Is there a specification for bash? [closed]

Question

like other languages?

I googled it and came up with

https://www.google.com/?gws_rd=ssl#q=bash+specification

which did not list any specifications, just manuals and guides.

Thanks,

Answer 1

IEEE 1003.1 (“POSIX”) defines a standard “Shell Command Language”. You can find the 2016 edition here.

GNU Bash is an implementation of that language, with many extensions. The only specifications for the extended bash language are the bash reference manual and the bash source code.

Answer 2

I would consider the manual to be the spec. Bash Manual
