Avoid using parenthesis enclosure macros (.Pq and .Po/.Pc) with plain text. Not only this slows down the mdoc(7) processing significantly, but it also has an undesired (in this case) effect of disabling hyphenation within the entire enclosed block.

.Dt KILLALL 1
|
|
.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 m
|
|
.Op Fl s
|
|
.Op Fl u Ar user
|
|
.Op Fl t Ar tty
|

|
|
.Op Fl SIGNAL
|
|
.Op Ar procname ...
|
|
.Sh DESCRIPTION
|
|
.Nm Killall
|
|
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 an effective 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 effective 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 progname .
|
|
.El
|
|
.Sh ALL PROCESSES
|
|
Sending a signal to all processes with uid
|
|
.Nm 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.
