Subject: warning about closing an already closed file descriptor
Date: Mon, 19 Jan 2015 14:33:25 +0100 [thread overview]
Message-ID: <1469711.vAe1BPIYVt@kdudka.brq.redhat.com> (raw)
zsh prints a warning if an already closed file descriptor is to be closed.
While this is technically correct, the other shells I tried (ksh and bash)
do not print any such warning:
$ bash -c '(true <&-) <&-'
$ ksh -c '(true <&-) <&-'
$ zsh -c '(true <&-) <&-'
zsh:1: failed to close file descriptor 0: bad file descriptor
The warning was introduced by the following commit:
http://sourceforge.net/p/zsh/code/ci/45913f43
... and it causes problems when porting legacy scripts to a newer version
of zsh. Is there any way to suppress the warning?
If not, how can one achieve compatibility with other shells (including
older versions of zsh)?
Kamil
