Doc Text:
The tcsh(1) man page inaccurately stated that the "hup" and "nohup" built-in commands, when used without an argument, can be used only within a shell script. The man page has been corrected: it now states that the hup and nohup built-in commands can be used when running the shell non-interactively.

This is a patch fixing the bug.

Comment 2 Cai Xianchao 2008-03-12 07:07:08 UTC
I made a mistake.

"Actual results:" should be "Nothing is outputed.".
"Expected results:" should be "An error message is outputed.".


Comment 3 RHEL Program Management 2011-01-11 19:57:57 UTC
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.

Comment 4 RHEL Program Management 2011-01-12 15:14:33 UTC
This request was erroneously denied for the current release of
Red Hat Enterprise Linux.  The error has been fixed and this
request has been re-proposed for the current release.
