DESCRIPTION
DataLad provides a unified data distribution with the convenience of git-annex repositories as a backend.
DataLad command line tools allow to manipulate (obtain, create, update, publish, etc.) datasets and their
collections.
Commands for dataset operations
create Create a new dataset from scratch
install
Install a dataset from a (remote) source
get Get any dataset content (files/directories/subdatasets)
add Add files/directories to an existing dataset
publish
Publish a dataset to a known sibling
uninstall
Uninstall subdatasets
drop Drop file content from datasets
remove Remove components from datasets
update Update a dataset from a sibling
create-sibling
Create a dataset sibling on a UNIX-like SSH-accessible machine
create-sibling-github
Create dataset sibling on Github
unlock Unlock file(s) of a dataset
save Save the current state of a dataset
plugin Generic plugin interface
Commands for meta data handling
search Search within available in datasets' meta data
metadata
Metadata manipulation for files and whole datasets
aggregate-metadata
Aggregate meta data of a dataset for later query
Miscellaneous commands
test Run internal DataLad (unit)tests
crawl Crawl online resource to create or update a dataset
crawl-init
Initialize crawling configuration
ls List summary information about URLs and dataset(s)
clean Clean up after DataLad (possible temporary files etc.)
add-archive-content
Add content of an archive under git annex control
download-url
Download content
run Run an arbitrary command and record its impact on a dataset
rerun Re-execute previous `datalad run` commands
Plumbing commands
annotate-paths
Analyze and act upon input paths
clone Obtain a dataset copy from a URL or local source (path)
create-test-dataset
Create test (meta-)dataset
diff Report changes of dataset components
siblings
Manage sibling configuration
sshrun Run command on remote machines via SSH
subdatasets
Report subdatasets and their properties
General information
Detailed usage information for individual commands is available via command-specific --help, i.e.: datal‐
ad <command> --help
OPTIONS
{create, install, get, add, publish, uninstall, drop, remove, update, create-sibling, create-sibling-
github, unlock, save, plugin, search, metadata, aggregate-metadata, test, crawl, crawl-init, ls, clean,
add-archive-content, download-url, run, rerun, annotate-paths, clone, create-test-dataset, diff, sib‐
lings, sshrun, subdatasets}
-h, --help, --help-np
show this help message. --help-np forcefully disables the use of a pager for displaying the help
message
-l LEVEL, --log-level LEVEL
set logging verbosity level. Choose among critical, error, warning, info, debug. Also you can
specify an integer <10 to provide even more debugging information
--pbs-runner {condor}
execute command by scheduling it via available PBS. For settings, config file will be consulted
-C PATH
run as if datalad was started in <path> instead of the current working directory. When multiple -C
options are given, each subsequent non-absolute -C <path> is interpreted relative to the preceding
-C <path>. This option affects the interpretations of the path names in that they are made rela‐
tive to the working directory caused by the -C option
--version
show the program's version and license information
--dbg enter Python debugger when uncaught exception happens
--idbg enter IPython debugger when uncaught exception happens
-c KEY=VALUE
configuration variable setting. Overrides any configuration read from a file, but is potentially
overridden itself by configuration variables in the process environment.
--output-format {default, json, json_pp, tailored,'<template>'
select format for returned command results. 'default' give one line per result reporting action,
status, path and an optional message; 'json' renders a JSON object with all properties for each
result (one per line); 'json_pp' pretty-prints JSON spanning multiple lines; 'tailored' enables a
command-specific rendering style that is typically tailored to human consumption (no result output
otherwise), '<template>' reports any value(s) of any result properties in any format indicated by
the template (e.g. '{path}', compare with JSON output for all key-value choices).
--report-status {success, failure, ok, notneeded, impossible, error}
constrain command result report to records matching the given status. 'success' is a synonym for
'ok' OR 'notneeded', 'failure' stands for 'impossible' OR 'error'.
--report-type {dataset, file}
constrain command result report to records matching the given type. Can be given more than once to
match multiple types.
--on-failure {ignore, continue, stop}
when an operation fails: 'ignore' and continue with remaining operations, the error is logged but
does not lead to a non-zero exit code of the command; 'continue' works like 'ignore', but an error
causes a non-zero exit code; 'stop' halts on first failure and yields non-zero exit code. A fail‐
ure is any result with status 'impossible' or 'error'.
--run-before PLUGINSPEC [PLUGINSPEC ...]
DataLad plugin to run after the command. PLUGINSPEC is a list comprised of a plugin name plus op‐
tional `key=value` pairs with arguments for the plugin call (see `plugin` command documentation
for details). This option can be given more than once to run multiple plugins in the order in
which they were given. For running plugins that require a --dataset argument it is important to
provide the respective dataset as the --dataset argument of the main command, if it is not in the
list of plugin arguments.
--run-after PLUGINSPEC [PLUGINSPEC ...]
Like --run-before, but plugins are executed after the main command has finished.
--cmd syntactical helper that can be used to end the list of global command line options before the sub‐
command label. Options like --run-before can take an arbitray number of arguments and may require
to be followed by a single --cmd in order to enable identification of the subcommand.
