filesystem.listdir

Get the contents of a directory.

The select option may be used to optimize listdir performance. Metadata-related fields that are not selected will not be retrieved from the filesystem.

For example {“select”: [“path”, “type”]} will avoid querying an xattr list and ZFS attributes for files in a directory.

NOTE: an empty list for select (default) is treated as requesting all information.

Each entry of the list consists of: name(str): name of the file path(str): absolute path of the entry realpath(str): absolute real path of the entry (if SYMLINK) type(str): DIRECTORY | FILE | SYMLINK | OTHER size(int): size of the entry allocation_size(int): on-disk size of entry mode(int): file mode/permission uid(int): user id of entry owner gid(int): group id of entry owner acl(bool): extended ACL is present on file is_mountpoint(bool): path is a mountpoint is_ctldir(bool): path is within special .zfs directory attributes(list): list of statx file attributes that apply to the file. See statx(2) manpage for more details. xattrs(list): list of extended attribute names. zfs_attrs(list): list of ZFS file attributes on file

Parameter 3: query_options

query_options

Type: object
Default:
{ "relationships": true, "extend": null, "extend_fk": [], "extend_context": null, "prefix": null, "extra": {}, "order_by": [], "select": [], "count": false, "get": false, "offset": 0, "limit": 0, "force_sql_filters": false }

Query options customize the results returned by a query method. More complete documentation with examples
are covered in the "Query methods" section of the TrueNAS API documentation.

Prefix

Default: null

Type: string
Type: null

Extra

Type: object Default: {}

Extra options are defined on a per-endpoint basis and are described in the documentation for the associated
query method.

Order By

Type: array of string Default: []

An array of field names describing the manner in which query results should be ordered. The field names may
also have one of more of the following special prefixes: - (reverse sort direction), nulls_first: (place
any null values at the head of the results list), nulls_last: (place any null values at the tail of the
results list).

No Additional Items
Each item of this array must be:
Type: string

Example:

[
    "size",
    "-devname",
    "nulls_first:-expiretime"
]

Select

Type: array Default: []

An array of field names specifying the exact fields to include in the query return. The dot character .
may be used to explicitly select only subkeys of the query result.

No Additional Items

No Additional Items
Each item of this array must be:
Type: object

Example:

[
    "username",
    "Authentication.status"
]

Count

Type: boolean Default: false

Return a numeric value representing the number of items that match the specified query-filters.

Get

Type: boolean Default: false

Return the JSON object of the first result matching the specified query-filters. The query fails
if there specified query-filters return no results.

Offset

Type: integer Default: 0

This specifies the beginning offset of the results array. When combined with the limit query-option
it may be used to implement pagination of large results arrays. WARNING: some query methods provide
volatile results and the onus is on the developer to understand whether pagination is appropriate
for a particular query API method.

Limit

Type: integer Default: 0

This specifies the maximum number of results matching the specified query-filters to return. When
combined wtih the offset query-option it may be used to implement pagination of large results arrays.
WARNING: some query methods provide volatile results and the onus is on the developer to understand whether
pagination is appropriate for a particular query API method.
