Terminate a program using the SIGHUP (hang up) signal. Many daemons will reload instead of terminating

Example: kill {{[-1|-HUP]}} {{process_id}}

Terminate a program using the SIGINT (interrupt) signal. This is typically initiated by the user pressing `<Ctrl c>`

Example: kill {{[-2|-INT]}} {{process_id}}

-9boolean

Signal the operating system to immediately terminate a program (which gets no chance to capture the signal)

Example: kill {{[-9|-KILL]}} {{process_id}}

Signal the operating system to pause a program until a SIGCONT ("continue") signal is received

Example: kill {{[-19|-STOP]}} {{process_id}}
