Note

The butler subcommands documented here are only those defined in the daf_butler package itself; downstream packages can implement additional subcommands via the plugin system described at The Butler Command. The best way to get a complete list of subcommands is to use butler --help.

butler¶

butler [OPTIONS] COMMAND [ARGS]...

Options

--log-level <LEVEL|COMPONENT=LEVEL>¶: The logging level. Without an explicit logger name, will only affect the default root loggers (lsst). To modify the root logger use ‘.=LEVEL’. Supported levels are [CRITICAL|ERROR|WARNING|INFO|VERBOSE|DEBUG|TRACE]

--long-log¶: Make log messages appear in long format.

--log-file <log_file>¶: File(s) to write log messages. If the path ends with ‘.json’ then JSON log records will be written, else formatted text log records will be written. This file can exist and records will be appended.

--log-tty, --no-log-tty¶: Log to terminal (default). If false logging to terminal is disabled.

--log-label <log_label>¶: Keyword=value pairs to add to MDC of log records.

--progress, --no-progress¶: Show a progress bar for slow operations when possible.

register-skymap¶

Make a SkyMap and add it to a repository.

REPO is the URI or path to the gen3 repository. Will be created if it does not already exist

butler register-skymap [OPTIONS] REPO

Options

-c, --config <TEXT=TEXT>¶: Config override, as a key-value pair.

-C, --config-file <config_file>¶: Path to a config file overrides file.

-@, --options-file <options_file>¶: URI to YAML file containing overrides of command line options. The YAML should be organized as a hierarchy with subcommand names at the top level options for that subcommand below.

Arguments

REPO¶: Required argument

See ‘butler –help’ for more options.

remove-collections¶

Remove one or more non-RUN collections.

COLLECTION is a glob-style expression that identifies the collection(s) to remove.

This command can be used to remove only non-RUN collections. If RUN collections are found when searching for collections (and the –no-confirm flag is not used), then they will be shown in a separate table during confirmation, but they will not be removed.

Use the remove-runs subcommand to remove RUN collections.

butler remove-collections [OPTIONS] REPO COLLECTION

Options

--confirm, --no-confirm¶: Print expected action and a confirmation prompt before executing. Default is –confirm.

-@, --options-file <options_file>¶: URI to YAML file containing overrides of command line options. The YAML should be organized as a hierarchy with subcommand names at the top level options for that subcommand below.

Arguments

REPO¶: Required argument

COLLECTION¶: Required argument

See ‘butler –help’ for more options.

remove-dataset-type¶

Remove a dataset type definition from a repository.

REPO is the URI or path to an existing data repository root or configuration file.

butler remove-dataset-type [OPTIONS] REPO DATASET_TYPE_NAME

Arguments

REPO¶: Required argument

DATASET_TYPE_NAME¶: Required argument

See ‘butler –help’ for more options.

remove-runs¶

Remove one or more RUN collections.

COLLECTION is a glob-style expression that identifies the RUN collection(s) to remove.

This command can be used to remove RUN collections and the datasets within them.

butler remove-runs [OPTIONS] REPO COLLECTION

Options

--confirm, --no-confirm¶: Print expected action and a confirmation prompt before executing. Default is –confirm.

-@, --options-file <options_file>¶: URI to YAML file containing overrides of command line options. The YAML should be organized as a hierarchy with subcommand names at the top level options for that subcommand below.

Arguments

REPO¶: Required argument

COLLECTION¶: Required argument

See ‘butler –help’ for more options.

retrieve-artifacts¶

Retrieve file artifacts associated with datasets in a repository.

REPO is the URI or path to an existing data repository root or configuration file.

Destination URI of folder to receive file artifacts.

butler retrieve-artifacts [OPTIONS] REPO DESTINATION

Options

-d, --dataset-type <dataset_type>¶: One or more glob-style expressions that fully or partially identify the dataset type names to be queried.

--collections <collections>¶: One or more expressions that fully or partially identify the collections to search for datasets. If not provided all datasets are returned.

--where <where>¶: A string expression similar to a SQL WHERE clause. May involve any column of a dimension table or a dimension name as a shortcut for the primary key column of a dimension table.

--find-first¶: For each result data ID, only yield one DatasetRef of each DatasetType, from the first collection in which a dataset of that dataset type appears (according to the order of ‘collections’ passed in). If used, ‘collections’ must specify at least one expression and must not contain wildcards.

-t, --transfer <transfer>¶

The external data transfer mode.

Options:	auto \| link \| symlink \| hardlink \| copy \| move \| relsymlink \| direct

-v, --verbose¶: Report destination location of all transferred artifacts.

--preserve-path, --no-preserve-path¶: Preserve the datastore path to the artifact at the destination.

--clobber, --no-clobber¶: If clobber, overwrite files if they exist locally.

-@, --options-file <options_file>¶: URI to YAML file containing overrides of command line options. The YAML should be organized as a hierarchy with subcommand names at the top level options for that subcommand below.

Arguments

REPO¶: Required argument

DESTINATION¶: Required argument

See ‘butler –help’ for more options.

transfer-datasets¶

Transfer datasets from a source butler to a destination butler.

SOURCE is a URI to the Butler repository containing the RUN dataset.

DEST is a URI to the Butler repository that will receive copies of the datasets.

butler transfer-datasets [OPTIONS] SOURCE DEST

Options

-d, --dataset-type <dataset_type>¶: One or more glob-style expressions that fully or partially identify the dataset type names to be queried.

--collections <collections>¶: One or more expressions that fully or partially identify the collections to search for datasets. If not provided all datasets are returned.

--where <where>¶: A string expression similar to a SQL WHERE clause. May involve any column of a dimension table or a dimension name as a shortcut for the primary key column of a dimension table.

--find-first¶: For each result data ID, only yield one DatasetRef of each DatasetType, from the first collection in which a dataset of that dataset type appears (according to the order of ‘collections’ passed in). If used, ‘collections’ must specify at least one expression and must not contain wildcards.

-t, --transfer <transfer>¶

The external data transfer mode.

Options:	auto \| link \| symlink \| hardlink \| copy \| move \| relsymlink \| direct

--register-dataset-types¶: Register DatasetTypes that do not already exist in the Registry.

-@, --options-file <options_file>¶: URI to YAML file containing overrides of command line options. The YAML should be organized as a hierarchy with subcommand names at the top level options for that subcommand below.

Arguments

SOURCE¶: Required argument

DEST¶: Required argument

See ‘butler –help’ for more options.
