.SH DESCRIPTION
.sp
.LP
The \fBpgrep\fR utility examines the active processes on the system and reports
the process \fBID\fRs of the processes whose attributes match the criteria
specified on the command line. Each process \fBID\fR is printed as a decimal
value and is separated from the next \fBID\fR by a delimiter string, which
defaults to a newline. For each attribute option, the user can specify a set of
possible values separated by commas on the command line. For example,
.sp
.in +2
.nf
\fBpgrep -G other,daemon\fR
.fi
.in -2
.sp

.sp
.LP
matches processes whose real group \fBID\fR is \fBother\fR \fBOR\fR
\fBdaemon\fR. If multiple criteria options are specified, \fBpgrep\fR matches
processes whose attributes match the logical \fBAND\fR of the criteria options.
For example,
.sp
.in +2
.nf
\fBpgrep -G other,daemon -U root,daemon\fR
.fi
.in -2
.sp

.sp
.LP
matches processes whose attributes are:
.br
.in +2
(real group \fBID\fR is \fBother\fR \fBOR\fR \fBdaemon\fR) \fBAND\fR
.in -2
.br
.in +2
(real user \fBID\fR is \fBroot\fR \fBOR\fR \fBdaemon\fR)
.in -2
.sp
.LP
\fBpkill\fR functions identically to \fBpgrep\fR, except that each matching
process is signaled as if by \fBkill\fR(1) instead of having its process
\fBID\fR printed. A signal name or number may be specified as the first command
line option to \fBpkill\fR.
.SH OPTIONS
.sp
.LP
The following options are supported:
.sp
.ne 2
.na
\fB\fB-c\fR \fIctidlist\fR\fR
.ad
.RS 17n
Matches only processes whose process contract ID is in the given list.
.RE

.sp
.ne 2
.na
\fB\fB-d\fR \fIdelim\fR\fR
.ad
.RS 17n
Specifies the output delimiter string to be printed between each matching
process \fBID\fR. If no \fB-d\fR option is specified, the default is a newline
character. The \fB-d\fR option is only valid when specified as an option to
\fBpgrep\fR.
.RE

.sp
.ne 2
.na
\fB\fB-f\fR\fR
.ad
.RS 17n
The regular expression \fIpattern\fR should be matched against the full process
argument string (obtained from the \fBpr_psargs\fR field of the
\fB/proc/\fInnnnn\fR/psinfo\fR file). If no \fB-f\fR option is specified, the
expression is matched only against the name of the executable file (obtained
from the \fBpr_fname\fR field of the \fB/proc/\fInnnnn\fR/psinfo\fR file).
.RE

.sp
.ne 2
.na
\fB\fB-g\fR \fIpgrplist\fR\fR
.ad
.RS 17n
Matches only processes whose process group \fBID\fR is in the given list. If
group 0 is included in the list, this is interpreted as the process group
\fBID\fR of the \fBpgrep\fR or \fBpkill\fR process.
.RE

.sp
.ne 2
.na
\fB\fB-G\fR \fIgidlist\fR\fR
.ad
.RS 17n
Matches only processes whose real group \fBID\fR is in the given list. Each
group \fBID\fR may be specified as either a group name or a numerical group
\fBID\fR.
.RE

.sp
.ne 2
.na
\fB\fB-J\fR \fIprojidlist\fR\fR
.ad
.RS 17n
Matches only processes whose project \fBID\fR is in the given list. Each
project \fBID\fR may be specified as either a project name or a numerical
project \fBID\fR.
.RE

.sp
.ne 2
.na
\fB\fB-l\fR\fR
.ad
.RS 17n
Long output format. Prints the process name along with the process \fBID\fR of
each matching process. The process name is obtained from the \fBpr_psargs\fR or
\fBpr_fname\fR field, depending on whether the \fB-f\fR option was specified
(see above). The \fB-l\fR option is only valid when specified as an option to
\fBpgrep\fR.
.RE

.sp
.ne 2
.na
\fB\fB-n\fR\fR
.ad
.RS 17n
Matches only the newest (most recently created) process that meets all other
specified matching criteria. Cannot be used with option \fB-o\fR.
.RE

.sp
.ne 2
.na
\fB\fB-o\fR\fR
.ad
.RS 17n
Matches only the oldest (earliest created) process that meets all other
specified matching criteria. Cannot be used with option \fB-n\fR.
.RE

.sp
.ne 2
.na
\fB\fB-P\fR \fIppidlist\fR\fR
.ad
.RS 17n
Matches only processes whose parent process \fBID\fR is in the given list.
.RE

.sp
.ne 2
.na
\fB\fB-s\fR \fIsidlist\fR\fR
.ad
.RS 17n
Matches only processes whose process session \fBID\fR is in in the given list.
If \fBID\fR 0 is included in the list, this is interpreted as the session
\fBID\fR of the \fBpgrep\fR or \fBpkill\fR process.
.RE

.sp
.ne 2
.na
\fB\fB-t\fR \fItermlist\fR\fR
.ad
.RS 17n
Matches only processes which are associated with a terminal in the given list.
Each terminal is specified as the suffix following "/dev/" of the terminal's
device path name in \fB/dev\fR. For example, \fBterm/a\fR or \fBpts/0\fR.
.RE

.sp
.ne 2
.na
\fB\fB-T\fR \fItaskidlist\fR\fR
.ad
.RS 17n
Matches only processes whose task \fBID\fR is in the given list. If \fBID\fR 0
is included in the list, this is interpreted as the task \fBID\fR of the
\fBpgrep\fR or \fBpkill\fR process.
.RE

.sp
.ne 2
.na
\fB\fB-u\fR \fIeuidlist\fR\fR
.ad
.RS 17n

\fBID\fR.
.RE

.sp
.ne 2
.na
\fB\fB-U\fR \fIuidlist\fR\fR
.ad
.RS 17n

\fBID\fR may be specified as either a login name or a numerical user \fBID\fR.
.RE

.sp
.ne 2
.na
\fB\fB-v\fR\fR
.ad
.RS 17n
Reverses the sense of the matching. Matches all processes \fBexcept\fR those
which meet the specified matching criteria.
.RE

.sp
.ne 2
.na
\fB\fB-x\fR\fR
.ad
.RS 17n
Considers only processes whose argument string or executable file name
\fBexactly\fR matches the specified \fIpattern\fR to be matching processes. The
pattern match is considered to be exact when all characters in the process
argument string or executable file name match the pattern.
.RE

.sp
.ne 2
.na
\fB\fB-z\fR \fIzoneidlist\fR\fR
.ad
.RS 17n
Matches only processes whose zone \fBID\fR is in the given list. Each zone
\fBID\fR may be specified as either a zone name or a numerical zone \fBID\fR.
This option is only useful when executed in the global zone. If the \fBpkill\fR
utility is used to send signals to processes in  other zones, the process must
have asserted the \fB{PRIV_PROC_ZONE}\fR privilege (see \fBprivileges\fR(5)).
.RE

.sp
.ne 2
.na
\fB\fB-\fR\fIsignal\fR\fR
.ad
.RS 17n
Specifies the signal to send to each matched process. If no signal is
specified, \fBSIGTERM\fR is sent by default. The value of \fIsignal\fR can be
one of the symbolic names defined in \fBsignal.h\fR(3HEAD) without the
\fBSIG\fR prefix, or the corresponding signal number as a decimal value. The
\fB-\fR\fIsignal\fR option is only valid when specified as the first option to
\fBpkill\fR.
.RE

.SH OPERANDS
.sp
.LP
The following operand is supported:
.sp
.ne 2
.na
\fB\fIpattern\fR\fR
.ad
.RS 11n
Specifies an Extended Regular Expression (\fBERE\fR) pattern to match against
either the executable file name or full process argument string. See
\fBregex\fR(5) for a complete description of the \fBERE\fR syntax.

.SH NOTES
.sp
.LP
Both utilities match the \fBERE\fR \fIpattern\fR argument against either the
\fBpr_fname\fR or \fBpr_psargs\fR fields of the
\fB/proc/\fR\fInnnnn\fR\fB/psinfo\fR files. The lengths of these strings are
limited according to definitions in \fB<sys/procfs.h>\fR\&. Patterns which can
match strings longer than the current limits may fail to match the intended set
of processes.
.sp
.LP
If the \fIpattern\fR argument contains \fBERE\fR meta-characters which are also
shell meta-characters, it may be necessary to enclose the pattern with
appropriate shell quotes.
.sp
.LP
Defunct processes are never matched by either \fBpgrep\fR or \fBpkill\fR.
.sp
.LP
The current \fBpgrep\fR or \fBpkill\fR process will never consider itself a
potential match.
