SIGHUP (1)The controlling terminal was closed or the session leader process ended.

Use nohup or screen/tmux to keep processes running after logout. For daemons, implement a SIGHUP handler to reload configuration.
# Send SIGHUP to reload config
kill -HUP $(pidof nginx)
# Trap SIGHUP in bash
trap 'echo reloading' HUPENOMEDIUMNo removable medium is present in the drive or device.
