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 jail
38.Op Fl u Ar user
39.Op Fl t Ar tty
40.Op Fl c Ar procname
41.Op Fl Ar 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 ".Fl c Ar procname"
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 Ar 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.Dq Li SIG ) ,
93or numerically.
94.It Fl j Ar jail
95Kill processes in the specified
96.Ar jail .
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
106Limit potentially matching processes to those matching
107the specified
108.Ar procname .
109.It Fl z
110Do not skip zombies.
111This should not have any effect except to print a few error messages
112if there are zombie processes that match the specified pattern.
113.El
114.Sh ALL PROCESSES
115Sending a signal to all processes with the given UID
116is already supported by
117.Xr kill 1 .
118So use
119.Xr kill 1
120for this job (e.g.\&
121.Dq Li "kill -TERM -1
122or as root
123.Dq Li "echo kill -TERM -1 | su -m <user>" ) .
124.Sh EXIT STATUS
125The
126.Nm
127utility exits 0 if some processes have been found and
128signalled successfully.
129Otherwise, a status of 1 will be
130returned.
131.Sh DIAGNOSTICS
132Diagnostic messages will only be printed if requested by
133.Fl d
134options.
135.Sh SEE ALSO
136.Xr kill 1 ,
137.Xr pkill 1 ,

140.Sh HISTORY
141The
142.Nm
143command appeared in
144.Fx 2.1 .
145It has been modeled after the
146.Nm
147command as available on other platforms.

150The
151.Nm
152program was originally written in Perl and was contributed by
153.An Wolfram Schneider ,
154this manual page has been written by
155.An J\(:org Wunsch .
156The current version of
157.Nm
158was rewritten in C by
