Shell Programming and Scripting

Is it possible to sent a ^C interrupt via the command line? For example if I want to tail a log for 10 minutes at a time, kill the tail and then start it again is there a way to go about that? I would imagine there would be some way to do it by finding and killing the PID, but I'm curious if there's another way.

All I want is to be able to do a one liner like:

Code:

while true;do tail -f n2bb.log|grep 0x12|nl;sleep 600;<whatever kills the tail>;done

Maybe something like:
_kill() { sleep 10m; pkill -9 -f 'tail -f /path/to/n2bb.log'; }; _tail() { _kill & \
tail -f /path/to/n2bb.log|grep 0x12|nl; _tail; }; _tail
May look odd but still is a oneliner.

Hmmm, I'll have to take a look into something like that. Not sure if thats the directiion want to go with this...but as there don't seem to be a lot of options at the moment...
