Although this is not an SGI-specific issue, I would like to point
out that this approach can be *very* slow for large directory trees
since the 'find' program forks off a 'chown' program for each file
that it finds.

A much more efficient approach is to use xargs:

	find . -print | xargs chown $username

This will bundle up the names into larger groups and call 'chown'
on the groups.
