.SH SYNOPSIS
|
|
.BR df " [" -k "] [" -t
|
|
.IR "FST list"
|
|
]
|
|
.IR devnum

.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
