Through the Command Prompt, I am looking to open Powershell as Admin and pass a command for it to execute. The command is simple: remove all .txt files in a directory. I am having a difficult time passing this command into the Admin Powershell. Here's what I'm trying:
powershell -Command "Start-Process powershell -Verb runAs | Remove-Item -Path C:\MyFolder\*.txt"
So far, the Powershell window opens but nothing is executed.
You are just piping the $null output of Start-Process to Remove-Item, which makes no sense.
Your 2nd Powershell invocation should use -Command parameter:
powershell -command Start-Process powershell -Verb runAs -ArgumentList @('-Command', 'Remove-Item', \"'C:\MyFolder\*.txt'\")
The command-line that follows -command doesn't need to be quoted, which simplifies nested quoting.
The somewhat strange looking quoting for the Remove-Item argument is required to support path with spaces. First the backslash-escaped double quotes will be resolved by the cmd parser, finally the Remove-Item call will look like this:
Remove-Item 'C:\MyFolder\*.txt'
powershell -Command "start-process powershell -Verb RunAs -Args 'Remove-Item -Path C:\MyFolder\*.txt'"
you can also pass remove-item as args in string format
