I can't really show the code in Unix, but I can explain it very clearly. In the terminal, when you type "df", you get information on the disk free space all in KILOBYTE units. KILOBYTES is currently set as the default in Unix. My problem is trying to change the default from KILOBYTES to MEGABYTES. After changing of the default, I should be able to type in "df" and all the disk free space should come up in MEGABYTES.
