A single find command must report regular files under /home that are larger than 100 MiB and owned by the user carol. Which THREE predicates express those three requirements?
LPIC-1 Exam 101-500, objective 104. Devices, Linux filesystems, filesystem hierarchy standard 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
Choose 3.
Correct -type f
Correct. f selects regular files, excluding directories (d), symbolic links (l), block devices (b) and the rest.
Correct -size +100M
Correct. The M suffix means mebibytes and the leading plus means greater than, so this matches files above 100 MiB.
Correct -user carol
Correct. -user tests the owning user, and it accepts either a name or a numeric UID.
Not correct -type d
Wrong. d matches directories, which is the opposite of the requirement and would also make the size test close to meaningless.
Not correct -size +100c
Wrong unit. The c suffix means bytes, so this matches almost every file on the system rather than only the large ones.
Not correct -group carol
Wrong attribute. -group tests the owning group. Ownership by the user carol and membership of a group named carol are separate facts.
Why
Predicates written side by side are joined by an implicit AND, so `find /home -type f -size +100M -user carol` requires all three to hold. The -size suffixes matter and are easy to lose marks on: c is bytes, k kibibytes, M mebibytes, G gibibytes, and no suffix at all means 512-byte blocks, with the value always rounded up to the next whole unit. The same +/- sign convention that governs -mtime governs -size.

Reading one question is not practice. The trainer will draw a short set from objective 104 and space the ones you get wrong.
