With a linux background I'm used to being able to my the system logger right to a named pipe buy means of a `|' (pipe) symbol in syslog.conf
*.* |/var/log/fifo But on Opensolaris the system logger is enough different than the sysklogd daemon on linux that the `|' symbol is ignored in /etc/syslog.conf On opensolaris, you can tell syslogger to write direct to the fifo. But it has a side effect Lets say you create the fifo To get data flowing into your filter or script, syslog needs a restart. But first we use the easy example of cat. cat fifo Now restart system logger. Now anything that sys logger produces will be displayed from the cat command. Now restart systemlogger again and cat closes as would a common shell script or awk. However the `tail -f' command will not close... it keeps on reading through restarts. I want to get that behavior from a perl script. I realize I could have my script read from `tail -f fifo|script.pl' but that introduces another factor... a buffer filling factor where tail -f's shell buffer has to fill up between writes. That introduces a lag... so if you want a truly live syslog read.. you need some kind of fancy buffer flushing or the like. I'm not sure what it is about the tail -f command that allows it to keep reading over restarts of system logger (on Opensolaris)... but how can I emulate whatever it is.. in perl? -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
