df(1-ufs)                                                         df(1-ufs)

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

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

DESCRIPTION
     The df command reports the number of free disk blocks and inodes for a
     ufs file system.

     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 sys-
     tem 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
     the super-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.

OPTIONS
     -F ufs              Specifies the ufs-FSType.

     genericoptions     Options supported by the generic df command.

     -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 the options -b, -e, -k,
                              -t, -v, -g, -l, -n of the generic df command.

LOCALE
     The LCMESSAGES environment variable governs the language in which
     message texts are displayed.

     If LCMESSAGES is undefined or is defined as the null string, it
     defaults to the value of LANG. If LANG is likewise undefined or null,
     the system acts as if it were not internationalized.

     If any of the locale variables has an invalid value, the system acts
     as if none of the variables were set.

     The LCALL environment variable governs the entire locale. LCALL
     takes precedence over all the other environment variables which affect
     internationalization.

FILES
     /dev/ios*/*disk*

     /etc/mnttab
          list of file systems currently mounted
