You have to read more than the first lines of a man page to learn how
to use a command.
"man ps" has "ps [options]" and "man nmap" has "nmap [Scan Type...]
[Options] {target specification}"...
See the last lines of my earlier email to display the fields with tab

Also:
man journalctl
man systemd.journal-fields
