Using sed to rename files in more or less one line ;)

SED-renamer

# for example ".bak"
TOKEN=.bak
ETOKEN=`echo $TOKEN |sed 's/\./\\\./'`

# any suggestions how to get rid of this "bash" at the end are appreciated
# also: alternatively there is a NOT opperator on sed's regex - not used here

find . -path "*$TOKEN" -d 1 |sed 's/^\.\(.*\)\($ETOKEN\)$/mv `pwd`\1\2 `pwd`\1/'|bash
