The clear <envar> removes an environment variable. However, some en-
vironment variables, such as baud, are permanent and cannot be re-
moved.
The clear command syntax is:
cl[ear] <envar>
where <envar> is the name of an environment variable, for example, a
boot specification to be cleared (see Table 2-3).
