Yep, 'ps e' shows loads of parameters. All those in the shell .rc file, and sundry that are also put in at various stages by anything else the shell uses.
Now, however, unless someone is willing to pull out all the set env variables by this method, and get the relevant spam, just to catch out this guy, then it's all but invisible.
If it's a case of this is too visible for the poster, then, so be it, I just feel that it's 'within reasonable bounds' of not being visible to ps, and all the commonly used forms.
