Wolfram Computation Meets Knowledge

How do I specify which kernel WolframScript should use?

With WolframScript, you can run Wolfram Language code from your operating system’s command line, either through a Wolfram kernel installed as part of a Wolfram product or in the Wolfram Cloud.

If you have multiple Wolfram products installed on your machine and want WolframScript to use a specific kernel, launch WolframScript from the command line with the command:

wolframscript -config WOLFRAMSCRIPT_KERNELPATH="Full path to kernel"

For example, to use the Wolfram kernel included with a default installation of the Wolfram Engine on Windows, the command is:

wolframscript -config WOLFRAMSCRIPT_KERNELPATH="C:\Program Files\Wolfram Research\Wolfram Engine\12.3\WolframKernel.exe"

For a default installation of the Wolfram Engine on macOS, the command is:

wolframscript -config WOLFRAMSCRIPT_KERNELPATH="/Applications/Wolfram Engine.app/Contents/MacOS/WolframKernel"

For a default installation of the Wolfram Engine on Linux, the command is:

wolframscript -config WOLFRAMSCRIPT_KERNELPATH="/usr/local/Wolfram/WolframEngine/12.3/Executables/WolframKernel"

This setting for WolframScript will be preserved until another program containing a Wolfram kernel is installed or the setting is manually changed.
