    With vi, to get into the file:
    vi /etc/security/users

    To move to the correct line, use / to search, eg:
    /oracle
    /maxage

    Once on the correct line, press the "l" key repeatedly until the curser is
    over the 8. Press "r" for replace, then "0" to replace the 8 with 0.

    To write out the file, type ":wq".

    If you goof up and want to exit without writing the file, type ":q!"

    Maybe practice on a copy of the file.
