Alias to change path on the fly - ALTERNATIVE

[Guy Harris]

>Symlinks *not PORTABLE*????

No, symlinks *aren't* portable, at least not to all UNIX systems widely
used today.

>on a SUN?

Yes, they are supported on all flavors of SunOS (dunno about the
original Unisoft V7 for the Sun, but only people trying to be perverse
would call that SunOS), so the person who originally asked the question
could use them assuming they'd use them only on the Suns to which they
referred or on other systems whose OS supported them.

>You must be kidding.  Even SVR4 supports symlinks these days.

Sure does, but S5R3 as it comes from AT&T doesn't, and there are lots of
systems running S5R3 systems that haven't had symlink support added.

In other words, symlinks aren't portable to all UNIX systems widely used
today.  This may change in the future.
