Anyone that knows how to emty logs.
I have tried this Workaround
But didn't help me out jus 5gb free

Create a script that will remove logs over 7 days old. /etc/cron.daily
3.Press 'i' to enter insert mode, and type:
find /var/opt/novell/tomcat-filr/logs/* -type f -mtime +7 -exec rm {} \;
4.Press 'Esc' and type ":wq!" without the quotes to save and quit
5.Type chmod +x

So is there a way to empty the logs manually?
