PowerShell 3.0 -PassThru

PowerShell 3 -PassThru Parameter

PowerShell' s -PassThru parameter has found signficantly more uses in PowerShell 3.0.

In a nutshell -PassThru returns the results of a command that would otherwise be silent.

• Example 1: Out-GridView -PassThru
• Launching PowerShell 3.0 in Windows 8
• What Else Is New In PowerShell 3.0?

 ♦

Example 1: Out-GridView -PassThru

Let us take this example where we are using PowerShell 3.0 to display the processes.

The benefit of the -PassThru parameter comes when you select rows with the mouse, and then click OK.  The result is that PowerShell refreshes the output. 

Take the screenshot to the right where I have selected just 5 rows,  dlhost, LogonUI, lsass, MsMpEng and SearchIndex.  When I pressed ' OK' , the result was a display with just those 5 rows.

Launching PowerShell v 3.0

This is how to get started from the Metro user interface in Windows 8.

• From anywhere in the Metro UI, press the ' p' key.  You should see a list of the programs and Apps beginning with ' p' .
• At this point you could ' Pin' the ' Windows PowerShell ISE' by right-clicking and selecting ' Pin' at the bottom right of the screen.
• Incidentally, I prefer the GUI (ISE) version to the plain command line Windows PowerShell.
• I like to drag the PowerShell ISE tile to the left of my screen because it' s one of the most important Windows 8 Tiles that use.
