No reason to fork another process by going out to the shell to run a sed command. Perl has several ways to get a line on a specific line number.
This is probably how I'd do it.
use strict;
use warnings;
use autodie;
my $file = 'somefile.txt';
open my $fh, '<', $file;
my $line;
while ($line = <$fh>) { close $fh and last if $. == 4 }
print $line;
