+.Dt KILLALL 1
+.Sh NAME
+.Nm killall
+.Nd kill processes by name
+.Sh SYNOPSIS
+.Nm
+.Op Fl delmsvz
+.Op Fl help
+.Op Fl u Ar user
+.Op Fl t Ar tty
+.Op Fl c Ar procname
+.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 v
+Be more verbose about what will be done.
+.It Fl e
+Use the effective user ID instead of the (default) real user ID for matching
+processes specified with the
+.Fl u
+option.
+.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 sensitive) 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 d
+Print detailed information about the processes matched,
+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 EXIT STATUS
+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.
+.Sh DIAGNOSTICS
+Diagnostic messages will only be printed if requested by
+.Fl d
+options.
+.Sh SEE ALSO
+.Xr kill 1 ,
+.Xr sysctl 3
+.Sh HISTORY
+The
+.Nm
+command appeared in
+.Fx 2.1 .
+It has been modeled after the
+.Nm
+command as available on other platforms.
+.Sh AUTHORS
+.An -nosplit
+The
+.Nm
+program was originally written in Perl and was contributed by
+.An Wolfram Schneider ,
+this manual page has been written by
+.An J\(:org Wunsch .
+The current version of
+.Nm
+was rewritten in C by
+.An Peter Wemm
+using
+.Xr sysctl 3 .
