Could the var be > named something like PS_OPTS? Sure. I'm ok even if there is no Linux compatibility. If we choose an environment variable, I'm ok with any name as long as it makes sense. However Solaris had (I haven't used Solaris since Solaris 9) /usr/ucb for BSD compatible utilities. Should we consider something similar for linux compatibility? -- Cheers, Cy Schubert <Cy.Schubert@cschubert.com> FreeBSD UNIX: <cy@FreeBSD.org> Web: http://www.FreeBSD.org The need of the many outweighs the greed of the few.
