title: What's wrong with my `adb logcat ...` command?
body: <p>I just want to see <code>logcat</code> output for <code>MyTag</code> that my app outputs.  I thought this would be the command to run ...</p>
  
  <pre><code>$ adb logcat MyTag:*
  </code></pre>
  
  <p>... but nothing gets filtered and the output is the same as if I had executed:</p>
  
  <pre><code>$ adb logcat
  </code></pre>
  
  <p>What am I doing wrong?</p>
  
  <p>Thanks</p>
