title: format the shell script
body: <p>I have some 1000 lines shell script with all the kepywords</p>
  
  <p>if/else, while, HERE document</p>
  
  <p>Can anyone tell the best way to format the script, so the script looks good.</p>
  
  <p>I was trying VG= in vim but that displaces HERE document content as well.</p>
