Work with Files and Data on the Command Line Using Wolfram Cloud

WolframScript can operate on files without any local kernel present using the Wolfram Cloud. Start by producing a text file using a cloud kernel.

Create a script file called FindPath.wls using a cloud kernel as the interpreter with the following content.

#!/usr/local/bin/wolframscript -cloud -print -format PNG samples = ImportString[$ScriptInputString, "JSON"]; order = Last[FindShortestTour[samples]]; tour = samples[[order]]; Show[ListPlot[samples], Graphics[Line[tour]]]

The script can be executed from the command line using the local text file as input.

Import the code into a notebook.

Click for copyable input
Import[FileNameJoin[{$HomeDirectory, "examples", "tour.png"}], "PNG"]
