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

139.Sh HISTORY
140The
141.Nm
142command appeared in

144It has been modeled after the
145.Nm
146command as available on other platforms.

149The
150.Nm
151program was originally written in Perl and was contributed by
152.An Wolfram Schneider ,
153this manual page has been written by
154.An J\(:org Wunsch .
155The current version of
156.Nm
157was rewritten in C by
158.An Peter Wemm
159using
