How to remove all deleted files from repository?

I have a script in which I add all new files before to commit my working copy to my repository with this line:

svn status | grep ^\? | awk '{print $2}' | xargs svn add

I now want to add a line that delete from repository all deleted files in my working copy. In other terms, I cannot specify them one by one, and I need to detect them with svn status and then automatically remove them. However the line doesn't work.

svn status | grep ^\! | awk '{print $2}' | xargs svn --force delete

As you can see I've replaced

"?" with "!" and

"add" with "--force delete"

Could you tell me why it doesn't work ?

ps. I know it is a risky procedure. I've already discussed all about it. thanks

thanks
