Is that maybe because Unix commands don't execute when you aren't in a Unix environment.. ?

There are tools available such as Cygwin which gives linux environment in the Windows. First install it and then try to execute commands on it.

I too don't understand this concept but my TL is telling that it's possible. This is like a nightmare to me. Don't know how to resolve.

First learn the difference between DOS, Windows, and Unix.
