29.Dt KILLALL 1
30.Sh NAME
31.Nm killall
32.Nd kill processes by name
33.Sh SYNOPSIS
34.Nm
35.Op Fl d | v
36.Op Fl h | ?\&
37.Op Fl help
38.Op Fl l
39.Op Fl m
40.Op Fl s
41.Op Fl u Ar user
42.Op Fl t Ar tty
43.Op Fl c Ar procname
44.Op Fl SIGNAL
45.Op Ar procname ...
46.Sh DESCRIPTION
47.Nm Killall
48kills processes selected by name, as opposed to the selection by pid
49as done by
50.Xr kill 1 .
51By default, it will send a
52.Dv TERM
53signal to all processes with an effective UID identical to the
54caller of
55.Nm
56that match the name
57.Ar procname .
58The super-user is allowed to kill any process.
59.Pp
60The options are as follows:
61.Bl -tag -width 10n -offset indent
62.It Fl d | v
63Be more verbose about what will be done.  For a single
64.Fl d
65option, a list of the processes that will be sent the signal will be
66printed, or a message indicating that no matching processes have been
67found.
68.It Fl h | ?\&
69.It Fl help
70Give a help on the command usage and exit.
71.It Fl l
72List the names of the available signals and exit, like in
73.Xr kill 1 .
74.It Fl m
75Match the argument
76.Ar procname
77as a (case insensitive) regular expression against the names
78of processes found.
79CAUTION!  This is dangerous, a single dot will match any process
80running under the effective UID of the caller.
81.It Fl s
82Show only what would be done, but do not send any signal.
83.It Fl SIGNAL
84Send a different signal instead of the default
85.Dv TERM .
86The signal may be specified either as a name
87.Pq with \&or without a leading Dv SIG ,
88or numerically.
89.It Fl u Ar user
90Limit potentially matching processes to those belonging to
91the specified
92.Ar user .
93.It Fl t Ar tty
94Limit potentially matching processes to those running on
95the specified
96.Ar tty .
97.It Fl c Ar procname
98When used with the
99.Fl u
100or
101.Fl t
102flags, limit potentially matching processes to those matching
103the specified
104.Ar progname .
105.El
106.Sh ALL PROCESSES
107Sending a signal to all processes with uid
108.Nm XYZ
109is already supported by
110.Xr kill 1 .
111So use
112.Xr kill 1
113for this job (e.g. $ kill -TERM -1 or
114as root $ echo kill -TERM -1 | su -m <user>)
115.Sh DIAGNOSTICS
116The
117.Nm
118command will respond with a short usage message and exit with a status
119of 2 in case of a command error.  A status of 1 will be returned if
120either no matching process has been found or not all processes have
121been signalled successfully.  Otherwise, a status of 0 will be
122returned.
123.Pp
124Diagnostic messages will only be printed if requested by
125.Fl d
126options.

130.Sh HISTORY
131The
132.Nm
133command appeared in

135It has been modeled after the
136.Nm
137command as available on other platforms.

140The
141.Nm
142program was originally written in Perl and was contributed by
143.An Wolfram Schneider ,
144this manual page has been written by
145.An J\(:org Wunsch .
146The current version of
147.Nm
148was rewritten in C by
149.An Peter Wemm
150using
151.Xr sysctl 3 .
