The set of things you can get Ethereal to do from the command line is
limited.  If you want to do that from the command line, you'd use
Tethereal without the "-w" option and:

    with the "-V" option if you want the details of the packet rather than
the summary;

    with the "-x" option if you also want a hex dump of the packet data.

Use the "-r" option to read from a capture file; if you don't use "-r", it
does a live capture, in which case you use the "-i" flag to specify an
interface if you aren't going to be capturing from the default interface. 
See the Tethereal man page for full details on the command-line options.
