It's hard to tell exactly what you mean when you refer to "shell command", particularly because you don't show us anything you've tried, but here's a simple Perl snippet that shows how to do what you want.

#!/usr/bin/perl

use strict;
use warnings;

open my $fh, '<', 'file.txt' or die "Can't open file: $!";

while ( my $line = <$fh> ){
    chomp $line;
    # do stuff
    print "$line\n";
}
