find files by name
 
-c, --count
       Instead of writing file names on standard output, write the number of matching entries only.
 
-d, --database DBPATH
       Replace  the  default  database with DBPATH.  DBPATH is a :-separated list of database file names.
       If more than one --database option is specified, the resulting path  is  a  concatenation  of  the
       separate paths.

       An empty database file name is replaced by the default database.  A database file name - refers to
       the standard input.  Note that a database can be read from the standard input only once.
