Last active April 21, 2022 05:39
This function will use the PowerShell Parser, and the Get-AWSCmdletName cmdlet (found in AWS.Tools.Common, AWSPowerShell or AWSPowerShell.NetCore) to find and output all AWS Cmdlets from a script. This can be used to assist with migrations to the modular AWS Tools for PowerShell.
function Get-AWSCommandsFromFile {
[CmdletBinding()]
param (
[ValidateScript({Test-Path -Path $_ -PathType Leaf})]
$FilePath
)
$awsCommands = @{}
$tokens = [System.Management.Automation.PSParser]::Tokenize((Get-Content -Path $FilePath -Raw), [ref]$null)
