Renaming a folder...

I renamed a folder to $574dor&*rnf. I could not access this folder now nor
do I can rename it. It has become inaccessible. How do I restore it.

I get following error while moving it.

[1] 2607
mv: missing file argument
Try `mv --help' for more information.
bash: $574dor&*rnf: command not found
[1]+  Exit 1                  mv -i $574dor


Thank you,

Tina..
