Synopsis

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

       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.

       t      Print the file system type.

       T      Print the file system type at full length.  The file system type  is  formatted  to
              the maximum width necessary for the longest file system type.

       Total Available

       b      Print the total number of megabytes on the file system.

       B      Print  the total number of megabytes on the file system available for use by normal
              users.

       In Use

       u      Print the number of megabytes in use on the file system (actual number of megabytes
              used = total - free).

       c      Print  the  number  of  megabytes  not  available  for use by normal users (total -
              available).

       Free

       f      Print the number of free (unused) megabytes on the file system.

       v      Print the number of megabytes available for use by normal users.

       Percentage Used

       p      Print the percentage of megabytes not available for use by normal users (number  of
              megabytes not available for use / total disk space).

       1      Print  the  percentage of total megabytes in use (actual number of megabytes used /
              total disk space).

       2      Print the percentage of megabytes in use, BSD-style.  Represents the percentage  of
              user-available  space  in  use.   Note  that  values over 100% are possible (actual
              number of megabytes used / disk space available to non-root users).

       Percentage Free

       a      Print the percentage of megabytes available for use  by  normal  users  (number  of
              megabytes available for use / total disk space).

       3      Print  the  percentage  of  total megabytes free (actual number of megabytes free /
              total disk space).

       Inodes

       i      Print the total number of file slots (inodes) that  can  be  created  on  the  file
              system.

       U      Print the number of file slots in use.

       F      Print the number of file slots available.

       P      Print the percentage of file slots in use.

       Mount Information

       I      Print  the  time  the  filesystem was mounted.  This column is not 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.

       Known Issues:

       di  will  probably  not  process a zettabyte or yottabyte sized filesystem properly due to
       overflow of a long long.
