 Name
      di - disk information

 Synopsis
      di [-AacghHklLmnPqRtZ] [-B block-size] [-d display-size] [-f format]
      [-I include-fstyp-list] [-s sort-type] [-w block-width] [-W

      [file [...]]

      mi

 Description
      di Displays usage information on mounted filesystems.  Block values
      are reported in a human readable format.  If the user or group has a
      disk quota, the values reported are adjusted according the quotas that
      apply to the user.

      If file is specified, the usage information for the partition on which
      file is located is printed.

      Unless the -a flag is specified, the following mounted filesystems
      will not normally be displayed: filesystems with total space <= 0;
      loopback filesystems that are duplicates of other normally mounted
      filesystems (filesystem type of 'lofs' , 'none', or 'nullfs');
      loopback filesystems that are part of a zone (Solaris).

      Filesystems that the user does not have permissions to access will not
      be displayed at all.

      mi Displays the mounted filesystem information.

      Several options may be specified to control the output of di and mi:

      -A   Print all fields (used for debugging).  Mount points and special
           device names are printed at full width.

      -a   (compatibility: --all)
           Prints all mounted devices (normally, those with 0 total space
           are not printed - e.g. /dev/proc, /dev/fd).

      -B   block-size (compatibility: --block-size, -b)
           Change the base block size from 1024 (default) to the size
           specified.  block-size may be one of: k - 1024 bytes, si - 1000
           bytes, or a specific size.

      -c   (alias: --csv-output)
           Comma separated values are output.  The titles are output as the
           format string specifiers.  Totals are turned off. See also the -n
           flag.

      -C   (alias: --csv-tabs)
           Values are output with tab separators.  See also the -c option.

      -d   display-size (alias: --display-size)
           Display the usage in units specified by display-size.  Note that
           if the base block size is SI units of 1000 bytes, the display
           size is calculated using those units.  display-size may be one
           of: 512 - POSIX, k - kilobytes, m - megabytes, g - gigabytes,
           t - terabytes, p - petabytes, e - exabytes, z - zettabytes,
           y - yottabytes, h - Scaled alternative 1, H - Scaled alternative
           2, or a specific value to use as the block size.

           Block display sizes greater than 1024 bytes are displayed with a
           precision of one decimal place after the radix.

           The Scaled alternatives scale the sizes displayed and appends a
           suffix (e.g. 48.0k, 3.4M).

           With scaled alternative 1, sizes within a line may scale to
           different units.

           Scaled alternative 2 scales all the sizes in each individual line
           to the same unit size (the largest needed).

      -f   format Use the specified format string format.  See the Format
           Strings section.

      -g   (alias for: -dg)
           Display sizes in gigabytes.

      -h   (alias for: -dh)
           Display partition sizes in scaled alternative 1 format.

      --help
           Display some basic usage information.

      -H   (alias for: -dH; compatibility: --human-readable)
           Display partition sizes in scaled alternative 2 format.

      -I   include-fstype-list (compatibility: -F, --type)
           Include only the file system types listed in include-fstyp-list.
           The list is a comma separated list of file system types.
           Multiple -I options may be specified.  If the 'fuse' filesystem
           type is specified, all fuse* filesystems will be included.
           e.g. -I nfs,tmpfs or -I nfs -I tmpfs.

      --inodes
           Ignored.  Use the -f option.

      -k   (alias for: -dk)
           Display sizes in Kbytes.

      -l   (compatibility: --local)
           Display only local file systems.

      -L   Turn off check for duplicate filesystems (loopback (lofs/none)
           mounts).

      -m   (alias for: -dm)
           Display sizes in megabytes.

      -n   Do not print a header line above the list of file systems.
           Useful when parsing the output of di.

      --no-sync
           Ignored.

      -P   (compatibility: --portability)
           Output format is POSIX standard.  512 byte block size is the
           default.  The -k option may be used.

      --print-type
           Ignored.  Use the -f option.

      -q   Disable quota checks.

      -R   (also: --dont-resolve-symlinks)
           Do not resolve symlinks (for mount points that have a trailing
           UUID).

      -s   sort-type
           Use sort-type to sort the output.  The output of di is normally
           sorted by mount point.  The following sort flags may be used to
           change the sort order: m - by mount point (default); n - leave
           unsorted (as it appears in the mount table); s - by special
           device name; T - by total space; f - by free space; a - by
           available space; t - by filesystem type; r - reverse the sort
           order; This will apply to all sort flags following this sort
           flag.

           These sort options may be combined in any order.  e.g.:
           di -stsrm # by type, special, reversed mount;
           di -strsrm # by type, reversed special, mount.

      --si An alias for -dH -Bsi.

      --sync
           Ignored.

      -t   (compatibility: --total)
           Print a totals line below the list of file systems.  Pooled
           filesystems (zfs, advfs) have only the main pool added to the
           total.  It is up to the user to exclude (using the -x option)

           read-only filesystems (cdfs, iso9660), swap-based (memfs, mfs,
           tmpfs) filesystems and user (fuse*) filesystems.  Excluding the
           'fuse' filesystem will exclude all fuse* filesystems.

      -w   block-width
           Set the print width for block values.  The default is eight.

      -v   Ignored.

      --version
           Display di's version and default format string.

      -W   inode-width
           Set the print width for inode values.  Default is seven.

      -x   exclude-fstype-list (compatibility: --exclude-type)
           Exclude the file system types listed in exclude-fstyp-list.  The
           list is a comma separated list of file system types.  Multiple -x
           options may be specified.  If the 'fuse' filesystem type is
           excluded, all fuse* filesystems will be excluded.  e.g. -x
           nfs,tmpfs or -x nfs -x tmpfs.

      -X   level
           Set the program's debugging level to debug-level.

      -z   zone-name
           Display the filesystems for the specified zone.  The zone must be
           visible to the user.

      -Z   (alias for: -z all)
           Display the filesystems for all visible zones.

 Format Strings
      The output of di may be specified via a format string.  This string
      may be given either via the -f command line option or as part of the
      DI_ARGS environment variable.  The format string may specify the
      following columns:

      m    Print the name of the mount point.

      M    Print the name of the mount point, at full length.  The mount
           point is formatted to the maximum width necessary for the longest
           mount point name.

      s    Print the file system name (special device or remote mount
           point).

      S    Print the file system name (special device or remote mount
           point), at full length.  The file system name is formatted to the
           maximum width necessary for the longest file system name.

           supported on all systems.

      O    Print the filesystem mount options.

      The default format string for di is smbuvpT.

      The default format string for mi is MSTIO.

      The format string may also contain any other character not listed
      above.  The character will be printed as is.  e.g. di -f 'mbuvp|iUFP'
      will print the character '|' between the disk usage and the file slot
      usage.  The command sequence:
           di -f 'mbuvp
           miUFP'
      will print two lines of data for each filesystem.

 Examples
      Various df equivalent format strings for System V release 4 are:
           /usr/bin/df -v     di -P -f msbuf1
           /usr/bin/df -k     di -dk -f sbcvpm
           /usr/ucb/df        di -dk -f sbuv2m
      GNU df:
           df                 di -dk -f SbuvpM -w 10
           df -T              di -dk -f STbuvpM -w 10
      AIX df:
           df                 di -d 512 -f Sbf1UPM -w 10
           df -I              di -d 512 -f Sbuf1M
           df -I -M           di -d 512 -f SMbuf1 -w 10
      HP-UX bdf:
           bdf                di -d k -f Sbuv2M
           bdf -i             di -d k -f Sbuv2UFPM

      If you like your numbers to add up/calculate the percentage correctly,
      try one of the following format strings:

           di -f SMbuf1T
           di -f SMbcvpT
           di -f SMBuv2T

 Environment Variables
      The DI_ARGS environment variable may be used to specify command line
      arguments.  e.g. If you always want gigabytes displayed, set DI_ARGS
      equal to "-dg".  Any command line arguments specified will override
      the DI_ARGS environment variable.

      The DI_LOCALE_DIR environment variable may be used to specify the
      location of the di program's locale message files.

      The GNU df POSIXLY_CORRECT, and DF_BLOCK_SIZE and the BSD BLOCKSIZE
      environment variables are honored.

 Note
      For filesystems that do not report available space (e.g. System V
      release 3), the number of available space is set to the free space.

 WARNING
      Do not replace your system's df command with this program.  You will
      in all likelihood break your installation procedures.
