>Description:
	In the very beggining of tcpdump(1) it is said:

       Tcpdump  prints  out the headers of packets on a network interface that
       match the boolean expression.  It can also be run  with  the  -w  flag,
       which  causes  it to save the packet data to a file for later analysis,
       and/or with the -b flag, which causes it to read from  a  saved  packet
       file  rather  than  to  read  packets from a network interface.  In all
       cases, only packets that match expression will be processed by tcpdump.

	Really packet dumps can be read with -r flag. 

>How-To-Repeat:
	man 1 tcpdump
