DESCRIPTION

       The  pgrep utility examines the active processes on the system and reports the process IDs of the processes whose attributes match the cri-
       teria specified on the command line. Each process ID is printed as a decimal value and is separated from the next ID 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,

	 pgrep -G other,daemon

       matches processes whose real group ID is other OR daemon. If multiple  criteria	options  are  specified,  pgrep  matches  processes  whose
       attributes match the logical AND of the criteria options. For example,

	 pgrep -G other,daemon -U root,daemon

       matches processes whose attributes are:
	 (real group ID is other OR daemon) AND
	 (real user ID is root OR daemon)

       pkill  functions  identically  to  pgrep,  except  that each matching process is signaled as if by kill(1) instead of having its process ID
       printed. A signal name or number may be specified as the first command line option to pkill.

OPTIONS

       The following options are supported:

       -c ctidlist	Matches only processes whose process contract ID is in the given list.

       -d delim 	Specifies the output delimiter string to be printed between each matching process ID. If no -d option  is  specified,  the
			default is a newline character. The -d option is only valid when specified as an option to pgrep.

       -f		The  regular  expression  pattern  should be matched against the full process argument string (obtained from the pr_psargs
			field of the /proc/nnnnn/psinfo file). If no -f option is specified, the expression is matched only against  the  name	of
			the executable file (obtained from the pr_fname field of the /proc/nnnnn/psinfo file).

       -g pgrplist	Matches  only  processes  whose  process group ID is in the given list. If group 0 is included in the list, this is inter-
			preted as the process group ID of the pgrep or pkill process.

       -G gidlist	Matches only processes whose real group ID is in the given list. Each group ID may be specified as either a group name	or
			a numerical group ID.

       -J projidlist	Matches only processes whose project ID is in the given list. Each project ID may be specified as either a project name or
			a numerical project ID.

       -l		Long output format. Prints the process name along with the process ID of  each	matching  process.  The  process  name	is
			obtained from the pr_psargs or pr_fname field, depending on whether the -f option was specified (see above). The -l option
			is only valid when specified as an option to pgrep.

       -n		Matches only the newest (most recently created) process that meets all other specified matching criteria. Cannot  be  used
			with option -o.

       -o		Matches  only  the oldest (earliest created) process that meets all other specified matching criteria. Cannot be used with
			option -n.

       -P ppidlist	Matches only processes whose parent process ID is in the given list.

       -s sidlist	Matches only processes whose process session ID is in in the given list. If ID 0 is included in the list, this	is  inter-
			preted as the session ID of the pgrep or pkill process.

       -t termlist	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 /dev. For example, term/a or pts/0.

       -T taskidlist	Matches only processes whose task ID is in the given list. If ID 0 is included in the list, this  is  interpreted  as  the
			task ID of the pgrep or pkill process.

       -u euidlist	Matches  only processes whose effective user ID is in the given list. Each user ID may be specified as either a login name
			or a numerical user ID.

       -U uidlist	Matches only processes whose real user ID is in the given list. Each user ID may be specified as either a login name or  a
			numerical user ID.

       -v		Reverses the sense of the matching. Matches all processes except those which meet the specified matching criteria.

       -x		Considers  only processes whose argument string or executable file name exactly matches the specified pattern to be match-
			ing processes. The pattern match is considered to be exact when all characters in the  process	argument  string  or  exe-
			cutable file name match the pattern.

       -z zoneidlist	Matches only processes whose zone ID is in the given list. Each zone ID may be specified as either a zone name or a numer-
			ical zone ID. This option is only useful when executed in the global zone. If the pkill utility is used to send signals to
			processes in  other zones, the process must have asserted the {PRIV_PROC_ZONE} privilege (see privileges(5)).

       -signal		Specifies  the signal to send to each matched process. If no signal is specified, SIGTERM is sent by default. The value of
			signal can be one of the symbolic names defined in signal.h(3HEAD) without the SIG prefix,  or	the  corresponding  signal
			number as a decimal value. The -signal option is only valid when specified as the first option to pkill.

OPERANDS

       The following operand is supported:

       pattern	  Specifies an Extended Regular Expression (ERE) pattern to match against either the executable file name or full process argument
		  string. See regex(5) for a complete description of the ERE syntax.

EXAMPLES

       Example 1 Obtaining a Process ID

       Obtain the process ID of sendmail:

	 example% pgrep -x -u root sendmail
	 283

       Example 2 Terminating a Process

       Terminate the most recently created xterm:

	 example% pkill -n xterm

EXIT STATUS

       The following exit values are returned:

       0    One or more processes were matched.

       1    No processes were matched.

       2    Invalid command line options were specified.

       3    A fatal error occurred.

FILES

NOTES

       Both utilities match the ERE pattern argument against either the pr_fname or pr_psargs fields of the /proc/nnnnn/psinfo files. The  lengths
       of  these  strings  are limited according to definitions in <sys/procfs.h>. Patterns which can match strings longer than the current limits
       may fail to match the intended set of processes.

       If the pattern argument contains ERE meta-characters which are also shell meta-characters, it may be necessary to enclose the pattern  with
       appropriate shell quotes.

       Defunct processes are never matched by either pgrep or pkill.

       The current pgrep or pkill process will never consider itself a potential match.
