apropos - locate commands by keyword lookup
The apropos utility displays the manual page name, section number, subsection name, the keyword, and a short description for each manual page that contains keyword.
Each word is considered separately and the case of letters is ignored. Stemming on English words and section matching are also supported. Words which are part of other words are considered. For example, when looking for compile, apropos finds all instances of compiler as well. .
