# Dec 16, 2021: Lorenz Kaestle - Bugfix when interface parameter was missing in combination with -g (6.12.2)
# Apr 27, 2022: Claudio Kuenzler - Allow skip temperature check (--skip-temp-check) (6.13.0)
# Apr 27, 2022: Peter Newman - Better handling of missing or non-executable smartctl command (6.13.0)
# Aug 2, 2022: Joe Vivona - Modified to run on pfSense boxes, which are FreeBSD Based but install things like PERL in difference locations
# Aug 2, 2022: Joe Vivona - Removed inline sudo for pfSense - since overall script is run in sudo mode and therefor impersonating
# Apr 29, 2023: Nick Bertrand - Show drive(s) causing UNKNOWN status using -g/--global check (6.14.0)
# Apr 29, 2023: Claudio Kuenzler - Add possibility to hide serial number (--hide-sn) (6.14.0)
# Apr 29, 2023: Claudio Kuenzler - Add default check on Load Cycle Count (ignore using --skip-load-cycles) (6.14.0)
# Aug 2, 2022: Joe Vivona - Modified to run on pfSense boxes, which ar FreeBSD Based but install things like PERL in difference locations. see line 1 above - pfSense path is /usr/local/bin/perl
