.SH NAME
\fBdatalad get\fR \- get any dataset content (files/directories/subdatasets).
.SH SYNOPSIS

.HP
\fBdatalad get\fR [-h] [-s\~LABEL] [-d\~PATH] [-r] [--recursion-limit\~LEVELS] [-n] [-D\~DESCRIPTION] [--reckless] [-J\~NJOBS] [-v] [PATH [PATH ...]]

.SH DESCRIPTION

This command only operates on dataset content. To obtain a new independent
dataset from some source use the INSTALL command.
.PP
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.
.PP
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.
.PP
.TP
NOTE
Power\-user info: This command uses git annex get to fulfill
file handles.
.SH OPTIONS
.TP
PATH
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]

.TP
\fB-h\fR, \fB--help\fR, \fB--help-np\fR
show this help message. --help-np forcefully disables the use of a pager for displaying the help message
.TP
\fB-s\fR LABEL, \fB--source\fR 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]
.TP
\fB-d\fR PATH, \fB--dataset\fR 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]
.TP
\fB-r\fR, \fB--recursive\fR
if set, recurse into potential subdataset. [Default: False]
.TP
\fB--recursion-limit\fR 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]
.TP
\fB-n\fR, \fB--no-data\fR
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]
.TP
\fB-D\fR \fI\s-1DESCRIPTION\s0\fR, \fB--description\fR \fI\s-1DESCRIPTION\s0\fR
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]
.TP
\fB--reckless\fR
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]
.TP
\fB-J\fR NJOBS, \fB--jobs\fR 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']
.TP
\fB-v\fR, \fB--verbose\fR
print out more detailed information while executing a command. [Default: False]
