df(1M_UFS)                     (UFS)                      df(1M_UFS)


       NAME
             df (ufs) - report free disk space on ufs file systems

       SYNOPSIS
             df [-F ufs] [generic_options] [-o i] [directory | special]

       DESCRIPTION
             generic_options are options supported by the generic df
             command.

             df displays the amount of disk space occupied by ufs file
             systems, the amount of used and available space, and how much
             of the file system's total capacity has been used.

             Note that the amount of space reported as used and available
             is less than the amount of space in the file system; this is
             because the system reserves a fraction of the space in the
             file system to allow its file system allocation routines to
             work well.  The amount reserved is typically about 10%; this
             may be adjusted using tunefs(1M).  When all the space on the
             file system except for this reserve is in use, only a
             privileged user can allocate new files and data blocks to
             existing files.  When the file system is overallocated in this
             way, df may report that the file system is more than 100%
             utilized.

             The options are:

             -F ufs
                   Specifies the ufs-FSType.

             -o    Specify ufs file system specific options.  The available
                   option is:

                   i     Report the number of used and free inodes.  May
                         not be used with generic_options.

       NOTICES
             df calculates its results differently for mounted and
             unmounted file systems.  For mounted systems the 10% reserved
             space mentioned above is included in the number of blocks
             used.  For unmounted systems the 10% reservation is not
             included in the number of blocks used. The generic -k option
             displays the free space as a percentage.
