if I create a file that first character is "-" I cannot remove or move file. (file name is same parameter)
But I can remove or move with python script

```shell
sulin@SulinOS:test :)  > echo aa > -f
sulin@SulinOS:test :)  > ls
-f
sulin@SulinOS:test :)  > rm -f -f
sulin@SulinOS:test :)  > ls
-f
sulin@SulinOS:test :)  > python3

sulin@SulinOS:test :)  > ls

```
