Hello,

I have a question here: who uses sbase and why?

Can't agree more.

Another non-POSIX feature I really like is the date -f- and the hability
to write dates like: 'last week', 'next month' ' 1jan + 14 days'. I
always fall back on C when I use busybox.

I don't know if it's relevant but today, the tiny core I use is busybox
so I don't know how it maters but:

- Busybox findutils:
