Additional Notes
killall is a process-management command used to send a signal to processes by name. It terminates all processes matching a given name, rather than targeting individual PIDs.
On Linux, killall matches process names exactly by default. On some other systems (like Solaris), killall kills all processes, so check behavior before relying on it cross-platform.

Process-name matching can affect more than one process. Use pgrep -a NAME first when unsure.
