rm cannot delete files starting with "--"
提问by frazras
I have a script that creates files, and sometimes they end up having two dashes at the beginning. Is there any way to delete them? mvdoesn't work either.

更新：以下是man rm对此的看法：
To remove a file whose name starts with a '-', for example '-foo', use
one of these commands:
rm -- -foo
rm ./-foo

Use --to separate options from parameters.
使用--从参数不同的选项。
$ rm -- --1355509766.jpg
This works with other commands too. For example:
这也适用于其他命令。例如：
$ touch -- -v # create a file called -v
$ grep foo -- -v # grep for "foo" in file called -v

Try file name with path:
尝试带路径的文件名：
$ rm ./--file.name
Example:
例子：
$ echo dgag > --test.txt
$ ls
--test.txt
$ rm ./--test.txt
$ ls
