killall sends a signal to all processes running any of the specified commands. If no signal name is specified, SIGTERM is sent.
Signals can be specified either by name (e.g., -HUP or -SIGHUP) or by number (e.g., -1) or by option -s.
If the command name is not a regular expression (option -r) and contains a slash (/), processes executing that particular file will be selected for killing, independent of their name.
killall returns a zero return code if at least one process has been killed for each listed command, or no commands were listed and at least one process matched the -u and -Z search criteria. killall returns non-zero otherwise.
A killall process never kills itself (but may kill other killall processes).
Require an exact match for very long names. If a command name is longer than 15 characters, the full name may be unavailable (i.e. it is swapped out). In this case, killall will kill everything that matches within the first 15 characters. With -e, such entries are skipped. killallprints a message for each skipped entry if -v is specified in addition to -e.
-I, --ignore-case
Do case insensitive process name match.
-g, --process-group
Kill the process group to which the process belongs. The kill signal is only sent once per group, even if multiple processes belonging to the same process group were found.
-i, --interactive
Interactively ask for confirmation before killing.
-l, --list
List all known signal names.
-o, --older-than
Match only processes that are older (started before) the time specified. The time is specified as a float then a unit. The units are s,m,h,d,w,M,yfor seconds, minutes, hours, days, weeks, Months, and years respectively.
-q, --quiet
Do not complain if no processes were killed.
-r, --regexp
Interpret process name pattern as an extended regular expression.
-s, --signal
Send this signal instead of SIGTERM.
-u, --user
Kill only processes the specified user owns. Command names are optional.
-v, --verbose
Report if the signal was successfully sent.
-V, --version
Display version information.
-w, --wait
Wait for all killed processes to die. killall checks once per second if any of the killed processes still exist and only returns if none are left. Note that killall may wait forever if the signal was ignored, had no effect, or if the process stays in zombie state.
-y, --younger-than
Match only processes that are younger (started after) the time specified. The time is specified as a float then a unit. The units are s,m,h,d,w,M,yfor seconds, minutes, hours, days, weeks, Months, and years respectively.
-Z, --context
(SELinux Only) Specify security context: kill only processes having security context that match with given expended regular expression pattern. Must precede other arguments on the command line. Command names are optional.
Killing by file only works for executables that are kept open during execution, i.e. impure executables can't be killed this way.
Be warned that typing killall name may not have the desired effect on non-Linux systems, especially when done by a privileged user.
killall -w doesn't detect if a process disappears and is replaced by a new process with the same PID between scans.
If processes change their name, killall may not be able to match them correctly.
killall has a limit of names that can be specified on the command line. This figure is the size of an unsigned long multiplied by 8. For most 32 bit systems the limit is 32 and similarly for a 64 bit system the limit is usually 64.

killall 已知錯誤
請注意，鍵入KILLALL名稱可能不會在非Linux系統上產生預期的效果，特別是在特權用戶執行時。
KILLALL-w不檢測進程是否消失，并由掃描之間具有相同PID的新進程替換。
如果進程更改其名稱，則KILLALL可能無法正確匹配它們。
KILLALL有一個可以在命令行上指定的名稱的限制。這個數字是無符號長乘以8的大小。對于大多數32位系統，極限是32，對于64位系統，限制通常是64。
