Which numeric value represents SIGHUP when using kill commands?

Explanation:
SIGHUP is the Hangup signal, and on Linux/Unix-like systems it is assigned the value 1. When you issue a kill command with that signal (for example, using the signal by name with -HUP or by number with -1), you are sending SIGHUP to the target process. The other common signals you might see—SIGINT is 2 (keyboard interrupt), SIGQUIT is 3, and SIGKILL is 9—represent different actions. So the numeric value that represents SIGHUP is 1.
