Actually my code looks something like this
svn add --force .
svn commit -m "daily prd commit"

This adds everything under the current directory recursively and then
commits everything.

Looks like after I installed UnixUtils and changed the code slightly

svn st --depth=infinity | sed -n "s/^\! //p" | xargs svn rm

it seems to work. What if the file name has a spaces in it? Does
anyone have a regex for that?

What I mean is if I commit things immediately, and the file happens to
change several times a day, I only want the last change in the
repository. I don't necessarily want all the intermediate revisions.
