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:
| Argument | Description |
|---|---|
--version | Show program version information. |
-h, --help | Show this help message and exit. |
-v, --verbose | Show additional output. |
-l, --list | List the latest versions of all packages installed. |
-p, --packages | Update packages associated with this System Profile. |
--hardware | Update this system's hardware profile on RHN. |
--showall | List all packages available for download. |
--show-available | List all the packages available that are not currently installed. |
--show-orphans | List all the packages currently installed that are not in channels the system is subscribed to. |
--show-channels | Show the channel names along with the package names where appropriate. |
--installall | Install all available packages. Use with --channel. |
--channel=CHANNEL | Specify which channels to update from using channel labels. |
--get | Fetch the package specified without resolving dependencies. |
