title: Is there a unix command line utilty for 'mapping' by line?
body: <p>I have an input stream, and I want to "map" to output lines. For instance, if my input stream were the files nums, I'd want that this syntax</p>
  
  <pre><code>$ cat nums
  9534
  2343
  1093
  7023
  $ cat nums | map ./myscript $0
  </code></pre>
  
  <p>would be equivalent to</p>
  
  <pre><code>$ echo 9534 | ./myscript
  $ echo 2343 | ./myscript
  $ echo 1093 | ./myscript
  $ echo 7023 | ./myscript
  </code></pre>
