Display PowerShell Output

PowerShell is a cross-platform shell and scripting language that allows users to interact with the operating system. Flows support the implementation of PowerShell scripts to retrieve system information and automate administrative operations.

What Display PowerShell Output can do

• Run PowerShell script (Core.Process.StartProcess) — runs powershell with -NoProfile -Command '$variableName = "Hello World!"; Write-Output $variableName', captures stdout into msg.powershell_output.
• Trim output (Core.Programming.Function) — strips trailing CR/LF from msg.powershell_output.
• Message Dialog (Core.Dialog.MessageBox, optType: info) titled Output from PowerShell script: shows msg.powershell_output, then Core.Flow.Stop.

Behind the scenes

• Write-Output sends the value on the success stream; Core.Process.StartProcess captures it as stdout. A bare $variableName line would behave identically — the explicit form is kept for clarity.
• -NoProfile skips the user's PowerShell profile so the script starts faster and stays deterministic across machines.
• The captured text typically has a trailing CR/LF, which the Function node trims before the dialog.
