You No. It seems if I didn't set huponexit, logout won't send either "HUP" or "TERM" to the background process. The process will keep running, like a daemon after the logout. But if I set the huponexit, logout will kill the background process with some other signals, they are not HUP or TERM. If I sent HUP to the session leader of the control terminal (the bash I think, and it didn't set huponexit), the bash will quit. Before that, the bash will first send HUP to the background process and then send another signal other than TERM to kill it. I think the "HUP" means the terminal maybe broken, so bash will signal each of its child to quit. But only logout it won't signal children. > need to trap that signal as well or use a "disown" on the PID of the > child process to disassociate it from the login shell. Thank you for pointing out the "disown". -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
