.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 following options are available:
|
|
.Bl -tag -width ".Fl F Ar pidfile"
|
|
.It Fl F Ar pidfile
|
|
Restrict matches to a process whose PID is stored in the
|
|
.Ar pidfile
|
|
file.
|
|
.It Fl G Ar gid
|
|
Restrict matches to processes with a real group ID in the comma-separated
|
|
list
|
|
.Ar gid .
|
|
.It Fl I
|
|
Request confirmation before attempting to kill each process.
|
|
.It Fl L
|
|
The
|
|
.Ar pidfile
|
|
file given for the
|
|
.Fl F
|
|
option must be locked with the
|
|
.Xr flock 2
|
|
syscall or created with
|
|
.Xr pidfile 3 .
|
|
.It Fl M Ar core
|
|
Extract values associated with the name list from the specified core
|
|
instead of the currently running system.
|
|
.It Fl N Ar system
|
|
Extract the name list from the specified system instead of the default,
|
|
which is the kernel image the system has booted from.
|
|
.It Fl P Ar ppid
|
|
Restrict matches to processes with a parent process ID in the
|
|
comma-separated list
|
|
.Ar ppid .
|
|
.It Fl S
|
|
Search also in system processes (kernel threads).
|
|
.It Fl U Ar uid
|
|
Restrict matches to processes with a real user ID in the comma-separated
|
|
list
|
|
.Ar uid .
|
|
.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 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 j Ar jid
|
|
Restrict matches to processes inside jails with a jail ID in the comma-separated
|
|
list
|
|
.Ar jid .
|
|
The value zero is taken to mean any jail ID.
|
|
.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.
|
|
This option can only be used with the
|
|
.Nm pgrep
|
|
command.
|
|
.It Fl n
|
|
Select only the newest (most recently started) of the matching processes.
|
|
.It Fl o
|
|
Select only the oldest (least recently started) of the matching processes.
|
|
.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 of the form
|
|
.Pa tty Ns Ar xx
|
|
or the shortened form
|
|
.Ar xx .
|
|
A single dash
|
|
.Pq Ql -
|
|
matches processes not associated with a terminal.
|
|
.It Fl u Ar euid
|
|
Restrict matches to processes with an effective user ID in the
|
|
comma-separated list
|
|
.Ar euid .
|
|
.It Fl v
|
|
Reverse the sense of the matching; display processes that do not match the
|
|
given criteria.
|
|
.It Fl x
|
|
Require an exact match of the process name, or argument list if
|
|
.Fl f
|
|
is given.
|
|
The default is to match any substring.
|
|
.It Fl Ns Ar signal
|
|
A non-negative decimal number or symbolic signal name specifying the signal
|
|
to be sent instead of the default
|
|
.Dv TERM .
|
|
This option is valid only when given as the first argument to
|
|
.Nm pkill .
|
|
.El
|
|
.Pp
|
|
If any
|
|
.Ar pattern
|
|
operands are specified, they are used as regular expressions to match
|
|
the command name or full argument list of each process.
|
|
If the
|
|
.Fl f
|
|
option is not specified, then the
|
|
.Ar pattern
|
|
will attempt to match the command name.
|
|
However, presently
|
|
.Fx
|
|
will only keep track of the first 19 characters of the command
|
|
name for each process.
|
|
Attempts to match any characters after the first 19 of a command name
|
|
will quietly fail.
|
|
.Pp
|
|
Note that a running
|
|
.Nm pgrep
|
|
or
|
|
.Nm pkill
|
|
process will never consider itself nor system processes (kernel threads) as
|
|
a potential match.
|
|
.Sh EXIT STATUS
|
|

|
|
.Nm pgrep
|
|
and
|
|
.Nm pkill
|
|
utilities
|
|
return one of the following values upon exit:
|
|
.Bl -tag -width indent
