Erase data (applied to hard drives), usually used when deleting files containing sensitive data. More reliable than the delete command, the information cannot be recovered.
Rub [target ...] [/ p] [/ f] [/ s] [/ q] [/ a [[:] attributes]] [/ m [:] scheme] [/ d]
Parameters: (No matter where you, lethar cases) do not parameter or? Display User's Description Target path, you can specify more than one file or folder to the target in the current directory to save the path to match the file name to select multiple File (wildcard mismatch folder) / s looks for subdirectories and all the same names or matching files / P in all subdirectories, prompts to confirm before operating each target, the default does not perform the prompt / q does not match the wildcard The operation requirements under the folder prompts that the default is always prompted (/ P / Q) / a Filter attributes R read-only file S system file h hidden according to the target properties (folder and wildcard matching files) File A archive file - prefix, indicating "No" / f to force the target with read-only properties, the default read-only file is ignored (when / A: r, / f will be automatically opened) / m Erase file mode, Scheme is homoked by the following character: SCHEME 0 overrides "0" override once REASE RETER 1 Random number over 1 1 Per Sense "1" overwrites once X Deletion (Please place it in the last) Other characters ignore, optional Default scheme = "0" US National Computer Security Center recommended, using "10RRR" in an important occasion, the number of additional erasing times may be more insurance. After / d, delete the target, the default is not deleted (the operation file is not completed) (the folder that is not cleared is not deleted) (However, the target of other completion operations will be deleted)
Example: C: /> RUB Password.log / M: 10R 'Overlay file mode is once 1, once 0, random C: /> RUB C: / DATA / / D / F' Erase and delete folder DATA All, and delete the folder C: /> RUB C:. / Data / * pwd / S 'erase C: / Data / folder including all subdirectories under the file suffix .pwd _______________________________________________________________________________
