title: CVS command to get the current revision number of file
body: <p>I need a simple way to get the revision of file using cvs. I can get it using the <code>CVS/Entries</code> file. It is not safe and I think there must be another way. <code>cvs log</code> prints too much than I need. How can I get only the revision number of some file using cvs commands.</p>
