Module for searching your full PowerShell command history

Door Jan Steenbeek In SharePoint

By default the Get-History cmdlet only returns lines from your current session. Therefore I’ve created a small module that gets history items from your full history, by default the most recent 4096 commands.
It features an easy search option and a few switches for case sensitivit and uniqueness.

To have it automatically available every time you start PowerShell do the following.

1. Find a module path by running

$env:PSModulePath

2. Select one. I picked “C:UsersjgsteOneDriveDocumentenWindowsPowerShellModules”
3. Ensure this folder exists, else create it
4. Create a subfolder “FullHistory”
5. Save the code below as “FullHistory.psm1” in the new folder
6. Start a new PowerShell session. Get-FullHistory should be available.

Function Get-FullHistory {

<#
.Synopsis
