Syntax

killall [<PARAMETER> ...] <NAME> [...]
killall -l

Parameters

-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).

-l, --list

List all known signal names.

-q, --quiet

Do not complain if no processes were killed.

-r, --regexp

Interpret process name pattern as an extended regular expression.

-s <SIGNAL>, --signal <SIGNAL>

Send this signal instead of SIGTERM.

-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:

killall may wait forever if the signal was ignored, had no effect, or if the process stays in zombie state.
