DF(1) UNIX-wannabe commands for DOS DF(1)
NAME
df - display free disk space for all mounted drives
SYNOPSIS
df [ /? | -? | [drive...] ]
DESCRIPTION
df searches the system for floppy drives with inserted disks,
and for local and networked hard drives, and prints a summary of
the drives found with total, used, and free space for each drive.
If a floppy drive is present on the system, but has no disk
inserted, df does not display any information for that drive.
To limit the search to specific drives, specify the drives on
the command line.
OPTIONS
/? or -? Prints a brief help message and exits.
drive... One or more drives to scan. The default is to scan
all drives. Currently, df just checks the first
letter of each argument; therefore, A:, a:, and
aardvark all include the A: drive in the scan.
BUGS
The display gets ugly if you have a drive much bigger than two
gigabytes. This shouldn't be a problem for most people.
Kfree and Kused may not always add up to Ktotal due to round-
ing errors.
CD-ROMs are not supported. Running df on a CD-ROM drive does
not make much sense anyway.
EXAMPLES
df
checks all drives and prints a summary for each drive
found.
df /?
prints a brief help message and exits.
df a: c:
checks just the A: and C: drives.
AUTHORS
df was created by Larry Kollar, mainly from Other People's
Code. df is essentially a hack to the program "drives,"
which was posted to alt.msdos.programmer by Jon Freivald
<jaf@jaflrn.UUCP>.
The file ceh.asm, which contains the critical error handler,
was written by Jesse Chisholm with modifications by Jon
Freivald.
CAVEATS
I'm a technical writer who likes to play with dangerous
weapons (shotguns, C compilers, etc.). Use and abuse df at
your own risk.
