Here is my custom Powershell prompt

LONG DESCRIPTION

    The Windows PowerShell command prompt indicates that Windows PowerShell

    is ready to run a command:

        PS C:\>

    The Windows PowerShell prompt is determined by the built-in Prompt

    function. You can customize the prompt by creating your own Prompt

    function and saving it in your Windows PowerShell profile.

#>

One of my biggest issues with the default prompt is that I work with a lot of nested folders and network shares. It makes the path so long because the path is in there. So I change my prompt to just show the current folder and place the full path in the tittle bar.

One other thing I do is add basic command logging. I would use transcripts, but I don't want something that verbose. So I just save my last command to a text file whenever I run it.

The last thing I so is calculate where in the history the next command will be and add that to my prompt.

Here is my prompt function:

$PSLogPath = ("{0}{1}\Documents\WindowsPowerShell\log\{2:yyyyMMdd}-{3}.log" -f $env:HOMEDRIVE, $env:HOMEPATH,  (Get-Date), $PID)

Add-Content -Value "# $(Get-Date) $env:username $env:computername" -Path $PSLogPath

Add-Content -Value "# $(Get-Location)" -Path $PSLogPath

function prompt

{

    $LastCmd = Get-History -Count 1

    if($LastCmd)

    {

        $lastId = $LastCmd.Id

       

        Add-Content -Value "# $($LastCmd.StartExecutionTime)" -Path $PSLogPath

        Add-Content -Value "$($LastCmd.CommandLine)" -Path $PSLogPath

        Add-Content -Value "" -Path $PSLogPath

    }

    $nextCommand = $lastId + 1

    $currentDirectory = Split-Path (Get-Location) -Leaf

    $host.UI.RawUI.WindowTitle = Get-Location

    "$nextCommand PS:$currentDirectory>"

}
