Yes. If you can see the generated commands you can then look up the options that you don't recognize.

(I omitted the options for simplicity.) The script creates a new filename replacing ".mkv" with ".avi" and runs mencoder to create the file. It iterates over all files in the current directory matching *.mkv. I enclosed the filenames in quotes in case they have embedded spaces.
for f in *.mkv
NEWNAME=$(echo $f | sed 's/\.mkv$/.avi/g')
mencoder "$f" -o "$NEWNAME" -ovc xvid -oac mp3lame
One other GUI tool you might look at is Handbrake.
