title: word count of each line in a script
body: <p>I have to write a script to read each line using a while loop and count the number of words in each line. So far i can get the total number of lines and the text for each on its own line. I am having trouble using the wc -w command to count the number of words for each line and display it. when i put it on the same line as the printf statement is gives an inaccurate count. I have to pipe the text tile to the script so it will count the words, for example: cat file.txt | word_count.sh</p>
  
  <p>any suggestions?</p>
  
  <p>code:</p>
  
  <pre class="lang-shell prettyprint-override"><code>#!/bin/bash
  line_num=1
  
  while read line;do
    printf "line $line_num: $line"
    ((line_num++))
  done
  </code></pre>
  
  <p>results:</p>
  
  <pre class="lang-none prettyprint-override"><code>cat imagine.txt | word_counts.sh 
  line1: magine there's no countries 
  line2: It isn't hard to do 
  line3: Nothing to kill or die for 
  line4: And no religion too 
  line5: Imagine all the people living life in peace 
  </code></pre>
