A few problems with these one-liners:
not every 'mount' formats options like (opt1,opt2), some use (opt1, opt2), which impacts column -t output on filesystems with lots of options;
the event indicator !! is a bash-ism;
watch seems to be linux/GNU only, not available elsewhere, and on FreeBSD it is a totally different command:
watch(8) - snoop on another tty line;
--max-depth is a GNU du extension;
sort's -k option takes a initial number, i.e. '4', not '+4' which is an invalid field specification (but I guess it works with GNU sort).
