in reply to Solaris and Icons
I have 22 years experience in IT and have recently been tasked with doing a lot of coding!
I'm surprised (actually, stunned) that somebody with 22 years of IT experience has not dealt with multiple operating systems (I've dealt with VMS, DOS, VM, MVS/XA, NOS/VE, Windows in its various incarnations, Unix in about a half-dozen variants, and one or two others too obscure to remember). Solaris is a one of the Unix derivatives, so it won't have DOS, although somebody who wanted to could probable whip up a BAT file interpreter in a few hours (I'm not that somebody).
I suggest you get a book like Learning the Unix Operating System, Fifth Edition.
Insisting on perfect safety is for people who don't have the balls to live in the real world.
