Yes it does... but like you said... it leaves a problem for the
script. My coding skills are quite slim. I see a command like
`tail -f named-pipe'
Will keep reading so any ouput from system logger is displayed... but
a regular kind of command like:
cat named-pipe
cat will close after the first line is read.
Similar for something like awk '/REGEX/{print}' named-pipe > some.log
awk will close after the first line of input.
I guess I need to write a script that behaves like `tail -f' and I'm
sure I can in perl, but is that really necessary?
Isn't there some way to get a standard filtering script to get all
lines the system logger puts out, without trickery inside the script
to keep it from closing after the first line.
I guess the linux way of using a pipe `|' in the actual syslog.conf is
one way to get it done... but that does not work on opensol.
