Hi,
It seems bsdgrep does not work when piped from tail -f.
I'm running r210728.
term0$ jot 10> /tmp/1
term0$ tail -f /tmp/1 | grep 0
[no output]
otherterm$ jot 10>> /tmp/1
[no output to term0]
=====
with GNU grep:
term0$ tail -f /tmp/1 | gnugrep 0
10
otherterm$ jot 10>> /tmp/1
[on term0]
10
10
I've checked on 8.0 and GNU grep doesn't output anything either for me.
If you use tail -f, you will enter more lines and end it with EOF, won't
you? And then BSD grep will process the input and print out matches. I
don't think it's bad behaviour in itself but if you can explain why you
think it's bad I'm willing to change it.
Thanks for your comment,
Gabor
