This rules out at least some filesystem checks.

I agree with Manuel that it is better to check for the shell instead
of file system. Checking for # seems good enough. There is a windows
counterpart -- check for % : `echo %comspec%` will output literal
"%comspec%" in unix and will output something else in windows.
Looking at output of `echo` (without arguments) is also good.
Or you can just test for working copy/cp as Joseph Wright have
