    Can anybody tell me how I can look at the official change history of
    linux commands?

    For example, the test(1) command used to have a regular-expression
    parser built in.  No longer, and more surprising, there's no discussion
    of its disappearance on the internet; that I can find, at any rate.

    I'd to know when it disappeared and what discussions, by whom, preceded
    that.



    Sorry, I'm thinking of the expr(1) command.

    The man pages (and source code) of old versions of UNIX can be found at

    https://minnie.tuhs.org/cgi-bin/utree.pl

    e.g. ("man 1 expr" from Jan 1992) https://minnie.tuhs.org/cgi-bin/utree.pl?file=V10/man/man1/expr.1

    For more human readable output
    $ cd tmp
    $ cat > oldman.1
    <copy and paste>
    $ man ./oldman.1
