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: $!"; while (<INFO>){ chomp; print "\n$_&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.
