GCLOUD_TOPIC_FORMATS(1)

NAME

gcloud topic formats - resource formats supplementary help

DESCRIPTION
Most gcloud commands return a list of resources on success. By default they are pretty-printed on the standard output. The --format=NAME[ATTRIBUTES](PROJECTION) flag changes the default output: NAME
    The format name.
ATTRIBUTES
    Format specific attributes. Resource formats are described in detail below.
PROJECTION
    A list of resource keys that selects the data listed. For details run $ gcloud topic projections.
resource keys
    Keys are names for resource resource items. For details run $ gcloud topic resource-keys. Most gcloud list commands have a --filter=EXPRESSION flag that selects resources to be listed. For details run $ gcloud topic filters.

Formats
A format expression has 3 parts: NAME
    name
ATTRIBUTES
    [ [no-]attribute-name[=value] [, ... ] ]
PROJECTION
    ( resource-key [, ...] ) NAME is required, ATTRIBUTES are optional, and PROJECTIONS may be required for some formats. Unknown attribute names are silently ignored.
Each gcloud list command has a default format expression. The --format flag can alter or replace the default. For example,
    --format='[box]'
adds box decorations to a default table, and
    --format=json
lists the resource in json format. The formats and format specific attributes are: csv
    Comma Separated Values (http://www.ietf.org/rfc/rfc4180.txt) with no keys. This format requires a projection to define the values to be printed. The format attributes are: no-heading
        Disables the initial key name heading record.
default
    An alias for the yaml format.
flattened
    A flattened tree. Each output line contains one key:value pair. The format attributes are: no-pad
        bool, Print only one space after ':'. The default adjusts the space to align the values into the same output column. Use no-pad for comparing resource outputs.
json
    JSON (http://www.json.org), JavaScript Object Notation.
list
    An ordered list of items.
multi
    Each projection key must have a subformat defined by the :format=FORMAT-STRING attribute. For example, --format='multi(data:format=json, info:format="table[box](a, b, c)")' formats the data field as JSON and the info field as a boxed table.
none
    Disables formatted output and consumes the resources.
table
    Aligned left-adjusted columns with optional title, column headings and sorting. This format requires a projection to define the table columns. The default column headings are the disambiguated right hand components of the column keys in ANGRY_SNAKE_CASE. For example, the projection keys (first.name, last.name) produce the default column heading ('NAME', 'LAST_NAME'). If --page-size=N is specified then output is grouped into tables with at most N rows. Headings, alignment and sorting are done per-page. The title, if any, is printed before the first table. The format attributes are: box
        Prints a box around the entire table and each cell, including the title if any.
    format=FORMAT-STRING
        Prints the key data indented by 4 spaces using FORMAT-STRING which can reference any of the supported formats.
    no-heading
        Disables the column headings.
    optional
        Does not display the column if it is empty.
    pad=N
        Sets the column horizontal pad to N spaces. The default is 1 for box, 2 otherwise.
    title=TITLE
        Prints a centered TITLE at the top of the table, within the table box if box is enabled.
text
    An alias for the flattened format.
value
    CSV with no heading and <TAB> separator instead of <COMMA>. Used to retrieve individual resource values. This format requires a projection to define the value(s) to be printed. The format attributes are: quote
        "..." quote values that contain <TAB>, <NEWLINE> or ".
yaml
    YAML (http://www.yaml.org), YAML ain't markup language.
All formats have these attributes: disable
    Disables formatted output and does not consume the resources.
private
    Disables log file output. Use this for sensitive resource data that should not be displayed in log files. Explicit command line IO redirection overrides this attribute.

EXAMPLES
List a table of compute instance resources sorted by name with box decorations and title Instances:
    $ gcloud compute instances list \
        --format='table[box,title=Instances](name:sort=1,
     zone:title=zone, status)'
List the disk interfaces for all compute instances as a compact comma separated list:
    $ gcloud compute instances list \
        --format='value(disks[].interface.list())'
List the URIs for all compute instances:
    $ gcloud compute instances list --format='value(uri())'
List the project authenticated user email address:
    $ gcloud info --format='value(config.account)'
