The use case is, on console I am passing argument list for exe in that arguments I am passing if else loop and value inside in it and I want to hide the value on console, the argument list coming from json template contains command too

Answer 1

and I want to hide the value on console,

What statement is causing the value to be displayed?

Can't you just set it to null when you're done referencing it.

$foo = $null  

Is this a scope problem?

$global:foo = $null

Answer 2

Sorry, I have no idea what you are trying to do. What .exe are you running? Are you passing code to this .exe?

Here is a Powershell script that accepts an input parameter and runs a program with that value. Note that what when I run it in the Powershell window, the $foo variable is empty because it's scope was in the script and it's value is gone because the script has terminated.

The character string "/user" displays in the console for 2 reasons.

1. The script intentionally outputs it. The "Calling whoami" statement can be removed which would prevent the display.
2. It was entered on the command line. Clear-Host will clear the screen.

Note that whoami.exe does not output anything that says "I was called with the /user switch". If the .exe that you are calling displays $foo then you have to capture its output and process it.

$z =  &c:\Windows\system32\whoami.exe $foo
