Converting filenames to lowercase
27 July 2004 @ 13:19 BST

The easiest way to convert all the files to lowercase is to use rename. Like this:

rename 'y/A-Z/a-z/' *

Here is a shell script to convert all files in the working directory to lowercase:

#!/bin/bash
for filename in *
do
   n=`echo $filename | tr '[:upper:]' '[:lower:]'`
   mv $filename $n
done

Here is a perl one-line that does the same thing from the command line:

perl -MFile::Copy -e 'move $_, lc($_) foreach glob "*"'

And a perl script that does the same thing:

#!/usr/bin/perl

use warnings;
use strict;
use File::Copy;

move $_, lc($_) foreach glob '*';



The last perl script is dangerous, as it overwrites files when they acquire the same name due to the conversion.

convmv can do that job, too - even if files contain umlauts in arbitrary charsets.
