Options

Supported options are listed below. Most options have both single-letter and full-name forms. Multiple single-letter options that do not take an argument can be combined. For example, –fv is the equivalent of –f –v. A full-name option can be abbreviated to a unique prefix of its name.

–a, –-attribute type

Display the contents of a particular attribute type. By default, the unnamed $DATA attribute will be shown. The attribute can be specified by a number in decimal or hexadecimal, or by name.

Hex     Decimal Name
0x10    16      "$STANDARD_INFORMATION"
0x20    32      "$ATTRIBUTE_LIST"
0x30    48      "$FILE_NAME"
0x40    64      "$OBJECT_ID"
0x50    80      "$SECURITY_DESCRIPTOR"
0x60    96      "$VOLUME_NAME"
0x70    112     "$VOLUME_INFORMATION"
0x80    128     "$DATA"
0x90    144     "$INDEX_ROOT"
0xA0    160     "$INDEX_ALLOCATION"
0xB0    176     "$BITMAP"
0xC0    192     "$REPARSE_POINT"
0xD0    208     "$EA_INFORMATION"
0xE0    224     "$EA"
0xF0    240     "$PROPERTY_SET"
0x100   256     "$LOGGED_UTILITY_STREAM"

The attribute names can be specified without the leading dollar sign ($) symbol. If you use the $ symbol, you must quote the name to prevent the shell from interpreting the name.

–f, –-force

Overrides some sensible defaults, such as not using a mounted volume. Use this option with caution.

–h, –-help

Show a list of options with a brief description of each.

–i, –-inode num

Specify a file by its inode number instead of its name.

–n, –-attribute-name name

Display the attribute identified by name.

–q, –-quiet

Suppress some debug, warning, and error messages.

–V, –-version

Show the version number, copyright, and license information.

–v, –-verbose

Display more debug, warning, and error messages.
