Disown ignore hup signal, make background run

nohup,setsid,& can prevent the program from being affected by HUP signals

If a command is not submitted with the above command, then we can use the disown command to make it unaffected by the HUP signal:

When a program is not affected by a suspend:

CTRL + Z causes the current process to suspend to run in the background

(FG puts the pending process back into the foreground)

BG runs a suspended process in the background

Disown-h%1 first job ignores HUP signal

Disown-ah All jobs ignore HUP signal

Disown-rh running function ignores HUP signal
