The command "fwupdmgr update" is used to update the firmware of software components on a Linux-based system. Here's what it does:

1. "fwupdmgr" is the name of the command-line tool that is used to manage firmware updates on Linux systems. It stands for Firmware Update Manager.

2. "update" is the specific action or subcommand of fwupdmgr that is being executed. In this case, it tells fwupdmgr to check for available updates and install them if necessary.

So, when you run the command "fwupdmgr update," the tool will connect to the relevant repositories or sources configured on your system, check for any available firmware updates for your software components (such as devices, drivers, or system BIOS), and install the updates if they are found.

This command is typically used on systems where firmware updates are supported by the manufacturer or distributor of the components.
