Do you work at a Linux | UNIX shell, and also at a DOS prompt?

Are you always typing in "ls" only to get:
'ls' is not recognized as an internal or external command, operable program or batch file.

Well, now you can!
Requirements: some kind of DOS-like command line

Save the attached file
Extract the .bat files to your path

I like to have a C:\custom-path folder rather than throwing everything in system32

As a bonus I give you desktop.bat which allows you to CD to your desktop with just eight keystrokes (including the Enter key)
