Preferences are classified on the basis of their duration. Permanent preferences retain their settings until they are reset; transient preferences revert to a default setting at the start of a new installation session. A third group of preferences have potential to cause installation errors when set arbitrarily; these preferences are classified as expert.
Most preferences are assigned simple Boolean values; that is, you use the set command to turn them on or off. You can also substitute true (for on) and false (for off) when setting these preferences. These examples illustrate equivalent command pairs:
Admin> set beep on Admin> set beep true Admin> set short_names off Admin> set short_name false
