HOWTO: rename all files in lowercase

Pretty simple.

1. If you don’t have a *NIX operating system, please skip this post.

2. Create a script with the following content:

   #!/bin/sh  
   for f in *; do  
       g=`expr "xxx$f" : 'xxx(.*)' | tr '[A-Z]' '[a-z]'`  
       mv -n "$f" "$g"  
   done
   

   and call it rename.sh

3. Give it execution permissions, typing:

   $ chmod u+x rename.sh
   

4. Execute the script from the directory where you have your files to rename

If you have two files, Foo and foo, you’ll be notified and no files will be overwritten. So, don’t worry about that, you won’t lose any information. To be sure, try it with a few files in “/tmp” directory.
