Re: Early history of Bash

My vague impression is that Bash started as an attempt to combine
csh and sh, but it's not clear to me how soon people noticed the
infeasibility and pivoted to a sh-based model.  Or maybe that's not
at all how it happened.

The Bash README says that

    Bash is the GNU Project's Bourne Again SHell, a complete
    implementation of the POSIX shell spec, but also with interactive
    command line editing, job control on architectures that support
    it, csh-like features such as history substitution and brace
    expansion, and a slew of other features.

My understanding is that it was always intended to be POSIX-based
(also implied by the name "Bourne Again SHell", where the POSIX
shell spec is based on the Bourne shell), with some additional
features copied from csh and elsewhere.
