|

.Sh NAME
|
|
.Nm killall
|
|
.Nd kill processes by name
|
|
.Sh SYNOPSIS
|
|
.Nm
|
|
.Op Fl d | v
|
|
.Op Fl h | ?\&
|
|
.Op Fl help
|
|
.Op Fl l
|

|

|
|

|
|
.Op Fl SIGNAL
|
|
.Op Ar procname ...
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
utility kills processes selected by name, as opposed to the selection by pid
|
|
as done by
|
|
.Xr kill 1 .
|
|
By default, it will send a
|
|
.Dv TERM
|
|
signal to all processes with a real UID identical to the
|
|
caller of
|
|
.Nm
|
|
that match the name
|
|
.Ar procname .
|
|
The super-user is allowed to kill any process.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width 10n -offset indent
|
|
.It Fl d | v
|
|
Be more verbose about what will be done. For a single
|
|
.Fl d
|
|
option, a list of the processes that will be sent the signal will be
|
|
printed, or a message indicating that no matching processes have been
|
|
found.
|
|
.It Fl h | ?\&
|
|
.It Fl help
|
|
Give a help on the command usage and exit.
|
|
.It Fl l
|
|
List the names of the available signals and exit, like in
|
|
.Xr kill 1 .
|
|
.It Fl m
|
|
Match the argument
|
|
.Ar procname
|
|
as a (case insensitive) regular expression against the names
|
|
of processes found.
|
|
CAUTION! This is dangerous, a single dot will match any process
|
|
running under the real UID of the caller.
|
|
.It Fl s
|
|
Show only what would be done, but do not send any signal.
|
|
.It Fl SIGNAL
|
|
Send a different signal instead of the default
|
|
.Dv TERM .
|
|
The signal may be specified either as a name
|
|
(with or without a leading
|
|
.Dv SIG ) ,
|
|
or numerically.
|
|
.It Fl u Ar user
|
|
Limit potentially matching processes to those belonging to
|
|
the specified
|
|
.Ar user .
|
|
.It Fl t Ar tty
|
|
Limit potentially matching processes to those running on
|
|
the specified
|
|
.Ar tty .
|
|
.It Fl c Ar procname
|
|
When used with the
|
|
.Fl u
|
|
or
|
|
.Fl t
|
|
flags, limit potentially matching processes to those matching
|
|
the specified
|
|
.Ar procname .
|
|
.It Fl z
|
|
Do not skip zombies.
|
|
This should not have any effect except to print a few error messages
|
|
if there are zombie processes that match the specified pattern.
|
|
.El
|
|
.Sh ALL PROCESSES
|
|
Sending a signal to all processes with uid
|
|
.Em XYZ
|
|
is already supported by
|
|
.Xr kill 1 .
|
|
So use
|
|
.Xr kill 1
|
|
for this job (e.g. $ kill -TERM -1 or
|
|
as root $ echo kill -TERM -1 | su -m <user>)
|
|
.Sh DIAGNOSTICS
|
|
The
|
|
.Nm
|
|
command will respond with a short usage message and exit with a status
|
|
of 2 in case of a command error. A status of 1 will be returned if
|
|
either no matching process has been found or not all processes have
|
|
been signalled successfully. Otherwise, a status of 0 will be
|
|
returned.
|
|
.Pp
|
|
Diagnostic messages will only be printed if requested by
|
|
.Fl d
|
|
options.
