Pattern: Overwriting built-in cmdlet

Issue: -

Description

This rule flags cmdlets that are available in a given edition/version of PowerShell on a given operating system which are overwritten by a function declaration. It works by comparing function declarations against a set of whitelists which ship with PSScriptAnalyzer. These whitelist files are used by other PSScriptAnalyzer rules.

Configuration

To enable the rule to check if your script is compatible on PowerShell Core on Windows, put the following your settings file.

@{
    'Rules' = @{
        'PSAvoidOverwritingBuiltInCmdlets' = @{
            'PowerShellVersion' = @("core-6.1.0-windows")
        }
    }
}

Parameters

PowerShellVersion

The parameter PowerShellVersion is a list of whitelists that ship with PSScriptAnalyzer.

Note: The default value for PowerShellVersion is "core-6.1.0-windows" if PowerShell 6 or later is installed, and "desktop-5.1.14393.206-windows" if it is not.
