I finally solved it :) Thank you all, great community!
here's my solution:
#! usr/bin/perl
use strict;
use warnings;
use IO::File;
my @out;
my @file_names = ("output1.txt", "output2.txt", "output3.txt");
my $i = 0;
my $file;
if ($#ARGV < 1){
die "Usage: $0 Argument1 Argument2 ... \n";
}
foreach $file (@ARGV){
open (READ, $file) || die "Cannot open $file: $!.\n";
$out[$i] = IO::File->new( ">$file_names[$i]" ) || die "Cannot open
+ $file_names[$i]: $!.\n";
while (my $line = <READ> ){
print {$out[$i]} "$line";
}
$i++;
}
