SYNOPSIS

Runs commands from the session history.

SYNTAX

Invoke-History [[-Id] <String>] [-WhatIf] [-Confirm] [<CommonParameters>]

DESCRIPTION

The Invoke-History cmdlet runs commands from the session history. You can pass objects representing the commands from Get-History to Invoke-History, or you can identify commands in the current history by using their ID number. To find the identification number of a command, use the Get-History cmdlet.

EXAMPLES

Example 1: Run the most recent command in the history

PS C:\>Invoke-History

This command runs the last, or most recent, command in the session history. You can abbreviate this command as r, the alias for Invoke-History.

Example 2: Run the command that has a specified ID

PS C:\>Invoke-History -Id 132

This command runs the command in the session history with ID 132. Because the name of the Id parameter is optional, you can abbreviate this command as the following: Invoke-History 132, ihy 132, or r 132.

Example 3: Run the most recent command by using the command text

PS C:\>Invoke-History -ID get-pr

This command runs the most recent Get-Process command in the session history. When you type characters for the Id parameter, Invoke-History runs the first command that it finds that matches the pattern, starting with the most recent commands.

Example 4: Run a sequence of commands from the history

PS C:\>16..24 | ForEach {Invoke-History -Id $_ }

This command runs commands 16 through 24. Because you can list only one ID value, the command uses the ForEach-Object cmdlet to run the Invoke-History command one time for each ID value.

Example 5: Run several commands by using Get-History

PS C:\>Get-History -Id 255 -Count 7 | Invoke-History

This command runs the 7 commands in the history that end with command 255, typically 249 through 255. It uses the Get-History cmdlet to retrieve the commands. The pipeline operator (|) passes the commands to Invoke-History, which runs them.

CommonParameters

This cmdlet supports the common parameters: -Debug, -ErrorAction, -ErrorVariable, -InformationAction, -InformationVariable, -OutVariable, -OutBuffer, -PipelineVariable, -Verbose, -WarningAction, and -WarningVariable. For more information, see about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).

INPUTS

System.String

You can pipe a history ID to this cmdlet.

OUTPUTS

None

This cmdlet does not generate any output, but output might be generated by the commands that Invoke-History runs.

NOTES

  • The session history is a list of the commands entered during the session together with the ID. The session history represents the order of execution, the status, and the start and end times of the command. As you enter each command, Windows PowerShell adds it to the history so that you can reuse it. For more information about the session history, see about_History (http://go.microsoft.com/fwlink/?LinkID=113233).

    You can also refer to Invoke-History by its built-in aliases, "r" and "ihy". For more information, see about_Aliases (http://go.microsoft.com/fwlink/?LinkID=113207).
