	I didn't/don't know much about bash--other that it seems to be 
	everywhere.  Last night I spent several hours using my own hack
	that translater the csh aliases to bashrc-type aliases.  Finally
	threw in the towel.

	The last one, .inputrc, is a noop to my brain.  And yes, I just
	had my second cup of coffee!  IS there any cheatsheet URL that
	'splains the readline init'z'n stuff?

	Looks at lot like my zsh usage.

	I have always ripped off somebody's prompt and then modified it
	to what fits my needs.  Last night I kept running into problems 
	with the PATH and the aliases.  Each re-edit I did I figured it
	would be just-another-minute before bash worked.  Nope, nada,
	zip.  Finally got smart and :quit.
