'echo' is your friend. Try: echo xargs -t -i mv {} `echo {} | sed 's/mode/dai/g'` to see that you were executing: xargs -t -i mv {} {} which is NOT what you wanted. You need to use proper quoting; and since you want to do programmatic shell actions on {}, you need your xargs to spawn an instance of sh. Try: xargs -t -i sh -c 'mv "$1" "$(echo "$1" | sed 's/mode/dai/g')"' sh {} -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
