This is a short bash script, which I have written as a homework in my studies. It converts all files in parameters from DOS to UNIX or from UNIX to DOS, depending on their current style.

have fun with it!
I read this was a homework but you could also use unix2dos which is available via pakets like tofrodos.
Nice Blog. 🙂
hey gimi,
you are right, I know this. But unix2dos and vice versa was not allowed to use!
