List sizes of the files and directories in a specific directory.

Synopsis

du [-h] [-s] <directories>
Syntax legend
Syntax conventions Description

Italic, bold, or < >

Syntax diagrams and code samples use one or more of these styles to mark placeholders for variable values. Replace placeholders with a valid option or your own user-defined value.

In CQL statements, angle brackets are required to enclose data types in a set, list, map, or tuple. Separate the data types with a comma. For example: <datatype2

In Search CQL statements, angle brackets are used to identify the entity and literal value to overwrite the XML element in the schema and solrconfig files, such as @<xml_entity>='<xml_entity_type>'.

[ ]

Square brackets surround optional command arguments. Do not type the square brackets.

( )

Parentheses identify a group to choose from. Do not type the parentheses.

|

A pipe separates alternative elements. Type any one of the elements. Do not type the pipe.

...

Indicates that you can repeat the syntax element as often as required.

'

Single quotation marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case. + For Search CQL only: Single quotation marks surround an entire XML schema declaration, such as '<<schema> ... </schema>>'

{ }

Map collection. Curly braces enclose maps ({ <key_datatype>:<value_datatype> }) or key value pairs ({ <key>:<value> }). A colon separates the key and the value.

;

Ends a CQL statement.

--

Separate command line options from command arguments with two hyphens. This syntax is useful when arguments might be mistaken for command line options.

Options

If an option has a short and long form, both forms are given, separated by a comma.

-h, --human-readable

Display human-readable sizes. For example, 1.25k, 234M, or 2G.

-s, --summarized

Display only the total size of all files and directories.

directories

The directories to search to calculate the space usage.

Examples

Get disk usage from the root of the DSEFS file system:

dse fs "du"
464827  example1
     0  tmp/hive
     0  tmp
464827  .

Get the disk usage from the example1 directory in human readable form:

dse fs "du -h example1"
454K  example1

Get the total disk usage in human readable form of all files in DSEFS:

dse fs "du -h -s"
454K  .
