Convert a small PS script into a long line in a .BATch file

Question

I have this PowerShell code that I got from the answer to this question; it show the location/dimensions of the cmd.exe window where the PS code run:

$Window         


        

Answer 1

I would go for the -EncodedCommand option here. You simply Base64 encode the entire powershell script and then pass the Base64 string as an argument to powershell.exe:

(assuming the script is here: C:\Path\To\Script.ps1)

PS C:\> $ScriptText  = Get-Content C:\Path\To\Script.ps1 -Raw
PS C:\> $ScriptBytes = [System.Text.Encoding]::Unicode.GetBytes($ScriptText)
PS C:\> $EncCommand  = [System.Convert]::ToBase64String($ScriptBytes)

$EncCommand now contains the Base64 encoded command, ready for use inside cmd.exe (or your batch file for that matter):
