title: When learning Java, how important is it to know Unix well?
body: <p>Other than the Java language itself, you have to learn the java framework.   Similiar to how you have to learn the .net framework in addition to the language (C#/VB).</p>
  
  <p>How important is it to know unix? Or rather, what unix areas should one focus on?</p>
  
  <p>Seeing as many people run java based applications (desktop/web) on unix boxes, <strong>what sort of unix skills do you need</strong>?  Are we just talking basic directory traversing, creating files, etc or is there much more to it?</p>
