I don't think that's it. Aliases aren't in the environment and env won't invoke a shell (to create new aliases) implicitly. I guess that the purpose of 'env -i' is to clear the PATH to avoid custom versions of 'rm'. In order to find the official rm, env would need to supply a default PATH, presumably using execlp/execvp. -- Cheers, Clive -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
