How to delete a folder starting with a specific character?

Question

cmd/bat

I have a certain folder in which there is a set of folders, some of them are named number_number and number_-number, others are named -number_number and -number_-number. Folders contain files that must be deleted along with them. The folders of the second group (the name starts with -) are subject to deletion. How to do it?
PS: I have windows.

Answer 1

for /d %D in (-*) do rd /s /q "%D"
(when used in a batch file %D, replace with %%D)
- see help for FOR and RD commands:

for /?
rd /?
