PGREP(1)                      Linux User's Manual                     PGREP(1)



NAME
       pgrep, pkill - look up or signal processes based on name and other attributes


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.)

       -n     Select only the newest (most recently started) of the matching processes.

       -o     Select only the oldest (least recently started) of the matching processes.

       -P ppid,...
              Only match processes whose parent process ID is listed.

       -s sid,...
              Only match processes whose process session ID is listed.  Session  ID  0  is
              translated into pgrep's or 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  numeri-
              cal 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 matching  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 processes:

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

       Example 4: Make all netscape processes run nicer:

       unix$ renice +4 'pgrep netscape'


EXIT STATUS
       0      One or more processes matched the criteria.

       1      No processes matched.

       2      Syntax error in the command line.

       3      Fatal error: out of memory etc.


NOTES
       The  process  name used for matching is limited to the 15 characters present in the
       output of /proc/pid/stat.  Use 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.
