Export Alias - PowerShell


Export-Alias exports one or more PowerShell aliases to a specified file. This is useful for sharing or storing aliases for later use.


Export-Alias [-Alias] <Alias[]> -FilePath <String> [[-Force] [-Confirm] [-WhatIf]]


  • -Alias: Specifies the aliases to export. If not specified, all aliases in the current session are exported.
  • -FilePath: Specifies the path to the file where the aliases will be exported.
  • -Force: Overwrites the specified file if it exists.
  • -Confirm: Prompts for confirmation before exporting the aliases.
  • -WhatIf: Outputs what would happen if the command were run without actually performing the export.


Example 1: Export a single alias

Export-Alias Get-Host -FilePath "C:\aliases.txt"

Example 2: Export all aliases

Export-Alias -FilePath "C:\aliases.txt"

Common Issues

  • Error: “The alias ‘‘ does not exist.”

    Solution: Ensure that the specified alias exists in the current session.

  • Error: “The file ‘‘ is read-only.”

    Solution: Change the permissions of the file or use the -Force option to overwrite the file.


Export-Alias can be used in conjunction with other PowerShell commands, such as Import-Alias and Get-Alias.

Example: Export and import aliases between different sessions

# Export aliases to a file
Export-Alias -FilePath "C:\aliases.txt"

# Import aliases from the file
Import-Alias -FilePath "C:\aliases.txt"
  • Get-Alias: Gets information about the aliases in the current session.
  • Import-Alias: Imports aliases from a file or script.
