df Command

The df command has been changed to support the VFS architecture. As with the other VFS commands, there are generic and file-system versions of the command. The syntax in the SunOS release 5.7 command differs significantly from that used in the SunOS release 4.x version (see Appendix A, Commands Reference Table, for more information). For more information on VFS, see "Virtual File System Architecture".

The df command now reports disk space in 512-byte blocks instead of kilobytes, but the -k option can be used to report disk space in kilobytes. Also, the -t option behaves differently; formerly, it restricted the output to file systems of a specified type (for example, "nfs" or "4.2"). The SunOS release 5.7 version produces a full listing with totals.

Finally, use the SunOS release 5.7 device naming conventions when specifying special device names to this command. See "Device Naming Conventions" for details.
