PKILL(1)                     BSD Reference Manual                     PKILL(1)

NAME

     pgrep, pkill - find or signal processes by name

SYNOPSIS

     pgrep [-flnvx] [-d delim] [-G gid] [-g pgrp] [-P ppid] [-s sid] [-t tty]
           [-U uid] [-u euid] [pattern ...]
     pkill [-signal] [-fnvx] [-G gid] [-g pgrp] [-P ppid] [-s sid] [-t tty]
           [-U uid] [-u euid] [pattern ...]

DESCRIPTION

     The pgrep command searches the process table on the running system and
     prints the process IDs of all processes that match the criteria given on
     the command line.

     The pkill command searches the process table on the running system and
     signals all processes that match the criteria given on the command line.

     The following options are available:

     -d delim
             Specify a delimiter to be printed between each process ID. The
             default is a newline. This option can only be used with the pgrep
             command.

     -f      Match against full argument lists. The default is to match
             against process names.

     -G gid  Restrict matches to processes with a real group ID in the comma-
             separated list gid.

     -g pgrp
             Restrict matches to processes with a process group ID in the
             comma-separated list pgrp. The value zero is taken to mean the
             process group ID of the running pgrep or pkill command.

     -l      Long output. Print the process name in addition to the process ID
             for each matching process. If used in conjunction with -f, print
             the process ID and the full argument list for each matching pro-
             cess. This option can only be used with the pgrep command.

     -n      Match only the most recently created process, if any.

     -P ppid
             Restrict matches to processes with a parent process ID in the
             comma-separated list ppid.

     -s sid  Restrict matches to processes with a session ID in the comma-
             separated list sid. The value zero is taken to mean the session
             ID of the running pgrep or pkill command.

     -t tty  Restrict matches to processes associated with a terminal in the
             comma-separated list tty. Terminal names may be of the form
             'ttyxx' or the shortened form 'xx'. A single dash ('-') matches
             processes not associated with a terminal.

     -U uid  Restrict matches to processes with a real user ID in the comma-
             separated list uid.

     -u euid
             Restrict matches to processes with an effective user ID in the
             comma-separated list euid.

     -v      Reverse the sense of the matching; display processes that do not
             match the given criteria.
     -x      Require an exact match of the process name, or argument list if
             -f is given. The default is to match any substring.

     -signal
             A non-negative decimal number or symbolic signal name specifying
             the signal to be sent instead of the default TERM. This option is
             valid only when given as the first argument to pkill.

     Note that a running pgrep or pkill process will never consider itself or
     system processes (kernel threads) as a potential match.

     pgrep and pkill return one of the following values upon exit:

           0       One or more processes were matched.
           1       No processes were matched.
           2       Invalid options were specified on the command line.
           3       An internal error occurred.

HISTORY

     pkill and pgrep first appeared in OpenBSD 3.5. They are modelled after
     utilities of the same name that appeared in Sun Solaris 7.
