Hi,

I want to use tail and grep to follow a file until a particular pattern 
appears. But tail does not exit when grep is finished.

$ echo xxx > /tmp/blabla
$ tail -f /tmp/blabla |grep -m1 --line-buffered "xxx"
xxx

Now tail still tries to read and exits only if I write again 
into /tmp/blabla.

Is this how it's supposed to be?

cu,
Rudi
