Before writing a conversion script you need to confirm that the local iconv installation knows the encoding named CP1252. Which command lists every encoding iconv can convert between?
LPIC-1 Exam 102-500, objective 107. Administrative tasks 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 iconv -l
Correct. -l (--list) prints all known character encoding names, including the aliases each one answers to.
Not correct iconv -f CP1252
Wrong. -f names the input encoding for an actual conversion. With no -t and no input file the command waits on standard input rather than listing anything.
Not correct locale -a
Wrong. locale -a lists the locales that have been generated on the system, such as de_DE.UTF-8. Locales and encodings are related but distinct; a locale name is not an iconv encoding name.
Not correct file -i notes.txt
Wrong. file -i guesses the MIME type and charset of one particular file. It tells you nothing about what iconv supports.
Why
iconv converts between encodings named on the command line with -f (from) and -t (to); -l enumerates the set it was built with. The closest neighbour is `locale -m`, which lists the charmaps known to the locale system rather than iconv's own conversion table. Encoding names are matched case-insensitively and most have several aliases, which is why the list is long.
