these code have written in perl. code not working fine. giving tab space every nextline. dont need tab space every new line.let me show how output is.

          name         contact        email                        samy            32344245            hyte@some.com                        alex            231414124           coool@some.com

this how see mool.txt file.the first line working fine.but nextline i'm facing tab space.i trying find out bug is.can please let me know code going wrong?i have gone through many times unable figure out.thank you

as asked im showing input file

        "name","contact","email"         "samy","32344245","hyte@some.com"

put statement inside while loop. chomp should first line after reading line file. remove unwanted spaces.

use strict; use warnings; open(file4,"cool.txt"); open(file6,">./mool.txt");  while (<file4>) {      chomp; #this remove unwanted spaces      @array = split(/,/,$_); #$_ represent line read      print file6 ($array[0]);      print file6 ("\t");      print file6 ($array[1]);      print file6 ("\t");      print file6 ($array[2]);      print file6 ("\n");  }
