Some notes:

• Each line is in one element of the array.
• You want to delete the last line.

Sounds like you want to delete the last line of the array.

Now, just because you do that, you aren't actually affecting the file. You would have to write back to the file what the file should now look like.

use strict;
use warnings;

use IO::File;

my $filename = 'file.txt';

my $in_fh = IO::File->new($filename)
    || die "Can not open '$filename' for reading: $!\n";
my @records = <$in_fh>;
$in_fh->close;

print "@records\n";
pop @records;

my $out_fh = IO::File->new(">$filename")
    || die "Cannot open '$filename' for writing: $!\n";

print $out_fh, @records;

$out_fh->close;

You can do this in a 1-line from the command-line.

perl -pi -e 'last if eof()' file.txt
