Get-History - PowerShell command help and examples

Gets a list of the commands entered during the current session. (Get-History)


NAME
Get-History
SYNOPSIS
Gets a list of the commands entered during the current session.
SYNTAX
Get-History [[-Id] <Int64[]>] [[-Count] <int>] [<CommonParameters>]
DESCRIPTION
The Get-History cmdlet gets the session history, that is, the list of commands entered during the current session. Windows PowerShell automatically maintains a history of each session. You can save the session history in XML or CSV format. By default, history files are saved in the home directory, but you can save the file in any location.
PARAMETERS
-Count <int> Displays the specified number of the most recent history entries. The default is 32. If you use both the Count and Id parameters in a command, the display ends with the command specified by the Id parameter. Required? false Position? 2 Default value Accept pipeline input? false Accept wildcard characters? false -Id <Int64[]> Specifies the ID number of a command in the session history. Get-History gets only the specified command. If you use Id and Count, Get-History gets the most recent commands ending with the command specified by the Id parameter. Required? false Position? 1 Default value Accept pipeline input? true (ByValue) Accept wildcard characters? false <CommonParameters> This cmdlet supports the common parameters: Verbose, Debug, ErrorAction, ErrorVariable, WarningAction, WarningVariable, OutBuffer and OutVariable. For more information, type, "get-help about_commonparameters".
INPUTS
Int64 You can pipe a history ID to Get-History.
OUTPUTS
Microsoft.PowerShell.Commands.HistoryInfo Get-History returns a history object for each history item that it gets.
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 command history, see about_History. You can also refer to Get-History by its built-in aliases, "h", "history", and "ghy". For more information, see about_Aliases.

Examples

EXAMPLE 1
C:\PS>get-history
Description
----------- This command gets the 32 most recently submitted commands. The default display shows each command and its ID, which indicates the order of execution.
EXAMPLE 2
C:\PS>get-history | where-object {$_.commandLine -like "*service*"}
Description
----------- This command gets entries from the command history that include the word, "service". The first command gets the 32 most recent entries in the session history. The pipeline operator (|) passes the results to the Where-Object cmdlet, which selects only the commands that include "service".
EXAMPLE 3
C:\PS>get-history -id 7 -count 5 | export-csv history.csv
Description
----------- This command gets the five most recent history entries ending with entry 7. The pipeline operator (|) passes the result to the Export-Csv cmdlet, which formats the history as comma-separated text and saves it in the History.csv file. The file includes the data that is displayed when you format the history as a list, including the status and start and end times of the command.
EXAMPLE 4
C:\PS>get-history -count 1
Description
----------- This command gets the last (most recently entered) command in the command history. It uses the Count parameter to display just one command. By default, Get-History displays the most recent commands. This command can be abbreviated to "h -c 1" and is equivalent to pressing the up-arrow key.
EXAMPLE 5
C:\PS>get-history -count $MaximumHistoryCount
Description
----------- This command displays all of the commands saved in the session history. By default, $MaximumHistoryCount is 64, so this command can be abbreviated as "h -c 64".
EXAMPLE 6
C:\PS>get-history | format-list
Description
----------- This command displays all of the properties of entries in the session history. The pipeline operator (|) passes the result to the Format-List cmdlet, which displays all of the properties of each history entry, including the ID, status, and start and end times of the command.
