title: Perl script to merge multiple files line by line
body: <p>Can anyone please help me with writing a Perl script which can take as input 5 text files and create a new text file with merging each row of all 5 files. 
  Should this be done by opening 5 read streams at a time or like java some random file reader is available in Perl ?</p>
  
  <p>Thank You!</p>
