My PowerShell Scripting Notes

Running sequenced commands with && or || will usually result in the following error:

PS C:\Users\Example> echo Hello && echo World!

At line:1 char:12
+ echo Hello && echo World!
+            ~~
The token '&&' is not a valid statement separator in this version.

Spice up your Windows Command Prompts with Starship and Fzf

So what is this Starship Prompt all about?

  In a nutshell the Starship Prompt is a program and a collection of scripts that allows you to customize and enhance the command prompt beyond what it was originally intended for. Not only will you be able to change colors and display special fonts, but add additional qol features useful for people who spend a lot of time working within the command prompt.
  To further clarify - when I mentioned the command prompt, I don't just mean the Windows Command Interpretor or PowerShell, I'm also refering to Bash, Zsh, and a few other supported shells thus making Starship Prompt cross-platform. However for the scope of this guide we'll be focusing on the command prompts within the Windows Platform - PowerShell and Cmd.
