27 !!DESCRIPTION
28
29
30 __killall__ sends a signal to all processes running any
31 of the specified commands. If no signal name is specified,
32 SIGTERM is sent.
33
34
35 Signals can be specified either by name (e.g. __-HUP__)
36 or by number (e.g. __-1__).
37
38
39 If the command name contains a slash (__/__), processes
40 executing that particular file will be selected for killing,
41 independent of their name.
42
43
44 __killall__ returns a non-zero return code if no process
45 has been killed for any of the listed commands. If at least
46 one process has been killed for each command, __killall__
47 returns zero.
48
49
50 A __killall__ process never kills itself (but may kill
51 other __killall__ processes).
52 !!OPTIONS

54
55 __-e__, __--exact__
56
57
58 Require an exact match for very long names. If a command
59 name is longer than 15 characters, the full name may be
60 unavailable (i.e. it is swapped out). In this case,
61 __killall__ will kill everything that matches within the
62 first 15 characters. With __-e__, such entries are
63 skipped. __killall__ prints a message for each skipped
64 entry if __-v__ is specified in addition to
65 __-e__,
66
67
68 __-g__, __--process-group__
69
70
71 Kill the process group to which the process belongs. The
72 kill signal is only sent once per group, even if multiple
73 processes belonging to the same process group were
74 found.
75
76
77 __-i__, __--interactive__
78
79
80 Interactively ask for confirmation before
81 killing.
82
83
84 __-l__, __--list__
85
86
87 List all known signal names.
88
89
90 __-q__, __--quiet__
91
92
93 Do not complain if no processes were killed.
94
95
96 __-v__, __--verbose__
97
98
99 Report if the signal was successfully sent.
100
101
102 __-V__, __--version__
103
104
105 Display version information.
106
107
108 __-w__, __--wait__
109
110
111 Wait for all killed processes to die. __killall__ checks
112 once per second if any of the killed processes still exist
113 and only returns if none are left. Note that __killall__
114 may wait forever if the signal was ignored, had no effect,
115 or if the process stays in zombie state.

120 !!KNOWN BUGS
121
122
123 Killing by file only works for executables that are kept
124 open during execution, i.e. impure executables can't be
125 killed this way.
126
127
128 Be warned that typing __killall__ ''name'' may not
129 have the desired effect on non-Linux systems, especially
130 when done by a privileged user.
131
132
133 __killall -w__ doesn't detect if a process disappears and
134 is replaced by a new process with the same PID between
135 scans.
