Using DF - Command Line Options

df [ -a | drive_1 [ drive_2 ... ] | -? ]
If DF is not given an argument, it will print the free space information for the default drive.
Otherwise, unless the -a option is specied, DF prints the free space information for each of
the supplied arguments.
Example: df a: b: prints the available free space for drives a: and b:.
The options for DF are:
-a: Print free space for all loadable drives.
-?: Display program description.
Note:
If the environment variable DF exists, its value is used to establish default options.
You can override an option that was specied in the environment variable by following the
option with a minus '-' sign. For example, to turn off the -a option, specify -a-.
Option -a can be specied twice to restore normal operation, namely, to undo the effect of
specifying option -a in the environment variable.
