@bontchev@infosec.exchange Plenty of .tgz and .txz files around in the Unix world! (I didn’t mention file endings like .tar.gz because the tag “tar” is there in plain sight.) As an example, the oldest Linux distro that’s still going publishes its packages with .txz at the end, and as far as I know has always used .t_z (the middle letter has varied as preferred compression formats have come and gone). It may well be that this comes from the early days of floppy-based distros with files written in old-school DOS format (only one dot possible) but that’s moot today… I accept that ‘tar’ used as the name of the program denotes “tape archiver,” because that is its purpose, but as the usual tag added at the end of any filename it generates or consumes, I am happy enough with the explanatory text “tape archive,” because that is what is is. (I know a tar *file* is not exactly a *tape*, but we still “dial” phones and “film” videos, so I am happy with the word “tape” in a sort of metaphorico-historical way.) So I think I’ll stick with tar —> tape archive. Think of ‘archive’ as a verb when running the binary and as a noun when referring to its output.
