How to convert the value of %USERNAME% to lowercase within a Windows batch script?

Question

I\'m automating some source control software functionality using a dot bat script but given that our svn repos are hosted in a *NIX box, I\'m facing the eternal case problem

Answer 1

In my batch file I'm doing a comparsion between %USERNAME% and a CSV file.

The program would not work if user was logged in UperCase username.

Ex:
Login : GB2NOGU // Won't work
Login : gb2nogu // Works

Here I could solve my problem doing a insensitive comparison.

if /i %USERNAME%==gb2nogu (
     // Code here
)

The parameter /i tells the cmd to do a insensitive case comparison, so it'll ignore the difference between lowercase and uppercase letters.
