DF(1) Commands and Applications DF(1)
df - display free disk space and disk usage statistics
df [-k] [-t FST list ] devnum | vol | file...
displays statistics about the amount of free disk space on the speci-
fied device number devnum (.d##), on the specified volume vol or on the
volume of which file is a part. More than one device number, volume,
or file may be listed, and types can be mixed in the argument list.
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.
The following options are available:
-k Use 1024-byte (1-Kbyte) blocks rather than the default. Note
that this overrides the BLOCKSIZE specification from the envi-
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 no to
specify the filesystem types for which action should not be
For example, the df command:
df -t nohfs,msdos
lists all filesystems except those of type HFS and MS-DOS
Acceptable filesystem types are as follows:
prodos, dos33, dos32, pascal, mfs, hfs, lisa, cpm, msdos, high-
sierra, iso9660, appleshare.
If the environment variable BLOCKSIZE is set, the block counts
will be displayed in units of that size block.
df for GNO/ME was originally built-in to gsh(1). The implementation of
df is based on FreeBSD source code and distributed with GNO/ME v2.0.6
