How to remove the "username@host" from powershell prompt?

Question

I am using Windows Terminal(Preview) with shells like 1.PowerShell, 2.WSL in my Windows 10 machine. I installed the latest version of oh-my-posh and posh-git to customize the terminal. My current theme is Agnoster which gives a colorful custom prompt. But I want to get rid of the "username@host" from my prompt.

Eg:

Current => username@host D:\folder-name>

Needed => D:\folder-name>

I tried few things with $GitPromptSettings variable and also in GitPrompt.ps1 file which is inside the posh-git folder but with no use.

Also, since i have oh-my-posh and posh-git, does both have prompt customization properties or it is only from posh-git?

Any help is appreciated.

Answer 1

Answer 2

You have to set $DefaultUser before importing modules.

Example:

$global:DefaultUser = [System.Environment]::UserName
Import-Module posh-git 
Import-Module oh-my-posh
Set-Theme Paradox

OMG. Awesome. Thanks. It worked. But can you please explain what we are doing and how it is working? Because, i was thinking that, i should do something on the GitPrompt variable which is returned by posh.git – Candless

This is no longer working in Oh My Posh 3, see the answer by @Tica below: https://mcmap.net/q/1399066/-how-to-remove-the-quot-username-host-quot-from-powershell-prompt – Sempstress

Answer 3

In Oh My Posh 3, the method for hiding the username@host part has changed because the whole theme configuration has changed.

The username@host portion of the powerline comes from the "session" segment. The configuration options for session can be found here: https://ohmyposh.dev/docs/session

Interesting options are:

• display_user: boolean - display the user name or not - defaults to true
• display_host: boolean - display the host name or not - defaults to true
• default_user_name: string - name of the default user - defaults to empty
• display_default: boolean - display the segment or not when the user matches default_user_name - defaults to true

And the note on environment variables:

POSH_SESSION_DEFAULT_USER - used to override the hardcoded default_user_name property

Solution

Based on this, I made the following changes:

1. For the theme, I added the display_default: false property to the "session" segment:

   {
     "type": "session",
     // ....
     "properties": {
       "display_default": false
     }
   }```
   

2. In my powershell profile, I set the new environment variable to my own username: $env:POSH_SESSION_DEFAULT_USER = [System.Environment]::UserName

This makes the user@host part of the prompt disappear as long as I'm using my default username.

It's not clear from your answer wether you need to do 1. and 2. or just either one of them. The default location of the theme files could also be mentioned. – Brandenbrandenburg

Answer 4

You may check {theme's name}.psm1 in the Themes/ directory to understand how it works. The key is the following code.

e.g. Paradox.psm1

$user = $sl.CurrentUser
....
if (Test-NotDefaultUser($user)) {

        $prompt += Write-Prompt -Object "$user@$computer " -ForegroundColor $sl.Colors.SessionInfoForegroundColor -BackgroundColor $sl.Colors.SessionInfoBackgroundColor

}

if $DefaultUser is same to $user or is different $null, your powershell does not show $user@$computer.

Thanks. Actually I was going through the Agnoster.psm1 file to understand the logic. Ii will be easy if i could debug the file. Seems there is a way to debug. Let me check. Thanks Again. – Candless
