PKILL(1)			   BSD General Commands Manual				 PKILL(1)

NAME
     pkill -- find or signal processes by name

SYNOPSIS
     pgrep [-filnvx] [-d delim] [-G gid] [-g pgrp] [-P ppid] [-s sid] [-t tty] [-U uid] [-u euid]
	   pattern ...
     pkill [-signal] [-filnvx] [-G gid] [-g pgrp] [-P ppid] [-s sid] [-t tty] [-U uid] [-u euid]
	   pattern ...
     prenice [-l] priority 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 prenice command searches the process table on the running system and sets the priority
     of all processes that match the criteria given on the command line.

     The following options are available for pkill and pgrep:

     -d delim  Specify a delimiter to be printed between each process ID.  The default is a new-
	       line.  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.

     -i        Ignore case distinctions in both the process table and the supplied pattern.

     -l        Long output.  Print the process name in addition to the process ID for each match-
	       ing process.  If used in conjunction with -f, print the process ID and the full
	       argument list for each matching process.

     -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 com-
	       mand.

     -t tty    Restrict matches to processes associated with a terminal in the comma-separated
	       list tty.  Terminal names may be specified as a fully qualified path, in the form
	       'ttyXX', or 'pts/N', (where XX is any pair of letters, and N is a number), or the
	       shortened forms 'XX' or 'N'.  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.

     The -l flag is also availale for prenice.

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

EXIT STATUS
     pgrep, pkill, and prenice 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 NetBSD 1.6.  They are modelled after utilities of the same
     name that appeared in Sun Solaris 7.

     prenice was introduced in NetBSD 6.0.
