apropos

The apropos command line tool is used to search the manual page descriptions for keywords or expressions related to a specific topic. When a certain command or concept is not known, apropos helps identify relevant commands and manuals that may provide the necessary information.

By running the apropos command followed by a search query, the tool will scan the various manual pages and display a list of commands, functions, or topics that match the given query. The search is primarily performed on the name and short description sections of the manual pages.
