For the record, linux doesn't have a Trash/Recycle Bin in the sense that Windows does. That folder is (for GNOME at least), a psuedo-trash folder, it's a perfectly normal directory and requires no special commands to play with
Now to the problem, copying it back should fix the problem. Is the dir structure /root/.Trash/etc/init.d? If so, this *should* work...
cp /root/.Trash/etc/* /etc/
