    Open the Terminal (in /Applications/Utilities) and type man update. It'll say:

    NAME
    update -- flush internal filesystem caches to disk frequently

    SYNOPSIS
    update [normal_interval [save_energy_interval]]

    DESCRIPTION
    The update command helps protect the integrity of disk volumes by flushing volatile cached filesystem data to disk at thirty
    second intervals. Update uses the sync(2) function call to do the task. The normal_interval and save_energy_interval can be
    used to set the sync(2) interval in seconds of the normal case and the case where the computer is trying to save energy.

    Update is invoked at startup time by launchd(8) when the system goes multi-user.

    SEE ALSO
    sync(2), fsck(8), launchd(8), sync(8)

    BUGS
    It is possible on some systems that a sync occurring simultaneously with a crash may cause file system damage. See fsck(8).

    HISTORY
    An update command appeared in Version 6 AT&T UNIX.
