Then you may choose the file to open. If there's only one match, the file will be opened directly.
Found is deadly simple. First, it joins all the terms from the command line into a locate query, e.g.:
$ found lamport pdf
turns into:
$ locate -b -i "*lamport*pdf*"
After you specified the file to open, found will call xdg-open to open the file with the most appropriate program.
