Almost always, command line tools are more efficient than desktop ones, especially for file management. Recently, however, I found myself needing to clean up the file names from six hundred ripped CDs, removing illegal characters, replacing spaces with hyphens, and half a dozen other minor adjustments. To my surprise, the most convenient tools for the task were on the desktop: The Thunar Bulk Rename utility, KRename, GPRename, and pyRenamer.
The trouble was, I needed more options that the mv command supports. Working on a Debian system, I could have used the rename command, if I remembered enough Perl to make it effective. And, of course, I could have written a BASH script or played around with sed. But all these would have taken time when I wanted instant gratification, so I turned to these desktop tools hoping for a quick fix.
