tail -f
I am trying to extract a particular line from a.log which keeps appending every sec and output that into a newfile b.log which should append itself with filtered data received from a.log
I tried
tail -f a.log |grep fail| tee -a b.log
nothing in b.log
tail -f a.log |grep fail >>b.log
nothin shows up in b.log
what am i missing?
Is there an option similar to tail -f with awk?
