    A particular program is generating an excessive amount of error messages (named "error" in this case) that are of no use to you and you want to discard them rather than have to wade through them as they appear in a console session. Choose the best command below that will accomplish your task:

    1. error > /dev/null
    2. error >> /dev/null
    3. error 0> /dev/null
    4. error 0>> /dev/null
    5. error 2> /dev/null
    6. error 2>> /dev/null

    Correct answer is 5. error 2> /dev/null. If you use the command error > /dev/null, error messages won't be picked up...just stdout messages.
