    The “-“ is often not necessary. I use it as a guide to see how long the person running tar has been using it.

    Example:

    tar -xf file.tar == tar xf file.tar

      They are functionally flags though and uniletter flags should be preceded by a ‘-’, so I would still prefer to have the ‘-’ written, because it conforms with the standard.
