De man man
:
-K, --global-apropos
Search for text in all manual pages. This is a brute-force
search, and is likely to take some time; if you can, you should
specify a section to reduce the number of pages that need to be
searched. Search terms may be simple strings (the default), or
regular expressions if the --regex option is used.
-w, --where, --location
Don't actually display the manual pages, but do print the
location(s) of the source nroff files that would be formatted.
Combinado:
man -wK 'Richard M Stllman'
Embora as páginas de trabalho normalmente tenham apenas Richard Stallman
, com uma quantidade variável de espaço entre as duas palavras, então um regex pode ser apropriado:
--regex
Show all pages with any part of either their names or their
descriptions matching each page argument as a regular
expression, as with apropos(1). Since there is usually no
reasonable way to pick a "best" page when searching for a
regular expression, this option implies -a.
Então:
man --regex -wK 'Richard *Stallman'
