What is a mountpoint?

A mount point is a directory on a file system that is logically linked to another file system. Mount points are used to make the data on a different physical storage drive easily available in a folder structure. Mount points are fundamental to Unix, Linux and macOS. Windows can use mount points, but it is not common.

Special man command

If you use less as pager for man you can try

LESS="+/^\s+-b" man wget

where

1. + symbol to execute next operation after less has opened
2. / command to start search
3. ^\s+-b regexp to match -b from start of line

So if you like you can arrange the apropriate function for shell

function rman {
#USAGE: rman programm.name option.to.search (with "-" symbol)
LESS="+/^\s+$2" man "$1"
}

and add it into ~/.bashrc for example.
