I’ll use whatever’s available. The first thing to do is look for
options to customize the output, to reduce or even eliminate the need
to pull bits out with regexes or other complex parsing.

    root@theon:~ # ip addr --oneline

    root@theon:~ # ip addr show --oneline
    Device "--oneline" does not exist.
    root@theon:~ # ip --oneline addr show
