Terminal-Icons Module

In PowerShell, when you import a module using Import-Module, it only affects the current session.

To make the module available in all future sessions, you can add the import command to your PowerShell profile. The profile is a script that runs when you start a new session. Here’s what you can do:

Open your PowerShell profile script. You can check if you already have a profile by running:

Test-Path $profile

If it returns False, you can create a profile script. Run the following to create a profile:

New-Item -Type File -Path $profile -Force

Open the profile script in your preferred text editor. You can use the following command:

notepad $profile

Add the Import-Module command to this script, like so:

Import-Module -Name Terminal-Icons

Save and close the profile script.

Now, every time you start a new PowerShell session, it will automatically import the Terminal-Icons module. This ensures that the module is available in all future sessions.

oh-my-posh Module

You can import Oh-My-Posh in your PowerShell profile along with the Terminal-Icons module.

Import-Module -Name Terminal-Icons
Import-Module -Name oh-my-posh

# Set the theme. You can choose a different theme if you prefer.
Set-PoshPrompt -Theme Agnoster

Oh-My-Posh is not a traditional PowerShell module that you can import using the Import-Module cmdlet. Instead, it’s a separate PowerShell module that provides prompt theming functionality for your PowerShell prompt.

To install Oh-My-Posh, you typically use a package manager for PowerShell like PowerShellGet.

# Install-Module -Name ModuleName
Install-Module -Name oh-my-posh -Scope CurrentUser

Check if PowerShellGet module is available:

Get-Module -ListAvailable -Name PowerShellGet

Check if the PackageManagement module is available

Get-Module -ListAvailable -Name PackageManagement

If you haven’t installed PowerShellGet yet, you can do so by running:

Install-Module -Name PowerShellGet -Force -AllowClobber
