How to run a Powershell script through Extendscript?

[TheAzzam]

I'm thinking of the app.system command which can maybe run ps1 scripts through the command line, but the command line would need Bash installed. Is there a way without Bash being installed?

app.system( ".\C:\Users\DELL\Desktop\input_settings.ps1" + app.version)

[jazz-y · Accepted solution]

app.system('powershell.exe -ExecutionPolicy bypass -File "e:\\test.ps1"')

You might find this library I wrote helpful, you can save it as a .jsxinc (include) file.

Utility Pack Scripts created by David M. Converse ©2018-21

This script is a sample include file for scripters that contains a
template function to run command line actions in Windows
without the command line window showing. This function takes
either a native Powershell function or command prompt code,
writes it into a vbs file, and executes the vbs file to launch Powershell.

Syntax is critical, note all of the escaped characters!
