title: What's the command mean? sed 's,^.*/,,'
body: <p>It's really un-usual using of sed for me.  I'm used to have <code>'s/pattern1/pattern2/g'</code>.  </p>
  
  <p>Can someone help me to explain it?<br>
  The input string is just like the following:</p>
  
  <pre><code>path1/path2/path3/fileA path1/path2/path3/fileB path1/path2/path3/fileC
  </code></pre>
  
  <p>the output is <code>fileA fileB fileC</code>.</p>
