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 Ar var=value +Set the environment variable +.Ar var +to the specified +.Ar value +before starting the script. +This option can be used multiple times. .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. +If the +.Fl E +option is used, the corresponding variable is set accordingly. .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 -E LC_ALL=C.UTF-8 named start service -rv .Ed .Pp The following programmable completion entry can be used in .Xr csh 1 for the names and common commands of the rc.d scripts: .Bd -literal -offset indent complete service 'c/-/(e l r v)/' 'p/1/`service -l`/' \e 'n/*/(start stop reload restart \e status rcvar onestart onestop)/' .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 .Ed .Sh SEE ALSO .Xr bash 1 Pq Pa ports/shells/bash , .Xr rc.conf 5 , .Xr rc 8 , .Xr rcorder 8 .Sh HISTORY The .Nm utility first appeared in .Fx 7.3 . .Sh AUTHORS This manual page was written by .An Douglas Barton Aq Mt dougb@FreeBSD.org . diff --git a/usr.sbin/service/service.sh b/usr.sbin/service/service.sh index f056c43d3c98..5f232955bdff 100755 --- a/usr.sbin/service/service.sh +++ b/usr.sbin/service/service.sh @@ -1,181 +1,186 @@ #!/bin/sh # $FreeBSD$ # SPDX-License-Identifier: BSD-2-Clause # # Copyright (c) 2009 Douglas Barton # All rights reserved. # # Redistribution and use in source and binary forms, with or without # modification, are permitted provided that the following conditions # are met: # 1.
