Does nobody use info?
So much more in depth than any manpage.
Granted it doesn’t contain every app installed, but it gives very detailed and very verbose explanations, examplea, options, use cases, caveats, warnings, etc, for all of the most essential commands and functions
$ info
In the program these are basic commands :
-I # sets searching to always case insensitive -very necessary (upper case I)
/ # search for pattern
n # search forward
N # search back
You can also search from command line using
Info -k [pattern]
Badgers? Badgers?
We don’t need no stinkin’ badgers!
