28.Dt KILLALL 1
29.Os
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 q
37.Op Fl h | ?\&
38.Op Fl help
39.Op Fl l
40.Op Fl m
41.Op Fl s
42.Op Fl T
43.Op Fl u Ar user
44.Op Fl t Ar tty
45.Op Fl c Ar procname
46.Op Fl j Ar jail
47.Op Fl SIGNAL
48.Op Ar procname ...
49.Sh DESCRIPTION
50The
51.Nm
52utility kills processes selected by name, as opposed to the selection by pid
53as done by
54.Xr kill 1 .
55By default, it will send a
56.Dv TERM
57signal to all processes with a real UID identical to the
58caller of
59.Nm
60that match the name
61.Ar procname .
62The super-user is allowed to kill any process.
63.Pp
64The options are as follows:
65.Bl -tag -width 10n -offset indent
66.It Fl q
67Do not print an error message if no matching processes are found.
68.It Fl d | v
69Be more verbose about what will be done.  For a single
70.Fl d
71option, a list of the processes that will be sent the signal will be
72printed, or a message indicating that no matching processes have been
73found.
74.It Fl h | ?\&
75.It Fl help
76Give a help on the command usage and exit.
77.It Fl l
78List the names of the available signals and exit, like in
79.Xr kill 1 .
80.It Fl m
81Match the argument
82.Ar procname
83as a (case insensitive) regular expression against the names
84of processes found.
85CAUTION!  This is dangerous, a single dot will match any process
86running under the real UID of the caller.
87.It Fl s
88Show only what would be done, but do not send any signal.
89.It Fl SIGNAL
90Send a different signal instead of the default
91.Dv TERM .
92The signal may be specified either as a name
93(with or without a leading
94.Dv SIG ) ,
95or numerically.
96.It Fl u Ar user
97Limit potentially matching processes to those belonging to
98the specified
99.Ar user .
100.It Fl t Ar tty
101Limit potentially matching processes to those running on
102the specified
103.Ar tty .
104.It Fl T
105Kill all processes on the current tty except ourselves or
106processes which parent us.
107.It Fl j Ar jailid
108Limit potentially matching processes to those running in the jail with id
109.Ar jailid .
110.It Fl c Ar procname
111When used with the
112.Fl u
113or
114.Fl t
115flags, limit potentially matching processes to those matching
116the specified
117.Ar procname .
118.El
119.Sh ALL PROCESSES
120Sending a signal to all processes with uid
121.Em XYZ
122is already supported by
123.Xr kill 1 .
124So use
125.Xr kill 1
126for this job (e.g. $ kill -TERM -1 or
127as root $ echo kill -TERM -1 | su -m <user>)
128.Sh DIAGNOSTICS
129The
130.Nm
131command will respond with a short usage message and exit with a status
132of 2 in case of a command error.  A status of 1 will be returned if
133either no matching process has been found or not all processes have
134been signalled successfully.  Otherwise, a status of 0 will be
135returned.
136.Pp
137Diagnostic messages will only be printed if requested by
138.Fl d
139options.

143.Sh HISTORY
144The

148It has been modeled after the
149.Nm
150command as available on other platforms.

154.Nm
155program was originally written in Perl and was contributed by

159The current version of
160.Nm
