The usual solution for that problem is to use "--" to indicate that
the words following are file names and not options. For example, if
you execute
grep string *
in a directory containing some file names beginning with "-", those
names will be treated as options. If instead you execute
grep string -- *
then all file names will be treated as file names.
An example of this is given near the bottom of recent versions of
the grep(1) man page, under EXAMPLES.
