Re: how to update a file's copy in another directory

This won't work, because 'svn up' only moves through revisions (time).

But its cousin, 'svn switch', moves through revisions (time) *and*
paths (space.)

So something like

    svn switch -r2 http://.../dir1/file dir2/file

Now you have a working copy with 'mixed' URLs. You've essentially
moved the one file to a different branch. This will give what you
want, at least temporarily.

Unfortunately, because it's an *old* version of the branch (r2), if
you run 'svn up' on the whole working copy, it will try to update
dir2/file to the latest revision of dir1/file (i.e. move it forward in
time, without changing the file's URL.) There's no way to make it
'sticky'.

Correct. 'svn cp' will never overwrite anything.

You can't checkout a foreign URL into a working copy of a different
URL.

That's the only solution. If you want the change to be *permanent*,
you have to "replace" the file (delete file, add new one). And it can
be done in a single commit:

 $ svn rm dir2/file
 $ svn cp -r2 http://.../dir1/file dir2/file
 $ svn status
 R + dir2/file # the 'R' is for (R)eplace

 $ svn commit
