Package: zsh
Version: 4.3.9-1
Severity: normal
The command
zsh -c 'set -e; ! true; echo OK'
fails to output OK, thus does not conform to POSIX:
-e When this option is on, if a simple command fails for any of the
reasons listed in Section 2.8.1 (on page 2315) or returns an exit
status value >0, and is not part of the compound list following a
while, until, or if keyword, and is not a part of an AND or OR
list, and is not a pipeline preceded by the ! reserved word, then
the shell shall immediately exit.
bash, dash and ksh93 are correct (but not pdksh, posh and zsh).
There's currently a discussion about "set -e" in the austin group
mailing-list, but there does not seem to be any ambiguity on the
above point, as only "! true" returns an exit status value >0 but
this is not a simple command. And concerning historical behavior,
both ksh93 and bash output OK. So, I think that pdksh, posh and
zsh should follow.
Also the bug seems to be already accepted for pdksh:
