  -c, --count            only print number of found entries
  -d, --database DBPATH  use DBPATH instead of default database (which is
                         /var/lib/mlocate/mlocate.db)
  -e, --existing         only print entries for currently existing files
  -L, --follow           follow trailing symbolic links when checking file

  -h, --help             print this help
  -i, --ignore-case      ignore case distinctions when matching patterns
  -p, --ignore-spaces    ignore punctuation and spaces when matching patterns
  -t, --transliterate    ignore accents using iconv transliteration when
                         matching patterns
  -l, --limit, -n LIMIT  limit output (or counting) to LIMIT entries

  -0, --null             separate entries with NUL on output
  -S, --statistics       don't search for entries, print statistics about each

  -q, --quiet            report no error messages about reading databases
  -r, --regexp REGEXP    search for basic regexp REGEXP instead of patterns
