How to Permanently change PowerShell and CMD prompts

Question

PowerShell prompt can be changed by calling

Function prompt{"new_prompt "}

and on the cmd prompt can be changed by calling

prompt $g$g$s

Once the current window is closed all the changes are gone and one will have to change them again when opening new instances of PowerShell or cmd . How can one make these changes permanent?

Answer 1

For PowerShell you'd put your custom Prompt() function in the relevant profile .

function Prompt {
    "PS ${env:USERNAME}@${env:COMPUTERNAME} $(Get-Location)> "
}

For CMD you'd set/modify the PROMPT environment variable, eg via setx :

setx PROMPT "%"USERNAME"%"@"%"COMPUTERNAME"%"$s$m$p$g$s

Answer 2

You have profile where you can put initialization for your PowerShell command prompts.

Type $profile in your PowerShell command to see where it resides

Then modify it or create a new one if there doesn't exist one eg profile.ps1.

eg then add

function prompt { "PS " + $(get-date) ">"}
