.Sh DESCRIPTION
|
|
The
|
|
.Nm 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.
|
|
.Pp
|
|
The
|
|
.Nm pkill
|
|
command searches the process table on the running system and signals all
|
|
processes that match the criteria given on the command line.
|
|
.Pp
|
|
The
|
|
.Nm 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.
|
|
.Pp
|
|
The following options are available for
|
|
.Nm pkill
|
|
and
|
|
.Nm pgrep :
|
|
.Bl -tag -width xxxxxxxx
|
|
.It Fl d Ar delim
|
|
Specify a delimiter to be printed between each process ID.
|
|
The default is a newline.
|
|
This option can only be used with the
|
|
.Nm pgrep
|
|
command.
|
|
.It Fl f
|
|
Match against full argument lists.
|
|
The default is to match against process names.
|
|
.It Fl G Ar gid
|
|
Restrict matches to processes with a real group ID in the comma-separated
|
|
list
|
|
.Ar gid .
|
|
.It Fl g Ar pgrp
|
|
Restrict matches to processes with a process group ID in the comma-separated
|
|
list
|
|
.Ar pgrp .
|
|
The value zero is taken to mean the process group ID of the running
|
|
.Nm pgrep
|
|
or
|
|
.Nm pkill
|
|
command.
|
|
.It Fl i
|
|
Ignore case distinctions in both the process table and the supplied pattern.
|
|
.It Fl l
|
|
Long output.
|
|
Print the process name in addition to the process ID for each matching
|
|
process.
|
|
If used in conjunction with
|
|
.Fl f ,
|
|
print the process ID and the full argument list for each matching process.
|
|
.It Fl n
|
|
Match only the most recently created process, if any.
|
|
.It Fl P Ar ppid
|
|
Restrict matches to processes with a parent process ID in the
|
|
comma-separated list
|
|
.Ar ppid .
|
|
.It Fl s Ar sid
|
|
Restrict matches to processes with a session ID in the comma-separated
|
|
list
|
|
.Ar sid .
|
|
The value zero is taken to mean the session ID of the running
|
|
.Nm pgrep
|
|
or
|
|
.Nm pkill
|
|
command.
|
|
.It Fl t Ar tty
|
|
Restrict matches to processes associated with a terminal in the
|
|
comma-separated list
|
|
.Ar tty .
|
|
Terminal names may be specified as a fully qualified path, in the form
|
|
.Sq ttyXX ,
|
|
or
|
|
.Sq pts/N ,
|
|
(where
|
|
.Ar XX
|
|
is any pair of letters, and
|
|
.Ar N
|
|
is a number),
|
|
or the shortened forms
|
|
.Sq XX
|
|
or
|
|
.Sq N .
|
|
A single dash
|
|
.Pq Sq -
|
|
matches processes not associated with a terminal.
|
|
.It Fl U Ar uid

|
.Fl f
|
|
is given.

The default is to match any substring.
|
|
.It Fl signal
|
|
A non-negative decimal number or symbolic signal name specifying the signal

|
.Pp
|
|
Note that a running
|
|
.Nm pgrep

.Nm pkill
|
|
process will never consider itself or system processes (kernel threads) as
|
|
a potential match.

.Nm pkill
|
|
and
|
|
.Nm pgrep

|
first appeared in
|
|
.Nx 1.6 .
|
|
They are modelled after utilities of the same name that appeared in Sun
