Ah!  Yes, I've run aground on those rocks too.  What would have served 
me well, and avoided the majority of my questions here, is some Big Book 
of Shell Gotchas.  Especially useful for a guy like me coming from DOS 
and only having that, and C, as my notions of what programming 
environments are like.  What's frustrating is that I learn something and 
six months latter I've forgotten.  I sure wish we could scan the 
archives, I'd be going back and checking my own previous questions -- 
like just now, I knew I'd asked about '(q)' previously.

I don't!  All I know is that it got me into trouble.
