I am trying to learn Shell scripting in UNIX. Could Any one please suggest on how to get UNIX account or any other free stimulator available for download on which I can practice Unix shell script?
Thanks,

Cant you install linux in some partition ? Little space is enough.
Or try Ubuntu from Live CD.
Download and install Oracle (former: Sun) VirtualBox and choose any Free UNIX (OpenSolaris, *BSD, Linux) to install.
Thanks for suggestion. I think cygwin is simplest for me. Can we practice shell script in cygwin?
thanks,

I have installed cygwin on a couple of different PC's. And yes, you can use to practice scripting commands - I use it to try and test certain commands.
Have fun...
cygwin's a good way to build a UNIX program in Windows without completely rewriting it; so cygwin lets a UNIX shell run inside windows. But cygwin is written overtop of windows and therefore still subject to many Windows idiosyncrasies(not allowed to open devices more than once; case insensitive filenames; and other things more obscure). Some basic UNIX features may be either implemented in a very strange and roundabout way, or missing entirely(how may consumer versions of windows even have working symbolic or hard links?) And you still don't have basic UNIX tools unless you install them too. It's little use to have a UNIX shell without ls and so forth.
So, cygwin is useful for building and running programs in Windows that'd otherwise require large amounts of modification. But as a teaching tool I think it stinks. It's not a standard environment; the lessons you learn won't necessarily have anything to do with real UNIX behavior.
Since limitations of cygwin were brought up, perhaps some clarification from me. I realize that cygwin is not a perfect simulator - it is not a unix environment, but a program that allows a user to execute many unix commands like ls, tr, cut, grep, paste, and so on.
For someone learning about commands and syntax and options, I believe ti to be a reasonable 'free' download for PC environments. I use the cygwin to solve many of my real-world problems, and also to simulate (and solve) issues brought up here for support.
So, the choice is yours - cygwin is free, and you can play with commands, or you can go out and download or buy other options. MKS software I used before, and felt it to more closely match 'true' unix - but you must buy the MKS software.
For me, I like to try 'free' options out first.
An alternative to cygwin is AT&T's Dave Korn's UWIN. See UWIN. It mainly uses the Win32 subsystem instead of the POSIX subsystem but is a good learning environment.
