What is the command to examine hardware and system information?

The command that is commonly used to examine detailed hardware and system information is "inxi." This tool provides a comprehensive overview of the hardware and software configuration of a Linux system, which makes it particularly useful for troubleshooting, system auditing, and providing system information to users or support personnel.

Inxi can output information about various components such as CPU, RAM, disk drives, network interfaces, and much more with a simple command. Its format is designed for readability and can include various levels of detail based on the options used when executing the command.

Other tools that might provide information about hardware include programs like "lshw" or "hwinfo," but inxi is known for its user-friendly output and broad range of information, hence why it is often favored among users needing to gather system information quickly.
