datalad get - get any dataset content (files/directories/subdatasets).


datalad get [-h] [-s LABEL] [-d PATH] [-r] [--recursion-limit LEVELS] [-n] [-D DESCRIPTION] [--reckless] [-J NJOBS] [-v] [PATH [PATH ...]]


This command only operates on dataset content. To obtain a new independent dataset from some source use the INSTALL command.

By default this command operates recursively within a dataset, but not across potential subdatasets, i.e. if a directory is provided, all files in the directory are obtained. Recursion into subdatasets is supported too. If enabled, relevant subdatasets are detected and installed in order to fulfill a request.

Known data locations for each requested file are evaluated and data are obtained from some available location (according to git-annex configuration and possibly assigned remote priorities), unless a specific source is specified.

Power-user info: This command uses git annex get to fulfill file handles.


path/name of the requested dataset component. The component must already be known to a dataset. To add new components to a dataset use the ADD command. Constraints: value must be a string [Default: None]

-h, --help, --help-np
show this help message. --help-np forcefully disables the use of a pager for displaying the help message
-s LABEL, --source LABEL
label of the data source to be used to fulfill requests. This can be the name of a dataset sibling or another known source. Constraints: value must be a string [Default: None]
-d PATH, --dataset PATH
specify the dataset to perform the add operation on, in which case PATH arguments are interpreted as being relative to this dataset. If no dataset is given, an attempt is made to identify a dataset for each input PATH. Constraints: Value must be a Dataset or a valid identifier of a Dataset (e.g. a path) [Default: None]
-r, --recursive
if set, recurse into potential subdataset. [Default: False]
--recursion-limit LEVELS
limit recursion into subdataset to the given number of levels. Alternatively, 'existing' will limit recursion to subdatasets that already existed on the filesystem at the start of processing, and prevent new subdatasets from being obtained recursively. Constraints: value must be convertible to type 'int', or value must be one of ('existing',) [Default: None]
-n, --no-data
whether to obtain data for all file handles. If disabled, GET operations are limited to dataset handles. This option prevents data for file handles from being obtained. [Default: True]
short description to use for a dataset location. Its primary purpose is to help humans to identify a dataset copy (e.g., "mike's dataset on lab server"). Note that when a dataset is published, this information becomes available on the remote side. Constraints: value must be a string [Default: None]
Set up the dataset to be able to obtain content in the cheapest/fastest possible way, even if this poses a potential risk the data integrity (e.g. hardlink files from a local clone of the dataset). Use with care, and limit to "read-only" use cases. With this flag the installed dataset will be marked as untrusted. [Default: False]
-J NJOBS, --jobs NJOBS
how many parallel jobs (where possible) to use. Constraints: value must be convertible to type 'int', or value must be one of ('auto',) [Default: 'auto']
-v, --verbose
print out more detailed information while executing a command. [Default: False]
