Installing Miller

You can install Miller for various platforms as follows.

Download a binary:

  • You can get binaries for several platforms on the releases page.
  • You can get latest (head) builds for Linux, MacOS, and Windows by visiting, selecting the latest build, and clicking Artifacts. (These are retained for 5 days after each commit.)
  • See also the build page if you prefer to build from source.

Using a package manager:

  • Linux: yum install miller or apt-get install miller depending on your flavor of Linux, or Homebrew.
  • MacOS: brew update and brew install miller, or sudo port selfupdate and sudo port install miller, depending on your preference of Homebrew or MacPorts.
  • Windows: choco install miller using Chocolatey.
  • Note: Miller 6 was released 2022-01-09; several platforms may have Miller 5 available.

See also:

Note that the Miller releases page, brew, macports, chocolatey, and conda tend to have current versions; yum and apt-get may have outdate versions depending on your platform.

As a first check, you should be able to run mlr --version at your system's command prompt and see something like the following:

mlr --version
mlr 6.0.0

A note on documentation:

  • If you downloaded the Miller binary from a tagged release, or installed it using a package manager, you should see a version like mlr 6.0.0 or mlr 5.10.3 -- please see the release docs page to find the documentation for your version.
  • If you installed from source or using a recent build artifact from GitHub Actions, you should see a version like mlr 6.0.0-dev -- is the correct reference, since it contains information for the latest contributions to the Miller repository.

As a second check, given example.csv you should be able to do

mlr --csv cat example.csv
mlr --icsv --opprint cat example.csv
