hmmm.. if 'tail -f filename' continuously outputs using stdout, how could
I stop it when the text I'm looking for appears?  I want tail to terminate
when it receives the following information: 

	caller=##########, conn='', name='username'

..and put those strings in variables for another program to use.

tail -f /var/log/mgetty/mg_ttyS1.log | (
