manswitch grep silent
____________________________
In simple words
man <cmd> | grep "\-<switch>"
Eg:
man grep | grep "\-o"
This is not a standard method but works.
$ manswitch grep o -o, --only-matching Print only the matched (non-empty) parts of a matching line, with each such part on a separate output line. -q, --quiet, --silent Quiet; do not write anything to standard output. Exit immediately with zero status if any match is found, even if an error was detected. Also see the -s or --no-messages option. (-q is specified by POSIX.) ly mandates, for programs such as grep, cmp, and diff, that the exit $
e.g.
manswitch grep -o
This will take you to the relevant part of the man page, so you can see the description of the switch underneath.

man sed |grep -- -n
