NAME
     softwareupdate -- system software update tool

SYNOPSIS
     softwareupdate command [args ...]

DESCRIPTION
     Software Update checks for new and updated versions of your software
     based on information about your computer and current software.

     Invoke softwareupdate by specifying a command followed by zero or more
     args.

     softwareupdate requires admin authentication for all commands except
     --list.  If you run softwareupdate as a normal admin user, you will be
     prompted for a password where required. Alternatively, you can run
     softwareupdate as root and avoid all further authentication prompts.

     The following commands are available:

     -l | --list
                 List all available updates.

     -i | --install
                 Each update specified by args is downloaded and installed.
                 args can be one of the following:

                 -r | --recommended
                             All updates that are recommended for your system.
                             These are prefixed with a * character in the
                             --list output.

                 -R | --restart
                             Automatically restart (or shut down) if required
                             to complete installation.

                 -a | --all  All updates that are applicable to your system,
                             including those non-recommended ones, which are
                             prefixed with a - character in the --list output.
                             (Non-recommended updates are uncommon in any
                             case.)

                 item ...    One or more specified updates. The --list output
                             shows the item names you can specify here, pre-
                             fixed by the * or - characters. See EXAMPLES.

     -d | --download
                 Each update specified by args is downloaded but not
                 installed. The values of args are the same as for the
                 --install command. Updates downloaded with --download can be
                 subsequently installed with --install, or through the App
                 Store (as long as they remain applicable to your system).
                 Updates are downloaded to /Library/Updates, but are not
                 designed to be installed by double-clicking the packages in
                 that directory: always use --install or the App Store to
                 actually perform the install.

     --ignore identifier ...
                 Manages the per-machine list of ignored updates. The
                 identifier is the first part of the item name (before the
                 dash and version number) that is shown by --list.  See
                 EXAMPLES.

     --reset-ignored
                 Clears the per-machine list of ignored updates.

     --schedule on | off
                 Manages the per-machine automatic (background) check prefer-
                 ence.

     -h | --help
                 Print command usage.
