AvoidGlobalAliases

Severity Level: Warning

Description

Globally scoped aliases override existing aliases within the sessions with matching names. This name collision can cause difficult to debug issues for consumers of modules and scripts.

To understand more about scoping, see Get-Help about_Scopes.

NOTE This rule is not available in PowerShell version 3 or 4 because it uses the StaticParameterBinder.BindCommand API.

How

Use other scope modifiers for new aliases.

Example

Wrong

New-Alias -Name Name -Value Value -Scope Global

Correct

New-Alias -Name Name1 -Value Value
