[SOLVED] HUP signal

Post by JadedMonk »

While doing some reading, I came across the term, "HUP Signal". Searches on various search engines revealed very little. Could someone please tell me what an "HUP Signal" is?

I assume it has to do with running commands in the background... thank you in advance.

HUP is an abbreviation for "hang up". It dates back from the days of dial-up modems - It was originally designed to notify the process of a serial line drop. Think of it kind of as a "kill & then restart" command. Close the controlling pseudo or virtual terminal process, then (in many cases) try to continue/restart it. The intention is to prevent a hanging process from crashing & bringing down the rest of the system.
