Actually i don't remember much about this, just found it while digging old files.

This program is intended to lower case the names of all files in the specified directory.

Originally i use codeblock, but since it really a simple (so simple, like a snippet it is) single source file project it should be easy to compile in gcc with this command.

   gcc main.c -o tolower

To lower case all file names in current directory:

    lowercase

or:

    lowercase .

To lower case all file names in spesific directory:

    lowercase <path of the directory>
