[Message part 1 (text/plain, inline)]
Hi,

I have a small problem with tee, which could be exemplified by the
following code:

wc -l largefile
> 235324 largefile
cat largefile |tee -i >(head > /dev/null) |wc -l
> 390

tee doesn't forward the whole file but seems to stop when head don't read
anymore. I thought the -i flag was supposed to block such behavior?

I did this test with GNU coreutils 8.21 under fedora fc20. If you need more
info, just let me know.

Best,
Karl

This issue is already reported at http://bugs.gnu.org/11540
and I intend to deal with it through adding the tee --write-error=... option.
Shouldn't bee too hard.  I'll try and do it this weekend.

thanks,
Pádraig.
