The pkg Command

The pkg command is the command-line equivalent to Update Tool. Most of the tasks that can be performed with the graphical Update Tool can be performed from a command line using the pkg tool.

The pkg command is located in the as-install-parent/bin directory. To run the pkg command without specifying the path, ensure that this directory is in your path.

The pkg command enables you to create update scripts and to update software on headless systems. A headless system does not have a monitor, graphics card, or keyboard.

Most of the procedures in this chapter are based on the pkg command. A set of reference pages that contain details about using the pkg command is included with GlassFish Serverin the as-install-parent/pkg/man directory.
