WinScreeny

I took one of the three Github WinScreeny bash scripts and modified it to look like this:

Here is the modified code:

I won't spend a lot of time dissecting it but you will notice it's a hybrid of some Linux kernel stuff and some Windows kernel stuff.

For example this Linux kernel line displays your CPU information:

cpu=$(awk -F':' '/model name/{ print $2 }' /proc/cpuinfo | head -n 1 | tr -s " " | sed 's/^ //')

On the other hand this Windows kernel line displays your motherboard model:

board=`/mnt/c/Windows/System32/wbem/WMIC.exe baseboard get product | tail -2 | tr -d '\r '`

Weather, Calendar and Time

Some people like the top part of the Ubuntu Bash on Windows 10 (WSL) terminal splash screen. If you would like the Weather, Calendar and current Time to display you can find the instructions here: How can I get this terminal splash screen?
