Описание
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.
Примеры
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 -ne
(not equal) operator 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. The Force parameter can't
remove Constant aliases.
Параметры
-Force
Indicates that the cmdlet removes an alias, including aliases with the Option property set to ReadOnly. The Force parameter can't remove an alias with an Option property set to Constant.
