Different signal commands in the System Monitor

[rgbellotti]

In the system monitor process table, it gives you the option to right-click on any running process, which brings up a menu with the option "Send Signal". Can you please explain the differences in functionality between the signal options Hangup (HUP), Interrupt (INT), Terminate (TERM), and Kill (KILL)?

Sure thing dude! Here's a quick rundown of the signal options you mentioned:

- Hangup (HUP) - this signal is typically used to tell a program to reload its configuration files. When a hangup signal is sent to a running process, it usually terminates the process and all its child processes and then restarts it.

- Interrupt (INT) - this signal is used to interrupt a running process. When you send an interrupt signal to a process, it usually terminates the process gracefully and frees any resources it had allocated.

- Terminate (TERM) - this signal tells a program to terminate gracefully. When a terminate signal is sent to a process, it usually shuts down and frees any resources it had allocated.

- Kill (KILL) - this is a more forceful way to terminate a process. When you send a kill signal to a process, it terminates the process immediately without allowing it to perform any cleanup activities or free resources.

Hope that helps you out, let me know if you have any more questions!
