% mkdir foo
% chmod 000 foo
% cd foo
foo: no such file or directory
% WHAT?
no match.
% touch bar
% chmod 777 bar
% bar


at this point, my .csrhc is being sourced...  and after that, it sits there..
shouldn't it only exec a csh if the first char is a #?  That's what it says
in OUR manual. 

Next fun item:

#!/bin/csh -f
echo -n "Go: "
set foo = $<
if ($foo =~ *\ *) echo true
echo done


This simple little ditty is supposed to check to see if there exists
a space in the variable "foo" that got it's value from the keyboard.
If there is no space, everything is fine -- it doesn't satisfy the
expression. If there IS a space, we get:

if: expression syntax.

fooey.
I found I had to enclose $foo in double quotes in order for the
expression to work. And it does.  

Can someone please explain to me what shell script does with strings
so that this is necessary?
