The first thing you want to put on the command line is the letter "t" 
immediately before "ethereal". :-)

I.e., you would do that with Tethereal, not with Ethereal.

I assume you mean "translate file.in to a text file with protocols 
decoded", not 'translate file.out".  If so, you would do

	tethereal -V -r file.in >file.out

which will read "file.in" and write to its standard output - which is 
redirected to "file.out" with ">file.out" - a compleete dissection of 
all the packets in "file.in".
