v019
Figured I should release this officially, since I haven't seen any recent bugs, and it's been a while. Finally, we're POSIX compatible!
- can now override default calculations of the "check_diff" variable
- made "trap" function when ending the program more universal
- thanks to @d3473r there's a sample systemd file if you wish to run the script at boot
- removed usage of the "seq" function
