NAME
df - Reports the number of free disk blocks and inodes
SYNOPSIS
df [-l] [-t] [-f] [file-system|directory|mounted-resource]
FLAGS
-l Reports on local file systems.
-t Causes the figures for total allocated blocks and inodes to be
reported along with the free blocks and inodes.
-f Produces an actual count of the blocks in the free list, rather than
taking the figure from the superblock (free inodes are not reported).
This flag will not display any information about mounted remote
resources. This flag only works with S51K file systems or on
unmounted Fast File Systems (ffs).
DESCRIPTION
The df command displays the number of free disk blocks and free inodes in
mounted file systems, directories, or mounted resources by examining the
counts kept in the superblocks.
File-system may be specified either by a device name (for example,
/dev/dsk/s0u0p7.3) or by a mount point directory name (for example, /usr).
Directory can be a directory name. The report presents information for
the device that contains the directory.
Mounted-resource can be a remote resource name. The report presents
information for the remote device that contains the resource.
The device or mounted file system can be an fs type file system, in which
case df displays the information. If the device is unmounted and is not
an fs type file system, then df executes the fstyp command, forms a
pathname from the output, and executes the program so formed. For
example, if fstyp reports the file system to be of type ``FFS'', df will
execute ffsdf.
If no arguments are used, the free space on all locally and remotely
mounted file systems is displayed.
EXAMPLES
The following reports the free inodes and disk blocks on the /usr file
system:

FILES
/dev/dsk/*
/etc/mnttab
NOTES
If multiple remote resources are listed that reside on the same file
system on a remote machine, each listing after the first one will be
marked with an asterisk.
CAUTIONS
Problems may occur if a file system or directory whose complete pathname
is longer than 32 characters is not mounted using /etc/fstab.
EXIT VALUES
If unsuccessful, df returns a nonzero exit value.
