Core

The core asdf command list is rather small, but can facilitate many workflows.

Installation & Setup

Covered in the Getting Started guide.

Exec

asdf exec <command> [args...]

Executes the command shim for the current version.

Env

asdf env <command> [util]

Info

asdf info

A helper command to print the OS, Shell and asdf debug information. Share this when making a bug report.

Reshim

asdf reshim <name> <version>

This recreates the shims for the current version of a package. By default, shims are created by plugins during installation of a tool. Some tools like the npm CLI allow global installation of executables, for example, installing Yarn via npm install -g yarn. Since this executable was not installed via the plugin lifecycle, no shim exists for it yet. asdf reshim nodejs <version> will force recalculation of shims for any new executables, like yarn, for <version> of nodejs .

Shim-versions

asdf shim-versions <command>

Lists the plugins and versions that provide shims for a command.

As an example, Node.js ships with two executables, node and npm. When many versions of the tools are installed with asdf-nodejs shim-versions can return:

➜ asdf shim-versions node
nodejs 14.8.0
nodejs 14.17.3
nodejs 16.5.0

➜ asdf shim-versions npm
nodejs 14.8.0
nodejs 14.17.3
nodejs 16.5.0

Update

asdf has a built in command to update which relies on Git (our recommended installation method). If you installed using a different method you should follow the steps for that method:

Method	Latest Stable Release	Latest commit on master
asdf (via Git)	asdf update	asdf update --head
Homebrew	brew upgrade asdf	brew upgrade asdf --fetch-HEAD
Pacman	Download a new PKGBUILD & rebuild or use your preferred AUR helper
