DF(1)                                                       DF(1)



     NAME
          df - report number of free disk blocks

     SYNOPSIS
          df [ -f ] [ -i ] [ file-systems ]

     DESCRIPTION
          df reports the number of free disk blocks (1 disk block
          equals 1 kbyte) available for on-line file systems.  The
          file-systems argument may be specified either by a device
          name (e.g., /dev/md0c) or by a mounted directory name (e.g.,
          /usr).  If the file-systems argument is unspecified, df
          reports on all file systems listed in the file /etc/fstab.

          Normally, the free block information is gleaned from the
          file system's superblock.  The -f flag forces a scan of the
          free block list.

          The -i flag reports the number and percentage of free
          inodes.

     FILES
          /etc/fstab
          /etc/mtab

     SEE ALSO
          statfs(2), fs(4), mntent(4).

     BUGS
          Free counts may be incorrect, with or without the -f flag.
