# Linux Mint Wallpaper Retriever

# This is to facilitate the easy download of Linux mint backgrounds for Windows 10 users.
# (Mint has pretty good backgrounds, if you didn't know)

# This assumes you have WSL with Linux PowerShell installed.  Usage:

# source get-mind-wallpaper.sh

# this was written in WSL, to automate getting the nice Linux Mint backgrounds
# for use in Windows.  Puts these in a "mint-backgrounds" directory, opens them in explorer at the end.

# (this is mostly meant as a review for my GNU/Linux Bash scripting, it's nothing special.)


# BTW this assumes that your WSL username is the same as your Windows username!!!

# as desired here...
