The Brown Dog Command Line Interface (BD-CLI) provides users with an easy to use interface to Brown Dog services. It talks to various components of Brown Dog through its API. It can be used to do operations like file conversions and extractions. Please see the README for current instructions.
You can install BD-CLI from the PyPi repository by following these steps:
pip install bdcli
This will install bdcli and all the dependent packages and you should see a new application bd from your terminal.
Extraction refers to the process of deriving additional useful information from the contents of one or more files/datasets that helps a user or application in determining what's in the file/dataset or collection of files/datasets. For example, using machine learning to find an object in an image. For example:
Here we are using the development instance of Brown Dog by passing in the API URL using -b option. This is an optional flag and by default BD-CLI uses the production API instance at https://bd-api.ncsa.illinois.edu. The results of the extraction are by default placed ina JSON file, in this case ncsa.json:
examples $ cat ncsa.json | jq .

Optionally you can use the -v flag to get a more verbose output, including the content of the output file ncsa.json. You can also get a list of available extractors that will process a given input file:
Conversions refer to the process of transforming files/datasets from one format to another. This is especially useful when you do not have a specific software required to open your input file. For example, the screenshot below shows a situation when software needed to open a PGM image file is not available:
To get around this the file can be converted to another format for which required software is available (say JPEG). With the Brown Dog DTS you can do this via a remote service without having to worry about have such utilities locally installed. For example, using the conversion command below:
Now, you can open the file to view the converted file:
Similar to extraction, you can get a list of output formats to which a given input file can be converted:
This list will grow over time as new conversion capabilities get added to the DTS.
Using this feature you can combine two or more transformations in a single command. For example, converting a PGM file to PNG and then doing an extraction:
which generates:
examples $ cat balloons.json | jq .

Like with most command line tools BD-CLI supports input / output redirection. This can be used to integrate BD-CLI with other command-line utilities. An example is shown below. Here we are providing the name of the input file needed by BD-CLI from a text file:
Below you can see the output of the command (bd -h) which basically describes how to use this client:
Brown Dog Command-Line Interface (BD-CLI) ========================================= bd [OPTION] [FILE/DIRECTORY] ----------------------------- Command line interface to Brown Dog services. Use to convert files between formats and extract various derived products from file contents (e.g. tags, metadata, signatures, previews). -b set the BD URL (e.g. https://bd-api.ncsa.illinois.edu) -t set the token -v verbose output -w set wait time for conversions/extractions -h display help -o set output format --outputs list the available output formats for the given file --extractors list the available extractors for the given file --find search current directory for a file similar to the given file --bigdata use this flag if the file is large enough and it needs to be processed locally rather than using remote Brown Dog services **Examples:** List available output formats for given file: bd --outputs image.pcd Convert the given Kodak Photo CD image to a JPEG image. Produces file image.jpg: bd -o jpg image.pcd Convert a directory of images into the JPEG format: bd -o jpg images/ List available extractors for given file: bd --extractors image.jpg Extract data from files contents (e.g. tags, previews, analysis, and other derived products). Produces file image.json: bd image.jpg Chain conversion and extraction. Equivalent to the previous two examples: bd -o jpg image.pcd | bd Index files within a directory: bd images/ Search for a similar file within a directory that has already been indexed: bd --find /path/image.jpg Read input filename from a text file. This feature can be used to integrate BD-CLI with other programs by passing filename around. Here input.txt can contain one input filename: bd < input.txt bd -o jpg < input.txt |
