Using double -- for long named flags is a GNU-ism. Java came from Sun and so prefers the single dashes.

  But "-help" is just "-h -e -l -p" ...

    Which is also a gnuism
    • oneeyedpigeon 4y ago
      That's my point - "-help" violates the gnu standard.
      • lou1306 4y ago
        That's his point, Sun has nothing to do with Gnu so they are not bound to their "standards".
      • arccy 4y ago
        the point was that that gnu is not a universal standard

      “-help” being equivalent to “-h -e -l -p” is not a GNUism. It’s described by POSIX. If a utility takes the options “-a” and “-o something” and uses POSIX getopt(), then these are all equivalent: cmd -ao arg path path cmd -a -o arg path path cmd -o arg -a path path cmd -a -o arg -- path path cmd -a -oarg path path cmd -aoarg path path
