Subject: Re: Strange cd/CDPATH behavior

References: <007001c027d7$62420680$c4acb018 AT home DOT com>

Others have commented on the use of cygpath, and I have seen your
response, so I will not add to that part of the discussion.

Regarding the CDPATH variable, I just did some experiments with various
types of paths.  It looks like it will print the path cd'd to, if there
is a possibility that the path was the result of a cd to one of the
other directories in the variable.  Put another way, if the path
argument to cd is either absolute (begins with a slash) OR begins with
either a dot or a dotdot, there is only one place to go.  But a 'cd tmp'
could get you to /tmp or /var/tmp (or others, if present).

And this happens both interactively and in scripts.  I had this problem
with a Solaris ksh script (/usr/bin/dircmp), when I had CDPATH set, when
it changed directory I'd get this 'spurious' output.  I ended up having
to unset CDPATH when I ran this script.

And finally, by the above criteria, the dos directory names that start
with a drive letter are going to match the "print the new current
directory" case and will generate output.
