http://explainshell.com/ is a nifty little website created by Idan Kamara that takes difficult Linux command line man pages and one liners and makes them much easier to understand by breaking down a command into it’s respective parts.
This site contains 29761 parsed manpages from sections 1 and 8 found in Ubuntu’s manpage repository. A lot of heuristics were used to extract the arguments of each program, and there are errors here and there, especially in manpages that have a non-standard layout.
Check it out!
