Bash And Scripting
The Bash Reference Manual
Perhaps in response to the usability issues found
in the bash man page, the GNU Project produced the
Bash Reference Manual. You can think of it as the
bash man page translated into human readable form.
While it lacks a tutorial focus and contains no usage
examples, it is much easier to read and is more
usefully organized than the bash man page.

both extensively document the features found in bash.

users. There are also several fun to read rants.

chaotic, it does contain useful information.
