In general, at least with most *nix shells, ? is a poor choice for an
option. It is like using * in an option. If a file or directory name
in your current directory exists, then the ? gets replaced by it (or
all of them if more than one).

I've noticed this as well with -cpu ? and the like, and use -cpu '?'
when that happens, as the ' ' suppresses the substitution.

On a similar vein, I'm seen apps use /? on Linux for help, and that is
sometimes thwarted as well.
