TL;DR

This is a note that I found out Microsoft PowerShell can act like Bash/Zsh which I much familiar with. Because of the work, pretty much whole operating system move to windows. It is so much pain to work without using any shell. The main reason is that I so much used to use (neo)vim as my code editor. But luckily (neo)vim built for windows (phew~). Ok, back to the title, this is a step by step note that I dig into PowerShell and Windows.

  • Create $PROFILE for PowerShell if not exist (like .bashrc or .zshrc)

    1. Test if Profile exist
      1

      Test-Path $PROFILE

    ❗If return is false meaning there is NO profile found then jump to step 2. ❗If return is true meaning there IS profile found then jump to step 3.

    1. Create Profile
      1

      New-Item -Type File -Force $PROFILE

    ⚠ (Caution) these will erase the exist profile with new empty one.

    1. Varify Profile path
      1

      echo $PROFILE

    It normally locate in ~/Documents/WindowsPowerShell/Microsoft.PowerShell_profile.ps1

  • Install oh-my-posh Theme like powerlevel10k

    1. Installation

      1

      Install-Module oh-my-posh -Scope CurrentUser

    2. List all themes and remember the name of theme you like

      1

      Get-PoshThemes -list

    3. Add theme to Profile

      1

      Set-PoshPrompt -Theme <Theme name>

    Personally I use honukai for the simplicity.

    1. Source the Profile or restart the Terminal to take effect.
