Install latest package without prompts on OpenBSD 7.0

[Jeffrey Walton]

Hi Everyone,

I am working on OpenBSD 7.0, x86_64. I'm trying to script an install
of developer tools I use, like GCC and Git. When I attempt to install
GCC I am prompted:

    $ sudo pkg_add gcc g++
    quirks-4.54 signed on 2022-01-09T19:08:35Z
    Ambiguous: choose package for gcc
    a    0: <None>
        1: gcc-8.4.0p9
        2: gcc-11.2.0p0

I've looked over the man page at https://man.openbsd.org/pkg_add, but
I don't see an option to tell pkg_add to install the latest version of
the package.

How do I tell pkg_add to install the latest version without prompting me?

Thanks in advance.
