It Cm started
running daemons
.It Cm stopped
stopped daemons
.El
.It Cm order Op Ar daemon ...
Move the specified package daemons to the beginning of
.Va pkg_scripts .
They need to be already enabled.
If no
.Ar daemon
is specified, display the current order.
.Pp
The
.Cm order
command is only needed after enabling a new daemon
that needs to run before one or more already enabled daemons.
Specify the new daemon preceded by all that need to run before it,
but not the ones depending on it.
.It Cm set Ar service | daemon variable Op Ar arguments
For a daemon, set the variable
.Ar daemon Ns _ Ns Ar variable
to the specified
.Ar arguments .
If
.Ar variable
is already set,
.Ar daemon Ns _ Ns Ar variable
is reset to the optionally provided
.Ar arguments
or to its default value.
.Pp
The
.Cm status
.Ar variable
must be provided with the
.Cm on
or
.Cm off
.Ar arguments .
It is used to enable or disable
.Ar service
or
.Ar daemon
in
.Xr rc.conf.local 8 .
When a disabled package daemon is enabled, it is appended to the end of
.Va pkg_scripts .
When a package daemon is disabled, it is removed from
.Va pkg_scripts
and its variables are removed if any.
.El
.Sh EXIT STATUS
.Nm Ar action
returns with the exit status of the
.Xr rc.d 8
.Ar daemon
script.
.Nm Cm get Ar daemon | service Op Cm status
exits with 0 if the daemon or service is enabled and 1 if it is not.
.Nm Cm getdef Ar daemon | service Op Cm status
exits with 0 if the daemon or service is enabled by default
and 1 if it is not.
.Nm Cm ls failed
exits with 1 if an enabled daemon is not running.
Otherwise, the
.Nm
utility exits with 0 on success, and >0 if an error occurs
.Po 2 indicates a non-existent
.Ar daemon | service
.Pc .
.Sh EXAMPLES
Enable and set
.Xr apmd 8
flags:
.Bd -literal -offset indent
# rcctl set apmd status on
# rcctl set apmd flags -A
# rcctl get apmd
apmd_class=daemon
apmd_flags=-A
apmd_logger=
apmd_rtable=0
apmd_timeout=30
apmd_user=root
# echo $?
0
.Ed
.Pp
The recommended way to run a second copy of a given daemon for a
different purpose is to create a symbolic link to its
.Xr rc.d 8
control script:
.Bd -literal -offset indent
# ln -s /etc/rc.d/snmpd /etc/rc.d/snmpd6
# rcctl set snmpd6 status on
# rcctl set snmpd6 flags -D addr=2001:db8::1234
# rcctl start snmpd6
