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.

Case sensitive — Linux is, and grading LS as ls would teach a falsehood.
Why
`usermod -s SHELL LOGIN` rewrites the seventh field of the user's line in /etc/passwd. The user-facing equivalent is `chsh -s /bin/zsh`, which an ordinary user may run on their own account but which only accepts shells listed in /etc/shells. usermod, run as root, has no such restriction. Note the case: -s sets the shell, uppercase -S is not a usermod option at all.
