The “arch” command is used to display the computer architecture information. When you run the “arch” command in a terminal or command prompt, it will output the architecture of the system, typically in a string format.
For example, on a 64-bit x86-based system, running the “arch” command would display “x86_64” as the output. On an ARM-based system, it might display “arm” or “arm64” depending on the specific architecture.
The “arch” command is often used to determine the architecture of a system programmatically or as part of a script.
