The "cpuid" command (short for CPU ID) is a system utility typically used in computer programming and debugging to obtain information about the processor (CPU) installed in a computer.

When the "cpuid" command is executed, it retrieves various details about the CPU, such as the manufacturer, model, family, and features. This information can be helpful for understanding the capabilities of the CPU and tailoring software accordingly.

Different operating systems may have their own implementation of the "cpuid" command. In some cases, it may be an executable program with various command-line options, while in others, it can be a function or instruction within assembly language.

The output of the "cpuid" command varies depending on the specific implementation, but it usually presents information in a structured format, such as numeric codes or hexadecimal values, enabling developers or system administrators to easily interpret the results.
