.SH DESCRIPTION
.sp
.LP
The \fBsvcs\fR command displays information about service instances as recorded
in the service configuration repository.
.sp
.LP
The first form of this command prints one-line status listings for service
instances specified by the arguments. Each instance is listed only once. With
no arguments, all enabled service instances, even if temporarily disabled, are
listed with the columns indicated below.
.sp
.LP
The second form prints one-line status listings for the dependencies or
dependents of the service instances specified by the arguments.
.sp
.LP
The third form prints detailed information about specific services and
instances.
.sp
.LP
The fourth form explains the states of service instances. For each argument, a
block of human-readable text is displayed which explains what state the service
is in, and why it is in that state. With no arguments, problematic services are
described.
.sp
.LP
Error messages are printed to the standard error stream.
.sp
.LP
The output of this command can be used appropriately as input to the
\fBsvcadm\fR(1M) command.

.RS 20n
(The letter ell.) Displays all available information about the selected
services and service instances, with one service attribute displayed for each
line. Information for different instances are separated by blank lines.
.sp
The following specific attributes require further explanation:
.sp
.ne 2
.na
\fB\fBdependency\fR\fR
.ad
.RS 14n
Information about a dependency. The grouping and \fBrestart_on\fR properties
are displayed first and are separated by a forward slash (\fB/\fR). Next, each
entity and its state is listed. See \fBsmf\fR(5) for information about states.
In addition to the standard states, each service dependency can have the
following state descriptions:
.sp
.ne 2
.na
\fB\fBabsent\fR\fR
.ad
.RS 12n
No such service is defined on the system.
.RE

.sp
.ne 2
.na
\fB\fBinvalid\fR\fR
.ad
.RS 12n
The fault management resource identifier (FMRI) is invalid (see \fBsmf\fR(5)).
.RE

.sp
.ne 2
.na
\fB\fBmultiple\fR\fR
.ad

\fB\fBonline\fR\fR
.ad
.RS 11n

.ad
.RS 11n

temporarily (until the next system reboot). The former is specified as either
\fBtrue\fR or \fBfalse\fR, and the latter is designated by the presence of
\fB(temporary)\fR.
.sp
A service might be temporarily disabled because an administrator has run
\fBsvcadm disable -t\fR, used \fBsvcadm milestone\fR, or booted the system to a
specific milestone. See \fBsvcadm\fR(1M) for details.

.SH OPERANDS
.sp
.LP
The following operands are supported:
.sp
.ne 2
.na
\fB\fIFMRI\fR\fR
.ad
.RS 17n
A fault management resource identifier (FMRI) that specifies one or more
instances (see \fBsmf\fR(5)). FMRIs can be abbreviated by specifying the
instance name, or the trailing portion of the service name. For example, given
the FMRI:
.sp
.in +2
.nf
svc:/network/smtp:sendmail
.fi
.in -2
.sp

The following are valid abbreviations:
.sp
.in +2
.nf
sendmail
:sendmail
smtp
smtp:sendmail
network/smtp
.fi
.in -2
.sp

The following are invalid abbreviations:
.sp
.in +2
.nf
mail
network
network/smt
.fi
.in -2
.sp

If the FMRI specifies a service, then the command applies to all instances of
that service, except when used with the \fB-D\fR option.
.sp
Abbreviated forms of FMRIs are unstable, and should not be used in scripts or
other permanent tools.
.RE

.sp
.ne 2
.na
\fB\fIpattern\fR\fR
.ad
.RS 17n
A pattern that is matched against the \fIFMRI\fRs of service instances
according to the "globbing" rules described by \fBfnmatch\fR(5). If the pattern
does not begin with \fBsvc:\fR, then \fBsvc:/\fR is prepended. The following is
a typical example of a glob pattern:
.sp
.in +2
.nf

.sp
.LP
(a) In this example, \fBsvcs\fR \fB-x\fR has identified that the print/server
service being disabled is the root cause of two services which are enabled but
not online. \fBsvcs\fR \fB-xv\fR shows that those services are
\fBprint/rfc1179\fR and \fBprint/ipp-listener\fR. This situation can be
rectified by either enabling \fBprint/server\fR or disabling \fBrfc1179\fR and
\fBipp-listener\fR.
