    That's not really how this works. Please read the link in my signature on asking questions the smart way, then try again.

    Also, you've posted this in a forum meant for introducing yourself, not for asking questions.

    Given you've mentioned nothing about what you've tried, or even if this is a java question, I'll point you to the following:
    diff - Linux Command - Unix Command
