Counting lines is surprisingly ambiguous

Two tools can count the same text and disagree, legitimately. The question is what happens at the end: if a file ends with a line break, is that a final empty line or just a terminator? The POSIX standard says every line ends with a newline, so a well-formed file with three lines has three newlines — and the classic Unix `wc -l` counts newline characters, reporting 3. A text editor showing a cursor position on line 4 is also correct, by a different definition.

This is why line counts differ between your editor, your terminal, and an import tool. Both counts are right; they answer different questions. What matters is knowing which convention your destination uses.

Where line counts actually matter

CSV imports are the big one: platforms quote limits in rows, and a file with trailing blank lines reports more rows than it has records — which is how you end up billed for a subscriber list padded with nothing. Counting lines before importing tells you whether your 500-row file is really 500 rows or 512 with 12 blanks.

Developers count lines to check log volume, to sanity-check that a generated file has the expected number of records, and to compare two exports quickly. The include-empty option here exists precisely because of the ambiguity above: turn it off to count real content, on to count physical lines. If your blank lines are unwanted, Remove Empty Lines clears them before you count.
