[opensuse] Syntax forc combining tailf and grep
I am viewing the /var/log/messages file and as there are alot of entries in it and it is constantly being updated, I wondered if there was a way to display an updating grep on the file without having to create a script and corresponding cron entry to run every time the file is updated ie #tailf /var/log/messages|grep backup Just wondering if its possible. -- ======================================================================== Using SuSE 9.2 Professional with KDE and Mozilla Mail 1.7.13 Linux user # 229959 at http://counter.li.org ======================================================================== -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Of course it works. Did you try? :-) Also, you can taylor syslog-ng to create a separate log file filtered with what you want in it. - -- Cheers, Carlos E.

:( No I didn't :( On a grep cmd of the /var/log/messages file I saw there were many entries that came back. I thought that with the above command incorporating tailf that I would get the last 10 or so entries. When the cmd gave me nothing, without backung up, I prefered to err on the side of caution, and ask here first. I have now executed the command and initiated a backup and I am getting the display I wanted, bit not what I thought I would get.

Another time far far away....:) -- ======================================================================== Using SuSE 9.2 Professional with KDE and Mozilla Mail 1.7.13 Linux user # 229959 at http://counter.li.org ======================================================================== -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

SuSE uses just such a filter to create the separate firewall log and exclude firewall entries from /var/log/messages. So, when you do wish to try this, you have an excellent working example already. Make changes to file /etc/syslog-ng/syslog-ng.conf.in, and run "SuSEconfig --module syslog-ng" when you are done.
