Try this instead:
for f in *.vob ; do
mplayer -ao pcm:file=${f%.vob}.wav $f
done
Uses the shell's native file globbing to expand the *.vob wildcard, and the
shell's native string processing functions to remove a suffix. If that
still doesn't work, run the script with "sh -x" to turn debugging on, and
see what your variables are expanding to as the script runs.
