data for each packet.

-S

This option specifies that Ethereal will display packets as it
captures them. This is done by capturing in one process and
displaying them in a separate process. This is the same as "Up-
date list of packets in real time" in the Capture Options dialog
box.

-t <time stamp format>

This option sets the format of packet timestamps that are dis-
played in the packet list window. The format can be one of:

r relative, which specifies timestamps are displayed relat-
ive to the first packet captured.

a absolute, which specifies that actual times be displayed
for all packets.

ad absolute with date, which specifies that actual dates
and times be displayed for all packets.

d delta, which specifies that timestamps are relative to the
previous packet.

-v

The -v option requests Ethereal to print out its version in-
formation and exit.

-w <savefile>

This option sets the name of the savefile to be used when sav-
ing a capture file.

-y <capture link type>

If a capture is started from the command line with -k, set the
data link type to use while capturing packets. The values re-
ported by -L are the values that can be used.

-z <statistics-string>

Get Ethereal to collect various types of statistics and display
the result in a window that updates in semi-real time. XXX -
add more details here!
