PowerShell for Administrators

ref. Joe Dow

run \windows powershell ISE as Admininstrator …

goto cmd and

get-service -name “*net*”

get-service | out-file c:\services.txt

get-help Get-Service -examples … get-service could be any “commandlet”
dont like seeing help in command prompt ? -online to see in the browser

this code is case insensitive

get-help get-childitem -full look for alias names under NOTES

get-service | where-object {$_.status -eq “stopped”}

| get-member

> function add [ENTER]
>>> {
>>> $add = [int] (2+2)
>>> write-output “$add”
>>> }
add
will return result

-WhatIf and -Confirm
Get-Service | Stop-Service -confirm // this will toggle every running service

ISE integrated scripting environment, then goto Add-ons and add to view “command add-ons”

running Remote Powershell Tab in ISE great tool to take advantage of

working with output

get-service | sort-object -property status | format-list displayname, status, required

out-file c:\result.txt

export-csv c:\result.txt

grid view to preview filterings

… | out-gridview //or to table format
