looks like a bug in md5sum, sha1sum,sha256sum..

[cor]

This acts like a bug:

address@hidden:~$
address@hidden:~$ cd /home/test
address@hidden:/home/test$ md5sum --check '-=Bob Marley=-.md5'
md5sum: invalid option -- '='
Try `md5sum --help' for more information.
address@hidden:/home/test$

for now..
