Remove-Alias

  • Reference
Module:
Microsoft.PowerShell.Utility

Remove an alias from the current session.

Syntax

Remove-Alias
      [-Name] <String[]>
      [-Scope <String>]
      [-Force]
      [<CommonParameters>]

Description

The Remove-Alias cmdlet removes an alias from the current PowerShell session. To remove an alias with the Option property set to ReadOnly, use the Force parameter.

The Remove-Alias cmdlet was introduced in PowerShell 6.0.

Examples

Example 1 - Remove an alias

This example removes an alias named del that represents the Remove-Item cmdlet.

Remove-Alias -Name del

Example 2 - Remove all non-Constant aliases

This example removes all aliases from the current PowerShell session, except for aliases with the Options property set to Constant. After the command is run, the aliases are available in other PowerShell sessions or new PowerShell sessions.

Get-Alias | Where-Object { $_.Options -NE "Constant" } | Remove-Alias -Force

Get-Alias gets all the aliases in the PowerShell session and sends the objects down the pipeline. Where-Object uses a script block, and the automatic variable ($_) and Options property represent the current pipeline object. The parameter NE (not equal), selects objects that don't have an Options value set to Constant. Remove-Alias uses the Force parameter to remove aliases, including read-only aliases, from the PowerShell session.
