    I want to execute a command, redirect stderr and tee stdout
    e.g.
       tar ... 2>foo.err | tee foo.log

    however I also want to capture the exit status of the first command

       tar ... 2>foo.err | tee foo.log
       exitstatus = $?
    simply gets the exit status of tee of course

       tar ... || exitstatus=$? 2>foo.err | tee foo.log
    always sets exitstatus to zero, looks like I need to establish some
    precedence but brackets don't seem to help.

    Is there an idiom for this?

    Maybe I should hide the tar in a function?

    Apologies if the above is a FAQ, I've RTFM where M = "Learning the Korn
    Shell" and "Unix Power Tools", I'm none the wiser (though opening the
    latter is always good for a half hour off-topic diversion).
