Subject: Tip of the day: prune empty directory hierarchies
Date: Mon, 29 Jun 2015 15:59:27 +0100 [thread overview]
Message-ID: <20150629155927.289729cb@pwslap01u.europe.root.pri> (raw)
In case anybody ever wanted this and there isn't a standard solution I
don't know about...
pws
# Prune empty directory hierarchies below the current directory. That's
# a hierarchy where everything underneath is itself a directory.
#
# The first search is slow, but subsequently it simply goes up one
# directory each time so it's much faster.
local -aU dirs
dirs=(**/*(ND/^F))
while (( ${#dirs} )); do
rmdir $dirs || return
# print Pruhed ${#dirs} directories...
dirs=(${^dirs:h}(ND/^F))
done
