Good one.  I didn't think of that.

I looked into "which" a little bit.  It's pretty comlicated.  There are a 
number of options.  There is also the command "type" -- you often really 
need to use "type" instead of which.

Anyway, "which" can work for the script we've been working on but it seems 
that we need GNU which without these options to get a full path:

--show-dot --show-tilde

GNU on Solaris won't give the full path.  That's why we abandoned use of 
"which" in favor of cd with pwd.  Being able to use the builtins is nice 
because then you should be fully system independent and you'll only have 
to worry about bash version (maybe).
