> address@hidden:/home/test$ md5sum --check '-=Bob Marley=-.md5'
> md5sum: invalid option -- '='

Not a bug.  And not unique to md5sum either; POSIX requires that most apps
behave this way (only a few exceptions for legacy programs like echo).

Try either of these, to see the difference.  Basically, you need to tell
your program that '-=Bob Marley=-.md5' is not an option, but an argument,
either by avoiding a leading-, or by using the explicit end-of-options option.

md5sum --check -- '-=Bob Marley=-.md5'
md5sum --check './-=Bob Marley=-.md5'

- --
Don't work too hard, make some time for fun as well!
