uadf

NAME

  uadf - summarize free	disk space

SYNOPSIS

  uadf [-aikPv]	[-t fstype] [-x	fstype]	[--all]	[--inodes] [--type=fstype]
       [--exclude-type=fstype] [--kilobytes] [--portability] [--print-type]
       [--help]	[--version] [filename...]

DESCRIPTION

  This manual page documents the University of Alaska uadf variant of the GNU
  version of df.  uadf displays	the amount of disk space available on the
  filesystem containing	each file name argument. If no file name is given,
  the space available on all currently mounted filesystems is shown. Disk
  space	is shown in 1K blocks by default, unless the environment variable
  POSIXLY_CORRECT is set, in which case	512-byte blocks	are used.

  If an	argument is the	absolute file name of a	disk device node containing a
  mounted filesystem, df shows the space available on that filesystem rather
  than on the filesystem containing the	device node (which is always the root
  filesystem). This version of uadf cannot show	the space available on
  unmounted filesystems, because on most kinds of systems doing	so requires
  very nonportable intimate knowledge of filesystem structures.

OPTIONS

  -a | --all
       Include in the listing filesystems that have 0 blocks, which are	omit-
       ted by default. Such filesystems	are typically special-purpose
       pseudo-filesystems, such	as automounter entries.	On some	systems,
       filesystems of type ``ignore'' or ``auto'' are also omitted by default
       and included in the listing by this option.

  -i | --inodes
       List inode usage	information instead of block usage.  An	inode (short
       for ``index node'') is a	special	kind of	disk block that	contains
       information about a file, such as its owner, permissions, timestamps,
       and location on the disk.

  -k | --kilobytes
       Print sizes in 1K blocks	instead	of 512-byte blocks.  This overrides
       the environment variable	POSIXLY_CORRECT.

  -P | --portability
       Use the POSIX output format.  This is like the default format except
       that the	information about each filesystem is always printed on
       exactly one line; a mount device	is never put on	a line by itself.
       This means that if the mount device name	is more	than 20	characters
       long (as	for some network mounts), the columns are misaligned.

  -T | --print-type
       Print a type string for each filesystem.	 Any such printed filesystem
       type name may be	used as	an argument to either of the --type= or
       --exclude-type= options.

  -t | --type=fstype
       Limit the listing to filesystems	of type	fstype.	 Multiple filesystem
       types can be shown by giving multiple -t	options.  By default, all
       filesystem types	are listed.

  -x | --exclude-type=fstype
       Limit the listing to filesystems	not of type fstype.  Multiple
       filesystem types	can be eliminated by giving multiple -x	options.  By
       default,	all filesystem types are listed.

  -v   Ignored;	for compatibility with System V	versions of df.

  --help
       Print a usage message on	standard output	and exit successfully.

  --version
       Print version information on standard output then exit successfully.
