title: Reading file line by line (with space) in Unix Shell scripting - Issue
body: <p>I want to read a file line by line in Unix shell scripting. Line can contain leading and trailing spaces and i want to read those spaces also in the line.
  I tried with "while read line" but read command is removing space characters from line :(
  Example if line in file are:-</p>
  
  <pre><code>abcd efghijk
   abcdefg hijk
  </code></pre>
  
  <p>line should be read as:-
  <code>1) "abcd efghijk"
   2) " abcdefg hijk"</code></p>
  
  <p>What I tried is this (which not worked):-</p>
  
  <pre><code>while read line
  do
     echo $line
  done &lt; file.txt
  </code></pre>
  
  <p>I want line including space and tab characters in it.
  Please suggest a way.</p>
