Specific manual page for `bash` built-in commands

Maybe you already had the frustration of falling into a generic man page after typing

$ man builtin_command

where builtin_command is a bash built-in command like read or alias. As I realized a few minutes ago, there's a special help command for these functions, and this command is no other than... help.

So, if you want to get specific information about a bash built-in like alias, just type

$ help alias

and you'll be rocking.

Last, but definitely not least, the help command by itself

$ help

provides a complete cheat sheet for bash shell programming. This is invaluable for those that already know how to program, but need to get acquainted with bash.
