Developer tools - renaming files

It sometimes happens that we need to rename files to fix a file naming convention. This happened to me as well. Last time when I followed the suggestion to mix all words in the file name without any delimiter.

This is a very fragile suggestion but I usually used to name files like: FirstSecond or first-second as that makes it visually more readable but what if in the bigger project I want to look for the file. If I search visually without any engine for the file that's better for reading but when we want manually navigate for the let's say for the key: headerbar. It's not so obvious to type headerbar header-bar or HeaderBar.

Here I want to share my perl script for renaming: rename-files.pl
