Examples of using the install-powershell.ps1 script from the PowerShell Repo

Install-PowerShell.ps1-enhanced-Readme.md

This extends the information available in the Install-PowerShell.ps1-Readme.md to tie in with the additional background information in the following Blog Post Installing PowerShell Side by Side for testing purposes

This is an example of what you might get from using any of the scripts in this gist.

VersionInstallSetup.ps1

#  This example Script gives you lots of different ways to install the following random matrix of PowerShell versions

## It is **NOT** intended to be run as a script however will work 
## It is however intended as a reference for how to install different versions of PowerShell in different ways 
## to the Install-PowerShell.ps1 Readme file https://github.com/PowerShell/PowerShell/blob/master/tools/install-powershell.ps1-README.md

#  Daily
#  Stable
#  Preview
#  LTS
#  7.4.0-preview.4
#  7.3.4
#  7.3.3
#  7.2.10

# 

# All versions will be side by side installed in C:\ (So needs to be run as admin)
# However, you can change the destination folder by changing the -destination parameter as that you can install it anywhere you want instead
# If you don't provide a destination it will install in current users local appdata folder (on Windows that is C:\Users\username\AppData\Local\) or will install in "~/.powershell" on Linux and macOS
