di - disk information
Synopsis
di [-AaghHklLmnPtZ] [-b block-size] [-d display-size] [-f
format] [-I include-fstyp-list] [-s sort-type] [-w
block-width] [-W inode-width] [-x exclude-fstyp-list] [-X
debug-level] [-z zone-name] [file [...]]
mi
Description
di Displays usage information on mounted filesystems. Block
values are reported in megabytes (1024k bytes) by default,
but may be changed. If file is specified, the usage infor-
mation 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 blocks <= 0; filesystems marked by the operating sys-
tem as "ignore"; automounted filesystems that are duplicates
of other normally mounted filesystems; loopback filesystems
that are part of a zone (Solaris).
mi Displays the mounted filesystem information.
Several switches 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.
The -a flag is set.
-a Prints all mounted devices (normally, those with 0
total blocks are not printed - e.g. /dev/proc,
/dev/fd).
-b block-size (compatibility: -B)
Change the base block size from 1024 (default) to the
size specified. block-size may be one of: k - 1024
bytes, d - 1000 bytes, or a specific size.
-d display-size Display the blocks in units specified by
display-size. 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 indi-
vidual line to the same unit size (the largest needed).
-f format Use the specified format string format. Format
strings are described below.
-g (alias for: -dg)
Display sizes in gigabytes.
-h (alias for: -dh)
Display partition sizes in scaled alternative 1 format.
-H (alias for: -dH)
Display partition sizes in scaled alternative 2 format.
-I include-fstype-list (compatibility: -F)
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. e.g. -I nfs,rfs or -I nfs -I rfs.
-k (alias for: -dk)
Display sizes in Kbytes.
-l Display only local file systems.
-L Don't do the check for duplicate filesystems.
-m (alias for: -dm)
Display sizes in megabytes.
-n Do not print a header line above the list of file sys-
tems. Useful when parsing the output of di.
-P Output format is POSIX standard. 512 byte block size
is the default. The -k option may be used.
-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 filesystem type; r - reverse the sort
order.
These sort options may be combined in any order. e.g.:
di -stsrm; di -strsrm.
-t Print a totals line below the list of file systems.
Memory filesystems (tmpfs, mfs) and read-only filesys-
tems are not added to the totals.
-w block-width
Set the print width for block values. Default is
eight.
-W inode-width
Set the print width for inode values. Default is
seven.
-x exclude-fstype-list (old: -i)
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. e.g. -x nfs,rfs or -x nfs -x rfs.
-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 switch or
by the DIFMT 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.
b Print the total number of megabytes on the file system.
See also the -d option.
B Print the total number of megabytes on the file system
available for use by normal users. See also the -d
option.
u Print the number of megabytes in use on the file system
(actual number of megabytes used = total - free). See
also the -d option.
c Print the number of megabytes not available for use by
normal users (total - available). See also the -d
option.
f Print the number of free (unused) megabytes on the file
system. See also the -d option.
v Print the number of megabytes available for use by nor-
mal users. See also the -d option.
p Print the percentage of megabytes not available for use
by normal users (number of megabytes not available for
use / total disk space). See also the -d option.
1 Print the percentage of total megabytes in use (actual
number of megabytes used / total disk space). See also
the -d option.
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). See also the -d option.
a Print the percentage of megabytes available for use by
normal users (number of megabytes available for use /
total disk space). See also the -d option.
3 Print the percentage of total megabytes free (actual
number of megabytes free / total disk space). See also
the -d option.
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.
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 long-
est 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.
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
(Bourne Shell):
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
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 DIFMT environment variable may be used to specify the
default display format string.
The DI_ARGS environment variable may be used to specify com-
mand 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 GNU df POSIXLY_CORRECT, and DF_BLOCK_SIZE and the BSD
BLOCKSIZE environment variables are honored.
Note
For filesystems that do not report available blocks (e.g.
System V release 3), the number of available blocks is con-
sidered to be the number of free blocks.
WARNING
Do not replace your system's df command with this program.
You will in all likelihood break your installation pro-
cedures.

Nice program.
Cool program.
Nice package.
I just grabbed di from news and it looks great, ... Thanks for starting what will be one of the great sysadmin tools
Thanks for a great tool!
If I may add my $.02 to your efforts (which I find rather exceptional, IMHO)...
BTW, nice program. Thanks for writing it.
Thank you thank you thank you for the code,... Again, many thanks for posting the code.
Great Utility! I love being able to specify the format of the output via commandline. Again, thanks for a great toy!
Many thanks for your efforts!!
Thanks very much for your efforts on di.
First of all you wrote an excellent utility....
It's great to have a Sun-like df again. Thanks!
(By the way, I stopped using 'df', since I installed 'di'. I like it.)
'di' looks nice and will see much use here at 'liedus'.
Thanks for a new tool. ... Thanks again for a nifty file,
Thanks for this neat tool,
Great tool!
Thanks for maintaining diskinfo! I find it *very* useful since I administer many different platforms.
Thanks for the di command. It looks really useful.... Thanks again for the very useful program.
Neat program, compiled first time, no errors, and it works great.
Hi! I use your "di" program. It is great! Now I can have consistent reports of disk usage no matter what platform I am on. I use it on HP-UX, SunOS, IRIX, Ultrix, so far. Thanks a lot.
Great tool. We find it far more functional than even GNU df. Keep up the good work..
