An audit asks for every regular file under /srv larger than 100 MiB. Which command produces that list?
LPIC-1 Exam 101-500, objective 103. GNU and Unix commands medium
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.
The options
Correct find /srv -type f -size +100M
Correct. The M suffix means mebibytes, and the leading plus means strictly greater than, so only files above 100 MiB are listed. -type f restricts the result to regular files.
Not correct find /srv -type f -size 100M
Wrong. Without a sign the test is for exactly 100 units, and since find rounds the size up to whole units this matches only files between 99 MiB and 100 MiB.
Not correct find /srv -type f -size +100
Wrong unit. With no suffix the unit is a 512-byte block, so this matches everything over about 50 KiB — nearly the whole tree.
Not correct find /srv -type f -size +100k
Wrong unit. k is kibibytes, so this matches files larger than roughly 100 KiB, a thousand times smaller than the threshold asked for.
Why
The -size suffixes are c for bytes, k for KiB, M for MiB, G for GiB and b — the default — for 512-byte blocks. find rounds each file's size UP to the next whole unit before comparing, which is why an exact match is rarely what you want and +n or -n is the normal form. -type takes f for regular files, d for directories, l for symbolic links.
