Automating the deletion of GOES-16 and GOES-17 images received using GOESTools the ghetto way.

I was having trouble with my hard drive filling up while pulling images from GOES-16 and GOES-17 satellites. 32gb filles up really quick on my odroid! So I wrote a ghetto little script that removes files older than 2 days, every day, except for the full color/ full disk images which are the ones I want to keep. I also leave the national weather service images since they take up very little space....

Making wxtoimg work on your 64 bit arm Odroid N2+

Recently I’ve gotten into RTL-SDR / HAM Radio and have been working on getting this cool package of scripts working that’ll automatically grab NOAA / ISS and METEOR data and decode it! Ran into an issue today with wxtoimg. Since it’s abandonware it’s not possible to compile it, and the only binaries are for 32bit arm, not 64bit, which is what my Odroid N2+ is. Here’s the quick way of making it work on your 64bit arm computer....
