Subject: uncommon shell code
Date: Thu, 22 Sep 2005 15:32:43 +0100	[thread overview]
Message-ID: <72499e3b05092207326abadd91@mail.gmail.com> (raw)

Hi,

I found the following shell code in git-tag.sh (and others):

while case "$#" in 0) break ;; esac
do
  ...
done

Why not use the straight forward code:

while test "$#" -ne 0
do
   ...
done

Are there any functional difference between them?
