8.3.2.3. Updating From the Command Line

Like the website, command line use of the Red Hat Update Agent is affected by the limitations of UNIX package management. That said, most core functions can still be accomplished through the up2date command. The most significant difference is the absence of all options regarding source files. Refer to Table 8.3, “Update Agent Command Line Arguments” for the precise list of options available for UNIX systems.
The command line version of the Red Hat Update Agent accepts the following arguments on UNIX systems:
