the -w option specifies the name of a *capture file* in which to save
the filtered output. So what you are doing is to create a filtered
capture file that can be opened with (at least) ethereal.

If you want to save the TEXT output of tethereal you want to call it as

$ tethereal.exe -i 2 -f "tcp port 3128" -R http.request.method=="GET" 
-c 20 -V > capture.txt

that way the text output gets redirected to capture.txt . Note that I
added the -V option so that the dissection tree appears in the file If
you want just the summary you can supress it.
