How can I get the manpage-like help information of a service?

$ rpcinfo 

   program version netid     address                service    owner

    100000    4    tcp6      ::.0.111               portmapper superuser

    100000    3    tcp6      ::.0.111               portmapper superuser

    100000    4    udp6      ::.0.111               portmapper superuser

    100000    3    udp6      ::.0.111               portmapper superuser

    100000    4    tcp       0.0.0.0.0.111          portmapper superuser

    100000    3    tcp       0.0.0.0.0.111          portmapper superuser

    100000    2    tcp       0.0.0.0.0.111          portmapper superuser

    100000    4    udp       0.0.0.0.0.111          portmapper superuser

    100000    3    udp       0.0.0.0.0.111          portmapper superuser

    100000    2    udp       0.0.0.0.0.111          portmapper superuser

    100000    4    local     /run/rpcbind.sock      portmapper superuser

    100000    3    local     /run/rpcbind.sock      portmapper superuser

$ man portmapper

No manual entry for portmapper

How can I find out the actual program/executable/command name for a service? For example portmapper isn't a command name for portmapper service, otherwise man portmapper would likely works.

Thanks.

Did you mean systemd service? Why this is not included in the question? If yes, look at the .service files. Or just use systemctl cat xxx.service which follow systemd unit file override rules.

@炸鱼薯条德里克 better yet, for a systemd service you can try systemctl help. But this is RPC so it’s not systemd services.

In some cases, apropos (or man -k) will find the relevant manpage. That’s not the case here, but a full-text search using man -K will lead to the rpcinfo(8) manpage which says that

Version 2 of the rpcbind protocol was previously known as the portmapper protocol.

So the command you’re looking for is rpcbind.
