In *nix, you have to *be* the parent.  Other methods involve cooperation
with the parent.

You could make your command a shell alias which would
'eval' the output of your program:

chkenv() {		# SysV sh
eval `chkenv.prog`
}

'chkenv.prog' should output something like:

VAR1=abc; VAR2=def; export VAR1 VAR2

'csh' users need their own special syntax.
