PowerShell: Command history

Tab completion allows to complete a command from the history by entering a hash sign # followed by the text fragment that is to be searched in the history:

PS C:\> #invoke

If the # is followed by a number, the tabulator will insert the text of the command whose id corresponds to this number.

There are two histories:

• The session history
• The history maintained by the PSReadLine module

The default location of the file that stores the command history on Windows seems to be $env:APPDATA\Microsoft\Windows\PowerShell\PSReadline\ConsoleHost_history.txt

The PsReadLine options

• AddToHistoryHandler
• HistoryNoDuplicates
• MaximumHistoryCount (Compare with the $MaximumHistoryCount preference variable)
• HistorySearchCursorMovesToEnd
• HistorySearchCaseSensitive
• HistorySavePath
• HistorySaveStyle
