|Linux / Unix Command: killall|
NAMEkillall - kill processes by name
SYNOPSISkillall [-e,--exact] [-g,--process-group] [-i,--interactive] [-q,--quiet] [-v,--verbose] [-w,--wait] [-V,--version] [-S,--sid] [-c,--context] [-s,--signal signal] [--] name ...
DESCRIPTIONkillall 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 by number (e.g. -1).
If the command name 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 ilisted command. killall returns zero otherwise.
- -e, --exact
- 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. killall prints a message for each skipped entry if -v is specified in addition to -e,
- -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.
- -q, --quiet
- Do not complain if no processes were killed.
- -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.
- (Flask only) Specify SID: kill only processes with given SID. Mutually exclusive with -c argument. Must precede other arguments on command line.
- (Flask only) Specify security context: kill only processes with given security context. Mutually exclusive with -s. Must precede other arguments on the command line.
