title: How to run multiple c++ executable at batch?
body: <p>I have a bunch of C++ executable that I want to run in batch. Suppose I have three executables "101", "233", "330", I try to run them like:</p>
  
  <pre><code>ls | grep '^[0-9]*$' | xargs -n1 ./
  </code></pre>
  
  <p>But, I got an error </p>
  
  <pre><code>xargs: ./: Permission denied
  </code></pre>
  
  <p>Is there any way I can run those executables with one-liner instead of writing a shell for loop?</p>
  
  <p>I doubt my simple inquiry should be answered somewhere, but I have no luck finding it through google. </p>
  
  <p>Thanks!</p>
