Again, some googling found me some Unix find command examples from which I was able to adpat an example to write this code find . -type f -name "*" -exec mv {} {}.txt \; which renames every file under the current directory to .txt.... http://www.stuartwoodward.com/tech/archives/000382.html Just for laughs, I decided to install Debian Linux on my old Sony notebook.
