in reply to formatting print output from array

The problem is that when you read in the lines, each ends with a newline. So you have to remove those with chomp. I'm guessing the problem you had was running chomp on your output, not on your input.

Incidentally, unless there's a reason you need all of the input in an array, you might find it a lot more efficient to deal with each line as it comes in. That is, 

#!/usr/bin/perl -w
use strict;
my $file = '/home/steven/x.x-sort';
open(INFO, $file) or die "Couldn't open $file: $!";
while (<INFO>){
        chomp;
        print "\nhttp://website.org/session2?ip=$_&email=you%40there.c
+om\n";
}
close(INFO) or die "Error writing $file: $!";

If for whatever reason your code is more complicated and you really do need the @lines array, you need to chomp it, as in chomp(@lines = <INFO>), which will remove the trailing newlines from each line.

    You can golf the loop down like this: 
    while (chomp(<INFO>)){ print "\nhttp://website.org/session2?ip=$_&emai
+l=you%40there.com\n" }

      Or golf the whole thing to:

      (@ARGV, $/) = '/home/steven/x.x-sort';
$_ = <>;
s[.+][http://website.org/session2?ip=${&}&email=you%40there.com]g;
print;
