Thanks for trying things, but...

The original poster is using the -1 option which attempts to get to the
appropriate directory without executing the intermediate script (xhere). As
you've seen this has problems with quoting which are unique to each of the
shells, since it is the shell that is evaluating the argument. This method also
has problems accessing network paths and starting ash and tcsh as noted on the
man page.

I've tested the other start option (-2), and that correctly goes to the path
"\\Minime\$@dave's `stuff". That contains an apostrophe, a backtick and what
could be interpreted as a shell parameter, all on a network path. I'm not
entirely sure why this works, but I suspect it has to do with the lack of
recursive parameter expansion. But don't quote me on that :)

Since the single quotes prevent shell expansion and things, I think that they
are most appropriate for the -1 option. I will note the limitation on entering
directories containing apostrophes in the man page.

The -2 option is the default, so I don't see this being a major issue.


Regards,

Dave.
