Hi, yes the best thing is to use featquery. As long as you're not
using windows, when you press GO on featquery, it tells you the
command-line call it made - then you can easily work out how to call
it yourself from the command line. If you're using windows, shame on
you, but you can still get the syntax by just typing "featquery" in
the terminal.
Cheers, Steve.
