LPIC-1 Exam 101-500, objective 103. GNU and Unix commands easy
Machine-checked — no person has signed for it. This question was read against the source cited below by an automated pass, which found no contradiction. That is a weaker claim than it sounds: the same kind of process wrote the question, so it can confirm its own mistake.
Treat it as a good draft rather than as settled fact, and read the source below before you rely on it. It is not used in mock exams here — only questions a person has signed for are.
How these questions are written — where each question comes from, what the verification ledger records, and what happens when one is found wrong.
Answer
Type the answer.
Accepted answers
wc -l report.txtwc --lines report.txt
Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
wc prints line, word and byte counts. -l restricts it to lines, -w to words, -c to bytes and -m to characters. With a file argument the count is followed by the file name; if you pipe the data in instead (wc -l < report.txt) you get the bare number, which is handy inside scripts.
Where this comes from

- What it says

Reading one question is not practice. The trainer will draw a short set from objective 103 and space the ones you get wrong.
