This is a straightforward & clear-cut guide based on Scott Hanselman's YouTube tutorial.

Let's get you set up!

Install Powershell(.NET Core-powered cross-platform Powershell)

winget install Microsoft.PowerShell

Install Windows Terminal

winget install Microsoft.WindowsTerminal

Make PowerShell as your default terminal on Windows Terminal

Go to Settings

Click on Default profile and select PowerShell and save the changes.

Then go to Profiles > PowerShell > Additional Settings > Appearance.

Here you can customize your fonts by choosing a suitable font with lots of Glyphs.

Navigate to the following link to explore & download all the trendiest developer nerd fonts: nerdfonts.com/font-downloads

So, we will go with this, github.com/ryanoasis/nerd-fonts/releases/do..

Choose FiraCode NF as Terminal Font.

Install Oh My Posh

winget install JanDeDobbeleer.OhMyPosh -s winget

• For the PATH to be reloaded, a restart of your terminal is advised

Enter the following code in Terminal to get the exact location of the PowerShell profile.

 echo $profile

If you don't see any folder titled PowerShell in Documents, Make new folder in that name anyway.

Inside that folder, create a file Microsoft.PowerShell_profile.ps1 where we're gonna add our functionalities.

Following json is being used as theme property to modify Oh My Posh options.

theme.json:

{% embed gist.github.com/hanancs/75f3e1d8095e328c279.. %}

Download theme.json and locate it wherever you want, I'm letting it beside the Microsoft.PowerShell_profile.ps1 file.

Open Microsoft.PowerShell_profile.ps1 and add the following code and save it.

oh-my-posh --init --shell pwsh --config C:\Users\{YOUR PC USER NAME}\Documents\PowerShell\theme.json | Invoke-Expression

Restart your terminal. You will see the difference.

Run the following code in the terminal

PSReadLine will help you this way:

Enable Predictive Intellisense

Predictive intellisense will gather guesses as much as possible.

Add these lines to Microsoft.PowerShell_profile.ps1 file.

Set-PSReadLineOption -PredictionViewStyle ListView
Set-PSReadLineOption -EditMode Windows
