Add entries to the end of the session history (the commands entered during the current session).

      Add-History [[-inputObject] PSObject[]] [-passthru] [CommonParameters]

    -inputObject PSObject[]
        Adds the specified HistoryInfo objects to the session history. You can 
        use this parameter to submit a HistoryInfo object from Get-History, Imp
        ort-Clixml, or Import-Csv to Add-History.

    -passthru SwitchParameter
        Passes the object created by this cmdlet through the pipeline. 
        By default, this cmdlet does not pass any objects through the pipeline.


Export session history to a file :

PS C:\> get-history | export-csv E:\SessionHist.csv

Import session history from a file (this could be a different session on a different machine):

PS C:\> import-csv SessionHist.csv | add-history

You can also pipe commands directly from get-history to add-history which will re-arrange the order of items in the command line history. Piping history command (either from file or from get-history) to invoke-history will actullly run the commands.
