Early versions of MS-DOS syntax

ERASE [drive:][path]file name [/P]

erase 示例
erase c:\windows\*.tmp
删除所有以TMP扩展名结尾的文件(即临时文件)。
erase c:\windows\*.tmp
Delete any files that end with the TMP extension (i.e. temporary file).
运行此命令时，您不会收到确认提示。一旦执行，所有文件都将被删除，除非它们具有只读属性并且未使用/F开关。
You will not receive a confirmation prompt when running this command. Once executed, all files will be deleted unless they have a read-only attribute and the /F switch is not being used.
