title: unix command to grep for a particular word in a file
body: <p>i have a file that has a pattern like this </p>
  
  <pre><code>String(`TYPE',`ABC')dnl 
  String('TYPE',`BCD')dnl
  </code></pre>
  
  <p>and some other similar lines, so here i want this line  <code>String(</code>TYPE',<code>ABC')dnl</code> 
  i am using this command </p>
  
  <pre><code>cat file | grep TYPE
  </code></pre>
  
  <p>which gives me the desired output but when i am using the same command inside one script it throws one error</p>
  
  <pre><code>`cat file | grep TYPE`
  -bash: define(`TYPE',`ABC')dnl: command not found
  </code></pre>
  
  <p>what is that i need to modify in my command ?</p>
