Contained If no file system is specified, the free space on all of NOTE: 1Gb = 1000 000kb the normally mounted file systems is printed. The reported numbers are in kilobytes. Options Options # The bdf command recognizes the following options: bdf command has the following options: -b Display information regarding file system -b demonstrate the exchange of information about the file system swapping.

Non-HFS file systems may have other items not accounted for by this command. AUTHOR bdf was developed by the University of California, Berkeley.
