can backtick (or combination of other scripts commands) can be to NOT set env var on error?
I'm pretty sure that any case can be achieved with the current behaviour, but I agree that ugly contorsions are necessary for more than one case, so I'm ok to add an option switch - but the semantics need to be right (and it won't be -z, which I prefer to only use for something related to reaping z-ombies) What exactly is the behaviour you want: - don't exit on error, just keep exec'ing + do you just define "error" as the subprocess exiting anything else than 0 ? - but completely undefine the variable, in order for later tests such as importas to pick that up? Is that right, or have I missed something? -- Laurent
