SVN-difference between lock on working copy of file and lock on repository file

What is the difference if I lock the file in the working copy that I have downloaded and the same file in the repository. The syntax is :

svn lock TARGET

So target can be URL for the file in repository and file in the working copy.

What is the differenc开发者_JAVA技巧e in both ways?

Locking a file through the svn lock command will always lock it in the repository.

If you use the 'file in your working copy' syntax (e.g. svn lock readme.txt), then you can only commit that file from that particular working copy.

If you use the 'URL in repository' syntax (svn lock http://myrepo/svn/myproject/readme.txt), changes to that file can not be committed from any working copy until the lock is removed.
