In Perl, you can use regular expressions (regex) with the `m//` operator to match patterns in a string. Here's an example of how you might extract phone number, pin code, and year from a text file:

open(my $fh, '<', 'file.txt') or die "Couldn't open file!";

while (my $line = <$fh>) {
if ($line =~ /(d{6}) (d{10}) (d{4})$/ ) {
print "Phone Number: $2nPin Code: $1nYear: $3n";
}
}
