title: linux "lessPATH" similar to $CDPATH and $PATH
body: <p>I like the flexibility and how easy it is to execute commands from any directory in <strong>$PATH variable or $CDPATH</strong> to change directory. </p>
  
  <p>But is there an easy way to "less or open a file" from a <strong>list of directories</strong> you often visit.</p>
  
  <p>Say you have log files in a different dir and other frequently visited directories in another. A <code>less file1</code> command should look for the file1 in a list of directories defined like a $PATH  or $CDPATH variable.</p>
