"This Smart card runs through 5 command line utilities that
are essential tools in displaying the current state of your system.
You may be thinking about installing the StarOffice package on your

too much RAM when running? Will it place an undue burden on the
system? All these questions can be answered by running df, free, ps
and top. We have also included the utility, w, in this Smart card
because it's another way of finding out the load on your system, as
well as displaying who is currently logged on the machine."
displays the amount of disk space available on the filesystem.
By default the space available on all the currently mounted
filesystems are shown.
sde@sparky:~ > df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda6 1886284 1363996 424920 76% /
/dev/hda5 3716 1134 2384 32% /boot
In this example we can see that the filesystem /dev/hda6 has over
400MB of free space available. df is therefore useful for
monitoring the free space available on each filesystem."
"As with any console utility there are many different command
line options that can be applied. For more information, please
consult either the man pages or the info files. For example, to
learn more about the ps command, type info ps at the shell
