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 delmsvz
36.Op Fl help
37.Op Fl I
38.Op Fl j Ar jail
39.Op Fl u Ar user
40.Op Fl t Ar tty
41.Op Fl c Ar procname
42.Op Fl Ar SIGNAL
43.Op Ar procname ...
44.Sh DESCRIPTION
45The
46.Nm
47utility kills processes selected by name, as opposed to the selection by PID
48as done by
49.Xr kill 1 .
50By default, it will send a
51.Dv TERM
52signal to all processes with a real UID identical to the
53caller of
54.Nm
55that match the name
56.Ar procname .
57The super-user is allowed to kill any process.
58.Pp
59The options are as follows:
60.Bl -tag -width ".Fl c Ar procname"
61.It Fl d | v
62Be more verbose about what will be done.
63For 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 e
69Use the effective user ID instead of the (default) real user ID for matching
70processes specified with the
71.Fl u
72option.
73.It Fl help
74Give a help on the command usage and exit.
75.It Fl I
76Request confirmation before attempting to signal each
77process.
78.It Fl l
79List the names of the available signals and exit, like in
80.Xr kill 1 .
81.It Fl m
82Match the argument
83.Ar procname
84as a (case sensitive) regular expression against the names
85of processes found.
86CAUTION!
87This is dangerous, a single dot will match any process
88running under the real UID of the caller.
89.It Fl s
90Show only what would be done, but do not send any signal.
91.It Fl Ar SIGNAL
92Send a different signal instead of the default
93.Dv TERM .
94The signal may be specified either as a name
95(with or without a leading
96.Dq Li SIG ) ,
97or numerically.
98.It Fl j Ar jail
99Kill processes in the specified
100.Ar jail .
101.It Fl u Ar user
102Limit potentially matching processes to those belonging to
103the specified
104.Ar user .
105.It Fl t Ar tty
106Limit potentially matching processes to those running on
107the specified
108.Ar tty .
109.It Fl c Ar procname
110Limit potentially matching processes to those matching
111the specified
112.Ar procname .
113.It Fl q
114Suppress error message if no processes are matched.
115.It Fl z
116Do not skip zombies.
117This should not have any effect except to print a few error messages
118if there are zombie processes that match the specified pattern.
119.El
120.Sh ALL PROCESSES
121Sending a signal to all processes with the given UID
122is already supported by
123.Xr kill 1 .
124So use
125.Xr kill 1
126for this job (e.g.\&
127.Dq Li "kill -TERM -1"
128or as root
129.Dq Li "echo kill -TERM -1 | su -m <user>" ) .
130.Sh IMPLEMENTATION NOTES
131This
132.Fx
133implementation of
134.Nm
135has completely different semantics as compared to the traditional
136.Ux
137System V behavior of
138.Nm .
139The latter will kill all processes that the current user is able to
140kill, and is intended to be used by the system shutdown process only.
141.Sh EXIT STATUS
142The
143.Nm
144utility exits 0 if some processes have been found and
145signalled successfully.
146Otherwise, a status of 1 will be
147returned.
148.Sh DIAGNOSTICS
149Diagnostic messages will only be printed if requested by
150.Fl d
151options.
152.Sh SEE ALSO

154.Xr pkill 1 ,

157.Sh HISTORY
158The
159.Nm
160command appeared in
161.Fx 2.1 .
162It has been modeled after the
163.Nm
164command as available on other platforms.
165.Sh AUTHORS
166.An -nosplit
167The
168.Nm
169program was originally written in Perl and was contributed by
170.An Wolfram Schneider ,
171this manual page has been written by
172.An J\(:org Wunsch .
173The current version of
174.Nm
175was rewritten in C by
176.An Peter Wemm
177using
178.Xr sysctl 3 .
