28.Os
29.Dt KILLALL 1
30.Sh NAME
31.Nm killall
32.Nd kill processes by name
33.Sh SYNOPSIS
34.Nm
35.Op Fl delmsvz
36.Op Fl help
37.Op Fl j Ar jid
38.Op Fl u Ar user
39.Op Fl t Ar tty
40.Op Fl c Ar procname
41.Op Fl SIGNAL
42.Op Ar procname ...
43.Sh DESCRIPTION
44The
45.Nm
46utility kills processes selected by name, as opposed to the selection by pid
47as done by
48.Xr kill 1 .
49By default, it will send a
50.Dv TERM
51signal to all processes with a real UID identical to the
52caller of
53.Nm
54that match the name
55.Ar procname .
56The super-user is allowed to kill any process.
57.Pp
58The options are as follows:
59.Bl -tag -width 10n -offset indent
60.It Fl d | v
61Be more verbose about what will be done.
62For a single
63.Fl d
64option, a list of the processes that will be sent the signal will be
65printed, or a message indicating that no matching processes have been
66found.
67.It Fl e
68Use the effective user ID instead of the (default) real user ID for matching
69processes specified with the
70.Fl u
71option.
72.It Fl help
73Give a help on the command usage and exit.
74.It Fl l
75List the names of the available signals and exit, like in
76.Xr kill 1 .
77.It Fl m
78Match the argument
79.Ar procname
80as a (case sensitive) regular expression against the names
81of processes found.
82CAUTION!
83This is dangerous, a single dot will match any process
84running under the real UID of the caller.
85.It Fl s
86Show only what would be done, but do not send any signal.
87.It Fl SIGNAL
88Send a different signal instead of the default
89.Dv TERM .
90The signal may be specified either as a name
91(with or without a leading
92.Dv SIG ) ,
93or numerically.
94.It Fl j Ar jid
95Kill processes in the jail specified by
96.Ar jid .
97.It Fl u Ar user
98Limit potentially matching processes to those belonging to
99the specified
100.Ar user .
101.It Fl t Ar tty
102Limit potentially matching processes to those running on
103the specified
104.Ar tty .
105.It Fl c Ar procname
106When used with the
107.Fl u
108or
109.Fl t
110flags, limit potentially matching processes to those matching
111the specified
112.Ar procname .
113.It Fl z
114Do not skip zombies.
115This should not have any effect except to print a few error messages
116if there are zombie processes that match the specified pattern.
117.El
118.Sh ALL PROCESSES
119Sending a signal to all processes with uid
120.Em XYZ
121is already supported by
122.Xr kill 1 .
123So use
124.Xr kill 1
125for this job (e.g.\& $ kill -TERM -1 or
126as root $ echo kill -TERM -1 | su -m <user>)
127.Sh EXIT STATUS
128The
129.Nm
130command will respond with a short usage message and exit with a status
131of 2 in case of a command error.
132A status of 1 will be returned if
133either no matching process has been found or not all processes have
134been signalled successfully.
135Otherwise, a status of 0 will be
136returned.
137.Sh DIAGNOSTICS
138Diagnostic messages will only be printed if requested by
139.Fl d
140options.

146.Sh HISTORY
147The

153command as available on other platforms.
