Sample signed PowerShell script

# Directory structure is as follows:
# C:\example\
#     |----your_signed_script.ps1
#     |----tm_script_parameter.txt

# Command line example for launching PowerShell:
# PowerShell.exe -ExecutionPolicy RemoteSigned -File "C:\example\your_signed_script.ps1" "C:\example\tm_script_parameter.txt"

# Follow a simple format for your signed script to handle script parameters:

# Use utf8 encoding:
$OutputEncoding = [console]::InputEncoding = [console]::OutputEncoding = [Text.UTF8Encoding]::UTF8

# Read raw parameter string from $args[0]:
$ArgString = Get-Content -Path $args[0] -Encoding UTF8

# Split raw string:
$InputArgs = $ArgString -split '\s+(?=(?:[^"]*"[^"]*")*[^"]*$)' | Where-Object { $_ -ne '' } | ForEach-Object { $_.Trim('"') }

function EntryPoint {
    #####################################################
    # Your script content goes in the EntryPoint function.
    
    # Specify function parameters:
    [CmdletBinding()]
    param (
        [Parameter()][string]$Id,
        [Parameter()][string]$Name
    )
    
    Write-Host "ID: $Id, Name: $Name"

}

# Change the parameter string array to Params variables:
$NamedParams = @{}
$PositionalParams = @()

for ($i = 0; $i -lt $InputArgs.Length; $i++) {
    $Arg = $InputArgs[$i]

    if ($Arg.StartsWith("-")) {
        # Find named parameter:
        $ParamName = $Arg
        $ParamValue = $InputArgs[$i + 1]
        $NamedParams[$ParamName] = $ParamValue
        $i++
    } else {
        # Find positional parameter:
        $PositionalParams += $Arg
    }
}

# Call EntryPoint function with the Params variables:
EntryPoint @NamedParams @PositionalParams
