Subject: 'case' zeroes "$?"
Date: Sun, 9 Oct 2016 23:01:35 +0200	[thread overview]
Message-ID: <3493e3d3-e578-31d1-27de-06d8d0c35944@inlv.org> (raw)

Unlike on other shells, 'case' on zsh zeroes "$?" before executing a
command within 'case', making it more inconvenient to test exit status.

Example:

(exit 37) || case $? in 37) echo "$?";; esac

All shells except zsh and Busybox ash output 37; zsh outputs 0.
(dash recently fixed this: 0.5.8 outputs 0, 0.5.9.1 outputs 37.)

Thanks,

- Martijn
