Re: "cd" in bash script not being executed

[Aaron Stephanic <yakei410 at yahoo dot com>]

Sorry, it was my understanding of scripting that was broken.  My script 
wasn't permanently changing directories so I thought "cd" wasn't 
working.  But amazingly enough you actually can't permanently change 
directories in a script without a workaround... you have to "source" the 
script instead of execute it, or something along those lines... the 
reason being that scripts execute as child processes and can't change 
the directory of their parent process.  See this thread:
http://archive.lug.boulder.co.us/bymonth/1998.12/msg00151.html

That thread has a very interesting discussion of "cd" and even a 
suggestion on how to get rid of the need to type the command altogether, 
by the way.

So anyway, cygwin is working fine... well just like Unix and how it's 
supposed to in any case... which is fine.
