mv: invalid option — '0'

Question

How can I rename files with "-" in front of the filename, for example: "-0001.jpg"

Everyime I try to run:

for i in *; do mv "$i" "${i//-/}"; done

or:

for i in *; do mv "$i" "${i#*-}"; done

I got this error:

mv: invalid option -- '0'
Try `mv --help' for more information.

Thanks for any light!
