Which command finds files under /data whose names end in .txt, .TXT or .Txt in a single search?
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.
The options
Not correct find /data -path '*.txt'
Wrong for this purpose. -path matches the pattern against the whole path find prints, and it is still case-sensitive; -ipath is its case-insensitive form.
Not correct find /data -name '*.txt'
Wrong. -name matches the file name case-sensitively, so it finds only the lowercase .txt files.
Correct find /data -iname '*.txt'
Correct. -iname is the case-insensitive form of -name, so all three spellings match.
Not correct find /data -type f '*.txt'
Wrong. -type f restricts results to regular files, but the trailing '*.txt' is not a test at all, so find rejects it as a stray argument (GNU find: 'paths must precede expression'). Nothing filters on the name.
Why
find tests the file NAME with -name and -iname, and the full path with -path and -ipath; the i-forms ignore case. Always quote the pattern, otherwise the shell expands the glob against the current directory before find ever sees it. Other tests you should know: -type (f, d, l), -size, -mtime, -user, and the actions -delete and -exec.
