A command prompt is used to prompts the user to action, current status, such as the current directory, the username and device name or others variables/function user-defined.

Define a function called Prompt and put it into the PowerShell profile, to view a profile path, display the value of the $PROFILE variable.

Sample

A unix-like prompt here:

Function Prompt {
    $CurrentDir = Split-Path $PWD -Leaf

    if ($PWD -like (Get-PsProvider 'FileSystem').Home) {
        $CurrentDir = '~'
    }

    # Python Pipenv
    # if ($env:PIPENV_ACTIVE -eq 1) {
    #     $venv = (($env:VIRTUAL_ENV -split "\\")[-1] -split "-")[0]
    #     Write-Host ("($venv) ")  -NoNewLine -ForegroundColor Red
    # }
    
    if (([Security.Principal.WindowsPrincipal] [Security.Principal.WindowsIdentity]::GetCurrent()).IsInRole([Security.Principal.WindowsBuiltInRole]::Administrator)) {
        $Symbol = '#'
    } else {
        $Symbol = '$'
    }

    Write-Host ("`[$env:USERNAME@$env:COMPUTERNAME $CurrentDir`]$Symbol")  -NoNewLine -ForegroundColor DarkGreen
    return " "
}
