$ 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.

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.
