title: bash -- kill command script
body: <p>I'm looking into writing shells scripts as a prerequisite for a class and would like some help to get started. I'm currently doing a warm up exercise that requires me to write a shell script that, when executed, will kill any currently running process of a command I have given. For this exercise, I'm using the 'less' command (so to test I would input 'man ps | less'). </p>
  
  <p>However, since this is the first REAL script I'm writing (besides the traditional "Hello World!" one I've done), I'm a little stuck on how to start. I'm googled a lot and have returned some rather confusing results. I'm aware I need to start with a shebang, but I'm not sure why. I was thinking of using 'if' statement; something along the lines of </p>
  
  <pre><code>if 'less' is running
  kill 'less' process
  fi
  </code></pre>
  
  <p>But I'm not sure of how to go about that. Since I'm incredibly new at this, I also want to make sure I'm going about writing a script correctly. I'm using notepad as a text editor, and once I've written my script there, I'll save it to a directory that I access in a terminal and then run from there, correct?</p>
  
  <p>Thank you very much for any advice or resources you could give me. I'm certain I can figure out harder exercises once I get the basics of writing a script down. </p>
