Oh, My, GOD! You may think I was just doing afk the past week or so, But, You'd be wrong, So, So, SO wrong. I've spent almost every day working as hard as I can on this commit here. It should work perfectly now, It should properly exclude interfaces, And, It should automatically exclude inactive ones. More testing is needed, Especially testing of running the -e argument multiple times, I.E -e eth0 -e wlan0. Anyway, Thank you for reading, And for downloading.
