The Killall command in the Linux system kills the process with the specified name (kill processes by name). We can use the KILL command to kill the process of the specified process PID, if we want to find the process we need to kill, we also need to use the PS and other commands to find the process with grep, and killall the two processes together, is a very useful command.

1. command format:

killall[parameter] [process name]

2. Command function:

Used to end all processes with the same name

3. Command parameters:

-Z only kills processes that have Scontext

-e requires matching process name

-I ignores lowercase

-G kills process groups rather than processes

-I interactive mode, before killing the process to ask the user first

-l list all known signal names

-Q does not output warning messages

-S sends the specified signal

-V report signal is sent successfully

-W waits for process to die

--HELP Display Help information

--version Display version display

4. Use instance:
