What you really need on the top of the man page is an example of how to use this in daily life.
Apparently one does # dhcpcd5 wlxf428530bfc87 Browse Browse Browse for a few hours. Oh, time for bed. # dhcpcd5 -k wlxf428530bfc87 Wait, I forgot to email Georgio # dhcpcd5 wlxf428530bfc87 ... RM> Also see the -x and -M options and the section on Multiple interfaces. I don't know if I should use -x or -k in daily life. RM> A patch for better wording would be welcome :) RM> Because you started dhcpcd on interface wlxf428530bfc87 without -M, all RM> exit operations need to be given the same interface. Well then all I know is saying > -k, --release [interface] > This causes an existing dhcpcd process running on the interface > to release its lease and de-configure the interface regardless of > the -p, --persistent option. If no interface is specified then ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > this applies to all interfaces. If no interfaces are left run- ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ > ning, dhcpcd will exit. is wrong! Also > # dhcpcd5 -k > dhcpcd not running Should say "dhcpcd not running on interface '' but maybe running on other interfaces." or something. RM> The idea was that the dhcpcd package (@ version 3 iirc) would be retired Oh I see...
