The clear <envar> removes an environment variable. However, some
environment variables, such as tta0_baud, are permanent and cannot be
removed.
The clear <envar> 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 7-3
).
