title: How can I read one line at a time with C shell in unix
body: <p>I try to make a small script, using c shell, that will take a file made of several lines, each containing a name and a number and sum all numbers that a have certain name. How can I put into a variable the next line each time?</p>
  
  <p>the summig part I do by: (after I'll be able to get a full line to $line)</p>
  
  <pre><code>set line =($line)
  @ sum = $sum + $line[2]
  </code></pre>
