[ale] 2 Perl questions ?

Hi,

I would recommend writing a shell script for this.
To do this you would need to use the find program, which is the most 
commonly used file system traversal utility used with shell scripts.

If you need to take some action based on a file that matches a certain 
criteri, use the -exec switch.

Some examples :

Here is a script to recursively rename file extensions using find.

Thanks,
