RH124 Ch 4: Find Answers in man Pages and Docs

In the exam there is no internet, only the documentation on the system. Practise finding answers in man pages and `/usr/share/doc`, and write each answer into `~/answers`.

Tasks

1. Save the man page section number that documents the format of the /etc/passwd file to ~/answers/passwd-section.txt (just the number).
2. Using man ssh-keygen, find the short option that chooses the type of key to create and save it to ~/answers/keytype-option.txt.
3. Using man -k, find the command whose man page summary is "OpenSSH secure file copy", and save the command name to ~/answers/copy-command.txt.
4. Copy the example key file shipped in the chrony package's documentation directory to ~/answers/.
