in reply to perl

Assuming by 'empty' you mean 'containing only space characters':

open FILE, "file.txt"; my $count; while (<FILE>) { $count++ unless /\S+/; } close FILE; print $count;

    Just as a footnote, if you do not want to count lines that contain a tab or some other such whitespace, you can substitue /\S+/ with /^$/ in either this code or in Fastolife's below

    This is the best solution I would use, though /\S/ is sufficient.
