Passing parameters to sql*plus ??

Howdy (or something) !

How do I pass parameters to sqlplus on startup of a script ? I have been able to do a workaround to this by using an append of define *something* into login.sql from a unix shell-scipt, but i don't like this approach.

Is it possible to access Unix env. variables from inside sql*plus ?

Any help appreciated !
