Unless you are storing the lines you are reading this will only read
one line at a time. You should also use the new (eight year old)
style lexical filehandles and the three argument version of open:
open my $source, "<", "/tmp/file"
or die "could not open /tmp/file: $!";
while (my $line = <$source>) {
#do stuff with $line
}
