fetchmail[edit]

Isn't nohup in that fetchmail example superfluous since -d actually makes it a real daemon? 70.82.141.92

Yes, because fetchmail registers its own signal handler for SIGHUP – this is mentioned in the man page. nohup is only useful when the default signal handler would otherwise be used, terminating the process. — Lee J Haywood 21:15, 10 November 2005 (UTC)[reply]

Well, not only that; the main difference is that fetchmail -d already is a DAEMON, so it won't get any SIGHUP automatically because it'll detach from the controlling terminal and run in its own session (calls setsid(2)). This is different from how nohup(1) works. 70.82.141.92 02:35, 14 November 2005 (UTC)[reply]

weirdness[edit]

ANd here's some extra nohup weirdness. 70.82.141.92

Still didnt answer the question[edit]

As a user coming in here looking for info on nohup , The article fails to explain what happens when the user logs in again example

nohup wget a 1000 gb file &

When i log in is wget still spewing out information onto the telnet screen or does this program merely let the program run in the background and not be accesed again. —Preceding unsigned comment added by 86.46.165.229 (talk) 01:38, 11 June 2009 (UTC)[reply]

this article does not really answer your "log off / log in again" question because nohup knows nothing about logging in / logging off, this is way beyond of its very limited concern. Still, if you carefully read the article again, the explanations about redirections can give you a clue. But the best for you is to check the documentation of GNU Screen; a real, full-featured application as opposed to the minor nohup command Marchash (talk) 08:21, 11 June 2009 (UTC)[reply]

manpage link[edit]

The manpage link seems to be broken 190.138.237.70 (talk) 19:50, 4 January 2008 (UTC)[reply]

I replaced it with one that works. --Unixguy (talk) 19:01, 7 January 2008 (UTC)[reply]

Wikipedia NOT INFO[edit]

Thumperward, if you really think this page deserves this:

then I am afraid you are basically going to have to tag most computer-related pages the same. Marchash (talk) 08:22, 11 June 2009 (UTC)[reply]

Double redirects[edit]

I had a program that I wanted to run with STDOUT to a file. Then I wanted to nohup it as well, keeping the program output separate. I sort of started off with:

nohup program >> program.out > /dev/null 2>&1

but this didnt work, so I settled for:

nohup `program >> program.out` > /dev/null 2>&1

which did work but was a bit of a mess, frankly. Anyone want to add these sort of conundrums to the article? — Preceding unsigned comment added by 82.134.237.45 (talk) 09:33, 18 March 2013 (UTC)[reply]

Relationship to systemd[edit]

Seems like there's some interesting things with systemd these days, after reading through Kill user session scope by default #3005 over on Github. Article might be able to benefit from some exploration of that - or maybe another article... Ben Creasy (talk) 08:09, 24 November 2016 (UTC)[reply]
