Agreed: This is as per unix but in unix I can do test to see if the
directory \ file I am copying exists in the destination.
How can I simulate that with Subversion.
Is svn ls the only method or could someone suggest other alternatives.
Is there a hook someone else already has ...

If you're talking about parsing for the message "svn: URL 'http://
whatever/branches/whatever' non-existent in that revision" then I would
advise against that. Sure, it could change.
"svn ls <nonexistent_url>" does return an exit status of 1, so I would
recommend using that instead. I'm using Subversion 1.4.4; if you're
using an earlier version, you should probably upgrade. This may have
been fixed recently.
