normally tail -f shows 10-15 already logged content.How can I avoid it? I only want to see newly logged content.Is there any switch in tail for that.Please advice.
Simply set to return zero lines:
tail -n 0 -f /var/log/syslog
-n, --lines=K output the last K lines, instead of the last 10; or use -n +K to output lines starting with the Kth
