title: Perl: Calling a perl script from another
body: <p>I have a perl script which calls another script. I am calling it using backticks and passing argument to that script and it works fine.</p>
  
  <pre><code>`CQPerl call_script.pl $agr1 $agr2 $arg3`;
  </code></pre>
  
  <p>But please suggest if there is another better way to do so. How can I check if the script errored out because of the calling script or the script that was called. How do I do that check from the calling script itself?</p>
