28.Os FreeBSD 2.2
29.Dt KILLALL 1
30.Sh NAME
31.Nm killall
32.Nd kill processes by name
33.Sh SYNOPSIS
34.Nm killall
35.Op Fl d \&| Ns Fl v
36.Op Fl h \&| Ns Fl \&?
37.Op Fl help
38.Op Fl l
39.Op Fl m
40.Op Fl s
41.Op Fl SIGNAL
42.Ar procname ...
43.Sh DESCRIPTION
44.Nm Killall
45kills processes selected by name, as opposed to the selection by pid
46as done by
47.Xr kill 1 .
48By default, it will send a
49.Dv TERM
50signal to all processes with an effective UID identical to the
51caller of
52.Nm
53that match the name
54.Ar procname .
55The super-user is allowed to kill any process.
56.Pp
57The options are as follows:
58.Bl -tag -width 10n -offset indent
59.It Fl d \&| Ns Fl v
60Be more verbose about what will be done.  For a single
61.Fl d
62option, a list of the processes that will be sent the signal will be
63printed, or a message indicating that no matching processes have been
64found.  If the option
65.Fl d
66has been specified at least twice, the effective UID, PID, and name
67of all processes found in
68.Xr procfs 5
69will be listed in addition.
70.It Fl h \&| Ns Fl \&?
71.It Fl help
72Give a help on the command usage and exit.
73.It Fl l
74List the names of the available signals and exit, like in
75.Xr kill 1 .
76.It Fl m
77Match the argument
78.Ar procname
79as a (case insensitive) regular expression against the names
80of processes found in
81.Xr procfs 5 .
82CAUTION!  This is dangerous, a single dot will match any process
83running under the effective UID of the caller.  The regular expression
84syntax in effect is that used by
85.Xr perl 1 .
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.Pq with \&or without a leading Dv SIG ,
93or numerically.
94.El
95
96.Sh ALL PROCESSES
97Sending a signal to all processes with uid
98.Nm XYZ
99is already supported by
100.Xr kill 1 .
101So use
102.Xr kill 1
103for this job (e.g. $ kill -TERM -1 or
104as root $ echo kill -TERM -1 | su -m <user>)
105
106
107.Sh DIAGNOSTICS
108The
109.Nm
110command will respond with a short usage message and exit with a status
111of 2 in case of a command error.  A status of 1 will be returned if
112either no matching process has been found or not all processes have
113been signalled successfully.  Otherwise, a status of 0 will be
114returned.
115.Pp
116Diagnostic messages will only be printed if requested by
117.Fl d
118options.

122.Sh HISTORY
123The
124.Nm
125command appeared in
126.Fx 2.1 .
127It has been modeled after the
128.Nm
129command as available on other platforms.
