Change File Name From Upper To Lower Case

09.04.2005

        This script requires perl, and a modern shell with ls (this was written/tested using Bash).  It also will not work recursively without some modifications.

for file in `ls -1|perl -ne 'print "$_" if (/[A-Z]/);'`
do
  mv ${file} `echo ${file}|perl -ne 'chomp;print "$_" if (tr/A-Z/a-z/);'`;
done

Another one liner without using perl might be: for i in *; do mv $i `echo $i | tr [:upper:] [:lower:]`; done if you have lower case files this script will put a warning for them stating target file is same, but it's just a warning, that would change all files to lowercase.
