Magika CLI

This binary crate implements a command-line interface (CLI) to the library crate magika which provides file type detection with deep-learning.

Disclaimer

This project is not an official Google project. It is not supported by Google and Google specifically disclaims all warranties as to its quality, merchantability, or fitness for a particular purpose.

The magika library and this magika-cli binary are still unstable (as indicated by the major version of zero) and new versions might introduce breaking changes (all changes will follow cargo semver compatibility). In particular, version 0.1.0-rc.0 ships a new model in comparison to the Python binary and we would love feedback on GitHub.

Installation

To install the latest version from crates.io:

cargo install --locked magika-cli

It is also possible to install from the git repository, in which case the version (accessible with magika --version) will be suffixed by -dev (e.g. 0.1.0-dev) to indicate that the binary is the development version of the version prefix (e.g. 0.1.0 for the previous example).

To install the latest version from the git repository:

cargo install --locked --git=https://github.com/google/magika.git magika-cli

To install from a local clone of the git repository (possibly with custom changes):

git clone https://github.com/google/magika.git
cd magika
cargo install --locked --path=rust/cli

$ magika --help
Determines the content type of files with deep-learning

Usage: magika [OPTIONS] [PATH]...

Arguments:
  [PATH]...
          List of paths to the files to analyze.

          Use a dash (-) to read from standard input (can only be used once).

Options:
  -r, --recursive
          Identifies files within directories instead of identifying the directory itself

      --no-dereference
          Identifies symbolic links as is instead of identifying their content by following them

      --colors
          Prints with colors regardless of terminal support

      --no-colors
          Prints without colors regardless of terminal support

  -s, --output-score
          Prints the prediction score in addition to the content type

  -i, --mime-type
          Prints the MIME type instead of the content type description

  -l, --label
          Prints a simple label instead of the content type description

      --json
          Prints in JSON format

      --jsonl
          Prints in JSONL format

      --format <CUSTOM>
          Prints using a custom format (use --help for details).

          The following placeholders are supported:

            %p  The file path
            %l  The unique label identifying the content type
            %d  The description of the content type
            %g  The group of the content type
            %m  The MIME type of the content type
            %e  Possible file extensions for the content type
            %s  The score of the content type for the file
            %S  The score of the content type for the file in percent
            %b  The model output if overruled (empty otherwise)
            %%  A literal %

  -h, --help
          Print help (see a summary with '-h')

  -V, --version
          Print version

See the docs on Magika's output for more details about the output format.
