.TH DF 1 "04 August 1997" GNO "Commands and Applications"
|
||||
.SH NAME
|
||||
.BR df
|
||||
\- display free disk space and disk usage statistics
|
||||
.SH SYNOPSIS
|
||||
.BR df " [" -k "] [" -t
|
||||
.IR "FST list"
|
||||
]
|
||||
.IR devnum
|
||||
|
|
||||
.IR vol
|
||||
|
|
||||
.IR file ...
|
||||
.SH DESCRIPTION
|
||||
displays statistics about the amount of free disk space on the
|
||||
specified device number
|
||||
.IR devnum
|
||||
(.d##), on the specified volume
|
||||
.IR vol
|
||||
or on the volume of which
|
||||
.IR file
|
||||
is a part. More than one device number, volume, or file may be
|
||||
listed, and types can be mixed in the argument list.
|
||||
.LP
|
||||
Values are displayed in 512-byte per block block counts.
|
||||
If neither a file or a filesystem operand is specified,
|
||||
statistics for all mounted filesystems are displayed.
|
||||
Devices without valid media (e.g. a 3.5" disk drive with
|
||||
no disk in the drive) are not included in the output.
|
||||
.SH OPTIONS
|
||||
The following options are available:
|
||||
.IP \fB-k\fR
|
||||
Use 1024-byte (1-Kbyte) blocks rather than the default. Note
|
||||
that this overrides the
|
||||
.BR BLOCKSIZE
|
||||
specification from the environment.
|
||||
.IP "\fB-t\fR \fIfst1,...,fstN\fR"
|
||||
Only print out statistics for filesystems of the specified types.
|
||||
More than one type may be specified in a comma separated list.
|
||||
The list of filesystem types can be prefixed with
|
||||
.IR no
|
||||
to specify the filesystem types for which action should
|
||||
not be taken.
|
||||
.LP
|
||||
For example, the
|
||||
.BR df
|
||||
command:
|
||||
.nf
|
||||
df -t nohfs,msdos
|
||||
.fi
|
||||
lists all filesystems except those of type
|
||||
.IR HFS
|
||||
and
|
||||
.IR MS-DOS
|
||||
.LP
|
||||
Acceptable filesystem types are as follows:
|
||||
.IP
|
||||
prodos, dos33, dos32, pascal, mfs, hfs, lisa, cpm,
|
||||
msdos, highsierra, iso9660, appleshare.
|
||||
.SH ENVIRONMENT VARIABLES
|
||||
.IP \fBBLOCKSIZE\fR
|
||||
If the environment variable
|
||||
.BR BLOCKSIZE
|
||||
is set, the block counts will be displayed in units of that size block.
|
||||
.SH HISTORY
|
||||
.BR df
|
||||
for GNO/ME was originally built-in to gsh(1). The implementation of
|
||||
.BR df
|
||||
is based on FreeBSD source code and distributed with GNO/ME v2.0.6

The #ifdef's get quite messy, as there are certain filesystem things that

GNO/ME doesn't handle the same as UNIX. A lot of code is #ifdef'd out, but

left here with the thought that in the future some of it may be useful as

new libraries or FSTs are created.

The files gnodf.c contains a couple of UNIX library functions I've recreated

well enough to work for this applications, but I wouldn't even think of

adding to a library...
|

In particular, I muck with the statfs structure. DO NOT CALL statfs() or
|

fstatfs() with this structure. It may work and may cause a crash. This
|

structure is strictly for use with df(1) and the hacked functions in gnodf.c

which fill in fields with GS/OS calls, not kernel calls.
