<# .SYNOPSIS Tests whether a name must not be used for a PowerStub alias. .DESCRIPTION Aliases become global commands, so a name matching a critical system command would silently shadow it in every session that loads the module. .PARAMETER Name The alias name to test. .INPUTS None. You cannot pipe objects to this function. .OUTPUTS System.Boolean. True when the name is reserved. #> function Test-PowerStubReservedName { [CmdletBinding()] [OutputType([bool])] param ( [Parameter(Mandatory)] [string] $Name ) $reservedNames = @('cd', 'ls', 'dir', 'where', 'git', 'python', 'node', 'npm', 'set', 'del', 'rm', 'cp', 'mv', 'cat', 'echo', 'type', 'cls', 'clear', 'exit', 'push', 'pop') # Include contextual keywords and future-reserved words, which Get-Command does # not report as commands.
