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
