title: How would I parse through a man page to quickly find info about a program option ("-I")?
body: <p>I'm trying to build freeglut, I just want to debug a bash script option and I need to find out what specifically <code>-I</code> and <code>-L</code> gcc compiler options do. I shouldn't have to go through 10,000 freaking lines of text.</p>
  
  <p>I just tried the following</p>
  
  <pre><code>man gcc | cat &gt; gcc.txt
  grep "-I" gcc.txt
  </code></pre>
