 There are no prerequisites or dependencies beyond Perl itself: just download it, make sure it's executable, and run it.  On Linux or BSD or Mac, you should already have Perl, and I'd recommend putting it in `/usr/local/bin` and `chmod 755 /usr/local/bin/blindrename.pl`, after which you can just type **blindrename.pl** ***foldername*** and it will obligingly do its thing.  On Windows... well, do whatever you need to do to run a Perl script on Windows.  (If you're a lost little scientist with only Windows: check out <a href="http://www.cygwin.com/" target="_blank">Cygwin</a> or <a href="http://www.activestate.com/activeperl" target="_blank">ActivePerl</a> for Windows implementations of Perl.)
 
-`blindrename.pl` is reasonably smart - it will test to make sure that you supply a foldername, and that the foldername exists and is a folder.  It also refuses to blindrename a folder *twice* - if there's already a `keyfile.csv` present, it'll die and let you know why.  It logs each rename to `keyfile.csv` *before* actually performing the operation, and will die if it can't successfully rename a file.  Finally, it won't traverse subdirectories, and it won't rename dotfiles.  With all that said... this is still a potentially **really destructive** operation.  **Don't** run `blindrename.pl` on any important system folders, please... including but not limited to your own home folder!
