        tar -xf is not really special combining short options isn’t uncommon.

        Where tar is nonstandard is that you can leave out the -, tar xf is actually how POSIX specifies it. And we’ve kinda come full circle on that one with many modern utilities using a command syntax, you can read tar xf as “tar extract file” just as you can read git pull as, well, “git pull”.

        If you want to see a standard command with truly non-standard syntax have a look at dd.

      Many do, but it’s not guaranteed, it just depends on the individual command (program). Usually you can use the --help option to see all the options, so for instance tar --help.
