Weird folder renamer (it's for a friend :) )

README.md

Put renamer.sh and renamer-aux.sh in a folder on your executable path (note that they should both be in the same folder).

Now cd somewhere and run renamer.sh, you'll get a series of mv commands to rename each folder from SOMEFOLDER/ to somefile-AT-somefolder/ where somefile is the name of the first file under somefolder/ (according to filename sort order).

Why would you need this? Beats me. A friend asked for it.

Note: Order does matter. The output you get from renamer.sh may contain (e.g.):

mv "/a/b/c/" "/a/b/something-AT-c"
mv /a/b/" "/a/aomething-AT-b"
mv "/a/" "/something-AT-a"

Doing them out of sequence would break - of course.

renamer-aux.sh

#!/bin/sh
cd "$1"
echo "mv \"$1/\" \"$1/../$(find . -type f -not -iname '.*' | sed -e 's/^.*\///' -e '/^\./d' |head -1 )-AT-$(basename "$1")\""

renamer.sh

#!/bin/sh
find -type d -not -iname '.*' -exec "$(dirname $0)/renamer-aux.sh" '{}' \;|LC_ALL=C sort -k5 -t\" -r
