title: how to remove a version in clearcase
body: <p>I want to check out a directory , let's say <code>/vobs/myvob/src/</code> to add a new file in this directory. But by mistake rather than checked out <code>/vobs/myvob/src</code> I checked out <code>/vobs/myvob/scr/</code> and even worse checked in it. Then directory <code>scr</code> has a new version :  <code>scr@mybranch/1</code>  (let's say I'm working on branch <code>mybranch</code>)</p>
  
  <p>After realized that I've made a mistake, I remove the newly created version by:</p>
  
  <pre><code>ct rmver scr@myranch/1
  </code></pre>
  
  <p>then use <code>ct ls parent_dir_of_scr</code> to do the double check  and I found although <code>scr@mybranch/1</code> disappeared, <code>scr@mybranch/0</code> is still there .<br>
  Not 100% sure but I'm afraid I should not try to remove that version in the same way , cus it might let clearcase remove a version in main as well.<br>
  So my question is how should I do a totally "clean up" in this situation . </p>
  
  <p>Need your help . thanks in advance .</p>
