Invoke-History [[-Id] <string>] [-Confirm] [-WhatIf] [<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 Get-History.
Parameters
-Id <string>
Identifies a command in the history. You can type the ID number of the command or the first few characters of the command.
If you type characters, Invoke-History matches the most recent commands first. If you omit this parameter, Invoke-History runs the last (most recent) command. The parameter name ("id") is optional. To find the ID number of a command, use Get-History.

Notes
The session history is a list of the commands entered during the session along 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.
You can also refer to Invoke-History by its built-in aliases, "r" and "ihy". For more information, see about_Aliases.
Example 1
| Copy Code |
|
|---|---|
C:\PS>invoke-history |
|
Description
-----------
This command runs the last (most recent) command in the session history. You can abbreviate this command as "r" (think "repeat" or "rerun"), the alias for Invoke-History.
Example 2
| Copy Code |
|
|---|---|
C:\PS>invoke-history -id 132 |
|
Description
-----------
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 "Invoke-History 132", "ihy 132", or "r 132".
Example 3
| Copy Code |
|
|---|---|
C:\PS>invoke-history get-pr |
|
Description
-----------
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, beginning with the most recent commands. This command uses the ID parameter, but it omits the optional parameter name.
Example 4
| Copy Code |
|
|---|---|
C:\PS>invoke-history (16..24), 27 |
|
Description
-----------
This command runs commands 16 through 24 and 27. You can list multiple IDs and ID ranges separated by commas.
Example 5
| Copy Code |
|
|---|---|
C:\PS>get-history -id 255 -count 7 | invoke-history |
|
Description
-----------
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 executes them.
