unix simulation

hello everybody.. im new to this forum.. i have sme basic knowledge about unix.. but not too much.. i would like to practice shell programs n perl using a unix simulator.. but then i don't know wht a unix simulator means? just a bald definition that it creates a unix working environment in windows is what i know.. but what does it actually mean? what if i create a file a.txt, say, where would it reside? plz anyone help me out in this..

thank you in advance.

Look into cygwin - this provides a unix-like environment but it uses the existing file system - like c:\

Untitled Document

thanx for the reply.. but cygwin hasnt got many commands.. so ive stopped using it..

Hello esash, can vmware virtual machine be a good choice for you?

--ilan

Try VirtualBox and install a virtual environment.

What exactly do you mean with "cygwin hasnt got many commands"? If I go by their package list you have pretty much everything that Linux has, from coreutils to KDE/GNOME
