hi i am new to unix,i want a command that will sleep for 10sec and show last 100 line

i want a command that will sleep for 10sec and show last 100 lines in unix log file

i am using

tail -f -s10 -n100 filename (this command showing 100 lines only once, but as the file is appending i am unable to view the next 100 lines)

Plz guide me...

i too was not able to do it with that command, so, here is my script

$ for i in `seq 1 100`;do tail -n100 filename ;sleep 10; done;

Here the problem is the loop is not infinite, but i think large value can make it . :)
