Can't remember it. Tried to google it with no luck. I encountered it last week but the browsing history is wiped.

Here's what that command does. You just write it in terminal with some word. It will search through all the manuals from repository and print out the list of matches with short description.

You are looking for apropos or man -k.

From man man:

man -k printf
           Search the short descriptions and manual page names for the 
keyword printf as regular expression.  Print out any matches.  
Equivalent to apropos -r printf.

From man apropos:

apropos - search the manual page names and descriptions

Check man apropos and man man for details.
