It's easier if you start your own thread.

Thanks for that link has a few things I didn't know about and easily understood how to enter in the CLI. :)
I always ran msdos with 4dos as the command.com
I ran windows with TakeCommand
Linux Mint I run with ZSH ( for terminal commands)
I like using the terminal whenever possible as faster in every respect especially with aliases.

sudo apt install zsh
