fragment here, other people spotted that.
The fragmentation is independent on the dd options used. Also "| cat" does the
same.
stdbuf is not available on all platforms, especially on those who do not have a
similar
external printf:
/usr/bin/printf "\xf5\xee\xbe\xe5&quo

env or exec: never thought about it (thanks!) but as both are external
commands, that would mean upon every call one additional external program.
(yes, I know that there is such thing as a fs buffer). Subshells also costs
resources. As this is a core function I am happy for every homeopathic dose
of time I safe here :-)

a performance penalty and other strange effects, e.g.
if the first segment is really small, some devices reject the ClientHello.
If there's a workaround, please let me know. (tried to add "%b" with no
effect). Otherwise I believe it's a bug.

Hi folks,
I am going nuts trying to read the output of a mysql select statement into

approaches, but every jump was somewhat short, it

It never results in every line of the mysql output becoming an array

I really tried finding out myself, but I am stuck, so please can someone

Hi folks,
I am looking for a possiblity to redirect error output into a variable:
Instead of redirecting to a file
( e.g.
command 2>>errorlogfile
)
I would like to redirect into a variable.
Is this generally possible?

Hi folks,

bash's error messages?
I find it often quite misleading and would like to know what I am

Any hint or help is appreciated.

Oh Mike,
thanks a lot for such detailled and well structured clarification! That

Many thanks!
