Linux killall command

Linux 命令大全Linux Command Encyclopedia

Linux killall is used to kill a process. Unlike kill, it kills all processes with the specified name.

The kill command kills a process with a specified PID and needs to be used together with ps, while killall directly operates on the process name, which is more convenient.

Syntax

  killall [选项]  name

Parameter description：

  • name: process name

The options include the following parameters:
  • -e | --exact: the process must match the name exactly
  • -I | --ignore-case: ignore case
  • -g | --process-group: terminate the process group
  • -i | --interactive: ask before terminating
  • -l | --list: list all signal names
  • -q | --quite: when the process does not end, no information is output
