Windows PowerShell Core Bootstrapper

A script to install and configure a Windows PowerShell Core environment powered by Oh My Posh, for use in Windows Terminal.

Designed to be largely non-opinionated, non-clobbering, and repeatable.

Utilises the Windows Package Manager over other third-party options for lightweight and as-native application installation.

Usage

The script can be invoked remotely with defaults via the following command:

irm "https://raw.githubusercontent.com/jacobjmarks/pwsh/main/bootstrap.ps1" | iex

If you'd like to stabilise the script against changes, replace main with your commit hash of choice.

Advanced Usage

For advanced usage scenarios and customisation, download the script and utilise the available CLI arguments:

irm "https://raw.githubusercontent.com/jacobjmarks/pwsh/main/bootstrap.ps1" -OutFile bootstrap.ps1
Get-Help -Detailed .\bootstrap.ps1

Available Parameters

Parameter	Type	Description	Default
-Theme	string	Oh My Posh theme to configure for use	"paradox"
-NerdFont	string	Nerd Font to install.	"Hack"
