title: How to create and save a bash script
body: <p>The teacher never explained us anything about unix and bash. He told us something about the history. Then he said how to fill in an IP address in a program called putty, which is the shell we used to work on the server. He basically gave us 7 series of exercises. We also had a book that was pretty useless. I mostly used internet and SO to help myself out, along with the commands I knew from DOS and the man/info pages.</p>
  
  <p>The question is, what is the <strong>preferred</strong> text editor to make scripts? Internet says any will do but I know only <code>cat</code>. And then, how do I even begin? What I need is a crash course or something. I'm sorry I know this isn't the best kind of question to ask here but it's all I can think of atm. Don't blame me, but please do bash the teacher (pun intended).</p>
