| i still have hopes it syncs, arent pipes file fifos or something
it makes no difference, you cannot sync something
which has not yet been written, and in the
examples it us very likely that date has not
had time to do all tge work it needs to do
before it can write anything.
In general, reads with small timeouts (like 0)
are only useful when they are in some kind of
loop which isdoing something useful while
waiting for input to (perhaps) arrive.
(This applies to sh scripts and any other
programming language - simply testing if there
is data avaikabke *now* is rarely, though not
never, useful).
