SVN update returns nothing, while it should

First some background information;

• I've set up my SVN repository on my local server at home using VisualSVN Server.
• Using SSH on (or via php/shell script), i am able to check out a folder from this repository to the webserver, all goes well.
• Also updates and other svn commands execute normaly and return their messages.

Now comes the problem, and I'm struggling with this for a few days now.

Before I execute the checkout command svn co http://server_home/folder, I want to make sure no conflicts are going to happen, so I execute svn status [folder_on_webserver].

But this doesn't return the result as expected, it returns nothing. When I execute * svn status --show-updates [folder_on_webserver]* it returns the following:

       *            newfolder
       *开发者_高级运维       13   anotherfolder
       *       13   yetanotherfolder
       *       13   .
Status against revision:     16

As you can see it misses the svn codes (A,U,D).

Does somebody knows why the svn update command and the svn codes doesnt work?

svn status will not work before svn co. You need to have your repository checked out before you can check the status. Use svn up to update.
