Posted on 2014-12-10

I wrote a perl script that does the following things.

1) Inputfile is provided
2) split input file using \n
3) if a line starts with "EMP" string then split the line with "|" and get the first word which is EMP ID
4) there might be multiple lines that starts with EMP so get all EMP ID's and out put those to a txt file

I wrote the below script but this one is not working not sure where did I made the mistake.

Sample Input file:

This should mostly fix your script.  The problem is your handling of the file.  "while (<X>)" is already reading the file line by line.

With the "for 2.." are you trying to skip the first line of the input file, the first two lines, or something else?
Also see the comments in the script about your output lines - they almost certainly aren't doing what you want.

use strict;
use warnings;
use Pod::Usage;
use Getopt::Long;

my $helpme = 0;
my $man = 0;

my $inputFileName = 'C:\\Testfile.txt';
my $outputFileName = 'C:\\Testfile_Amt.txt';

my $errorcode = 0;
my $DEBUG=0;

if(exists $ENV{DEBUG}) {
	$DEBUG = ($ENV{DEBUG} eq "") ? 0 : $ENV{DEBUG};

GetOptions('help' => \$helpme, 'man' => \$man, 'infile=s' => \$inputFileName, 'outfile=s' => \$outputFileName) or pod2usage(2);

pod2usage(1) if $helpme;
pod2usage(-verbose => 2) if $man;

die 'No input file name specified!' unless $inputFileName;
die 'No output file name specified!' unless $outputFileName;

open(INFILE, '<', $inputFileName) or die "Could not open input file: $!";
open(OUTFILE, '>', $outputFileName) or die "Could not open/create output file: $!";

while(<INFILE>) {
	### possible skip of first line or two
	if (/^EMP\|([^|]+)\|/) {
		my $empID = $1;
		### what are you trying to do with these lines?
		### they almost certainly don't do what you want
	    #print OUTFILE "I " . "0" x ($empID). "\n";
   	    #push(@employee, $empID);
		print OUTFILE "I ", $empID, "\n";

close INFILE;
close OUTFILE;

exit $errorcode;
