title: Argument pass to file read in as 0
body: <p>I have a script:</p>
  
  <pre class="lang-bash prettyprint-override"><code>#!/bin/bash
  echo "You chose $1 and $2 "
  if [[ $1 -eq 0 || $2 -eq 0 ]]
  then
    echo "You didn't chose argument"
    exit 1
  elif 
  
  ...
  exit 0
  </code></pre>
  
  <p>and in terminal I tried :</p>
  
  <pre><code>./Path/to/script argument1 argument2
  </code></pre>
  
  <p>In result I get:</p>
  
  <pre class="lang-none prettyprint-override"><code>You chose argument1 and argument2
  You didn't chose argument
  </code></pre>
  
  <p>How it is possible that i the same moment it can return both arguments correct and see them them as 0? </p>
  
  <p>What is wrong here?</p>
