.Sh NAME
.Nm df
.Nd display free disk space
.Sh SYNOPSIS
.Nm
.Op Fl b | g | H | h | k | m | P
.Op Fl acilnT
.Op Fl t Ar type
.Op Ar file | filesystem ...
.Sh DESCRIPTION
The
.Nm
utility
displays statistics about the amount of free disk space on the specified
.Ar file system
or on the file system of which
.Ar file
is a part.
Values are displayed in 512-byte per block counts.
If neither a file or a file system operand is specified,
statistics for all mounted file systems are displayed
(subject to the
.Fl t
option below).
.Pp
The following options are available:
.Bl -tag -width indent
.It Fl a
Show all mount points, including those that were mounted with the
.Dv MNT_IGNORE
flag.
.It Fl b
Use 512-byte blocks rather than the default.
Note that
this overrides the
.Ev BLOCKSIZE
specification from the environment.
.It Fl c
Display a grand total.
.It Fl g
Use 1073741824-byte (1-Gbyte) blocks rather than the default.
Note that
this overrides the
.Ev BLOCKSIZE
specification from the environment.
.It Fl H
.Dq Human-readable
output.
Use unit suffixes: Byte, Kilobyte, Megabyte,
Gigabyte, Terabyte and Petabyte in order to reduce the number of
digits to four or fewer using base 10 for sizes.
.It Fl h
.Dq Human-readable
output.
Use unit suffixes: Byte, Kilobyte, Megabyte,
Gigabyte, Terabyte and Petabyte in order to reduce the number of
digits to four or fewer using base 2 for sizes.
Inodes statistics, if enabled with
.Fl i ,
are always printed in base 10.
.It Fl i
Include statistics on the number of free inodes.
.It Fl k
Use 1024-byte (1-Kbyte) blocks rather than the default.
Note that
this overrides the
.Ev BLOCKSIZE
specification from the environment.
.It Fl l
Only display information about locally-mounted file systems.
.It Fl m
Use 1048576-byte (1-Mbyte) blocks rather than the default.
Note that
this overrides the
.Ev BLOCKSIZE
specification from the environment.
.It Fl n
Print out the previously obtained statistics from the file systems.
This option should be used if it is possible that one or more
file systems are in a state such that they will not be able to provide
statistics without a long delay.
When this option is specified,
.Nm
will not request new statistics from the file systems, but will respond
with the possibly stale statistics that were previously obtained.
.It Fl P
Use POSIX compliant output of 512-byte blocks rather than the default.
Note that this overrides the
.Ev BLOCKSIZE
specification from the environment.
.It Fl t
Only print out statistics for file systems of the specified types.
More than one type may be specified in a comma separated list.
The list of file system types can be prefixed with
.Dq no
to specify the file system types for which action should
.Em not
be taken.
For example, the
.Nm
command:
.Bd -literal -offset indent
df -t nonfs,nullfs
.Ed
.Pp
lists all file systems except those of type
.Tn NFS
and
.Tn NULLFS .
The
.Xr lsvfs 1
command can be used to find out the types of file systems
that are available on the system.
.It Fl T
Include file system type.
.El
.Sh ENVIRONMENT
.Bl -tag -width BLOCKSIZE
.It Ev BLOCKSIZE
If the environment variable
.Ev BLOCKSIZE
is set, the block counts will be displayed in units of that size block.
.El

.Xr mount 8 ,
.Xr quot 8
.Sh HISTORY
A
.Nm
command appeared in
.At v1 .
.Sh BUGS
The
.Fl n
flag is ignored if a file or file system is specified.
Also, if a mount
point is not accessible by the user, it is possible that the file system
information could be stale.

Most modern OSs have the ability to flag certain mounts as ones to be ignored by default by the df(1) program. This is used mostly to avoid stat()-ing entries that do not represent "real" disk mount points (such as those made by an automounter such as amd.) It is also useful not to have to stat() these entries because it takes longer to report them that for other file systems, being that these mount points are served by a user-level file server and resulting in several context switches. Worse, if the automounter is down unexpectedly, a causal df(1) will hang in an interruptible way. PR: kern/9764 Submitted by: Erez Zadok <ezk@cs.columbia.edu> 1999-11-01 04:57:43 +00:00			`.It Fl a`
