killall linux command

killall

killall [options] names

Kill processes by command name. If more than one process is running the specified command, kill all of them. Treat command names that contain a / as files; kill all processes that are executing that file.

Options

-signal

Send signal to process (default is TERM). signal may be a name or number.

-e

Require an exact match to kill very long names (i.e., longer than 15 characters). Normally, killall kills everything that matches within the first 15 characters. With -e, such entries are skipped. (Use -v to print a message for each skipped entry.)

-g

Kill the process group to which the process belongs.

-i

Prompt for confirmation before killing processes.

-l

List known signal names.

-q

Quiet; do not complain of processes not killed.

-v

Verbose: after killing process, report success and process ID.

-V

Print version information.

-w

Wait for all killed processes to die. Note that killall may wait forever if the signal was ignored or had no effect, or if the process stays in zombie state.
