Quick example on how to mix WSL SQLPlus and WSL (Windows Subsystem for Linux) and powershell to access your database.

Enable WSL for Linux

1. First step is to enable Windows Subsystem for Linux in Windows 10. I like using the Linux tool called "pass" as my password manager. Since this tool works completly in the terminal I can use it to automate my workflows.

2. Once WSL is enabled proceed to install a Linux distribution for your WSL in the Windows Store. This will give you a debian based linux available for installing the next applications.
