How to kill processes in Linux

[@shaheryarmuhammadali5843]

Nowadays internet browsers (chrome/firefox) spawn multiple processes after being started. Does using kill or xkill terminate the child processes as well or only the parent process? In Windows Task Manager and other equivalent Process Managers like Process Explorer and System Informer, we have the option to 'Terminate Tree' which will do the same.

xkill will kill the main process and child processes for the window you click on. I forgot to mention killall which you use by typing killall and then the program name. Ex. killall chrome which will kill all processes for chrome.
