Subject: Maildir empty?
Date: Mon, 12 Jul 2004 09:37:05 +0200 [thread overview]
Message-ID: <20040712073705.GN2860@born.physik.uni-dortmund.de> (raw)
Dear zsh, is there a zsh-internal way to find out whether a maildir is
empty? Or more generally, whether a directory tree contains no
files? The following test ($i is the pathname of the maildir):
if [[ $(echo $i/*/* | wc -w) -eq 0 ]]
works with `setopt extendedglob nullglob', but I am sure there is some
combination of {}[]()$#@% which avoids spawning of a subshell and an
external program.
