While I was reading Tethereal manual about using the option "-l ",I was confused.

In the part of options using "-l",it says that  :

This may be useful when piping the output of Tethereal to another program, as it means that the program to which the output is piped will see the dissected data for a packet as soon as Tethereal sees the packet and generates that output, rather than seeing it only when the standard output buffer containing that data fills up.

My question is that how to use the option "-l" to pipe the output of Tethereal to another program.

Anybody can  give me an  example?
