pgrep




SYNOPSIS

       pgrep [-flvx] [-d delimiter]  [-n|-o]  [-P  ppid,...]  [-g
       pgrp,...]
            [-s  sid,...] [-u euid,...] [-U uid,...] [-G gid,...]
            [-t term,...] [pattern]

       pkill [-signal] [-fvx] [-n|-o] [-P ppid,...] [-g pgrp,...]
            [-s  sid,...] [-u euid,...] [-U uid,...] [-G gid,...]
            [-t term,...] [pattern]


DESCRIPTION

       pgrep looks through the currently  running  processes  and
       lists the process IDs which matches the selection criteria
       to stdout.  All the criteria have to match.  For example,

       pgrep -u root sshd

       will only list the processes  called  sshd  AND  owned  by
       root.  On the other hand,

       pgrep -u root,daemon

       will list the processes owned by root OR daemon.

       pkill  will send the specified signal (by default SIGTERM)
       to each process instead of listing them on stdout.


OPTIONS

       -d delimiter
              Sets the string used to delimit each process ID  in
              the output (by default a newline).  (pgrep only.)

       -f     The  pattern  is  normally only matched against the
              process name.  When -f is  set,  the  full  command
              line is used.

       -g pgrp,...
              Only  match  processes  in  the  process  group IDs
              listed.  Process group 0 is translated into pgrep's
              or pkill's own process group.

       -G gid,...
              Only match processes whose real group ID is listed.
              Either the numerical or  symbolical  value  may  be
              used.

       -l     List  the  process  name as well as the process ID.
              (pgrep only.)
              pkill's own session ID.

       -t term,...
              Only  match processes whose controlling terminal is
              listed.  The  terminal  name  should  be  specified
              without the "/dev/" prefix.

       -u euid,...
              Only  match  processes  whose  effective user ID is
              listed.  Either the numerical or  symbolical  value
              may be used.

       -U uid,...
              Only  match processes whose real user ID is listed.
              Either the numerical or  symbolical  value  may  be
              used.

       -v     Negates the matching.

       -x     Only match processes whose name (or command line if
              -f is specified) exactly match the pattern.

       -signal
              Defines the signal to send to each matched process.
              Either  the numeric or the symbolic signal name can
              be used.  (pkill only.)


OPERANDS

       pattern
              Specifies an Extended Regular Expression for match­
              ing against the process names or command lines.


EXAMPLES

       Example 1: Find the process ID of the named daemon:

       unix$ pgrep -u root named

       Example 2: Make syslog reread its configuration file:

       unix$ pkill -HUP syslogd

       Example  3:  Give  detailed  information on all xterm pro­
       cesses:

       unix$ ps -fp $(pgrep -d, -x xterm)

       Example 4: Make all netscape processes run nicer:

       unix$ renice +4 `pgrep netscape`

       the -f option to match against the complete command  line,
       /proc/pid/cmdline.

       The  running  pgrep  or  pkill  process  will never report
       itself as a match.


BUGS

       The options -n and -o and -v can not be combined.  Let  me
       know if you need to do this.

       Defunct processes are reported.

STANDARDS

       pkill  and pgrep were introduced in Sun's Solaris 7.  This
       implementation is fully compatible.
