Sometimes, while you’re poking around in the console, you want to re-run the last command. Sure, you can hit the up arrow and enter, but PowerShell always gives you multiple ways to do things.

It’s easy, using the Invoke-History cmdlet. You can also use its alias which is just r. Running that cmdlet without any parameters will run the last command from the console. Alternatively, you can specify a value for the ID parameter, and run one from further back in your history.

How do you find out what those IDs should be? Using Get-History to see everything you’ve run in this session, and the ID number for that command.
