Description

The Import-Alias cmdlet imports an alias list from a file.

Beginning in Windows PowerShell 3.0, as a security feature, Import-Alias does not overwrite existing aliases by default. To overwrite an existing alias, after assuring that the contents of the alias file is safe, use the Force parameter.

Examples

Example 1: Import aliases from a file

Import-Alias test.txt

This command imports alias information from a file named test.txt.

Parameters

-Confirm

Prompts you for confirmation before running the cmdlet.

Type:SwitchParameter
Aliases:cf
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Force

Allows the cmdlet to import an alias that is already defined or is read only. You can use the following command to display information about the currently-defined aliases:

Get-Alias | Select-Object Name, Options

If the corresponding alias is read-only, it will be displayed in the value of the Options property.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-LiteralPath

Specifies the path to a file that includes exported alias information. Unlike the Path parameter, the value of the LiteralPath parameter is used exactly as it is typed. No characters are interpreted as wildcards. If the path includes escape characters, enclose it in single quotation marks. Single quotation marks tell PowerShell not to interpret any characters as escape sequences.

Type:String
Aliases:PSPath
Position:Named
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:False

-PassThru

Returns an object representing the item with which you are working. By default, this cmdlet does not generate any output.

Type:SwitchParameter
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-Path

Specifies the path to a file that includes exported alias information. Wildcards are allowed but they must resolve to a single name.

Type:String
Position:0
Default value:None
Required:True
Accept pipeline input:True
Accept wildcard characters:True

-Scope

Specifies the scope into which the aliases are imported. The acceptable values for this parameter are:

  • Global
  • Local
  • Script
  • A number relative to the current scope (0 through the number of scopes, where 0 is the current scope and 1 is its parent)

The default is Local. For more information, see about_Scopes.

Type:String
Position:Named
Default value:None
Required:False
Accept pipeline input:False
Accept wildcard characters:False

-WhatIf

Shows what would happen if the cmdlet runs. The cmdlet is not run.

Type:SwitchParameter
Aliases:wi
Position:Named
Default value:False
Required:False
Accept pipeline input:False
Accept wildcard characters:False

Inputs

String

You can pipe a string that contains a path to this cmdlet.

Outputs

None

By default, this cmdlet returns no output.

AliasInfo

When you use the PassThru parameter, this cmdlet returns an AliasInfo object representing the alias.
