usage: ru [-c[t]] [-l <levels> | -n | -v] [-q] <absolute path>
usage: ru [-c[t]] [-l <levels> | -n | -v] [-q] -h <hive file> [relative path]
| Parameter | Description |
|---|---|
| -c | Print output as CSV. Specify -ct for tab delimiting. |
| -h | Load the specified hive file, perform the size calculation, then unload it and compress it. |
| -l | Specify subkey depth of information (default is one level). |
| -n | Do not recurse. |
| -q | Quiet (no banner). |
| -v | Show size of all subkeys. |
