And if the file contains 0 newlines? Update: Or, you want newline characters to be include in your tuples.

Then read fixed sized blocks instead of lines:

C:\test>perl -e"BEGIN{$/= \1024}" -nle" rand() < 0.1 and print length( +)" 986831-01.dat 1024 1024 1024 1024 1024 C:\test>perl -e"BEGIN{$/= \1024}" -nle" rand() < 0.1 and print length( +)" 986831-01.dat 1024 1024 1024 C:\test>perl -e"BEGIN{$/= \1024}" -nle" rand() < 0.1 and print length( +)" 986831-01.dat 1024 1024 1024 1024

With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
"Science is about questioning the status quo. Questioning authority".
In the absence of evidence, opinion is indistinguishable from prejudice.
