As a tinkerer with soft routing systems, one must know how to use OpenWrt commands. It's easy to haphazardly install plugins for mips, aarch64, and X86 without distinguishing between architectures. At this point, commands to check the CPU architecture come in handy. Below are the OpenWrt query and maintenance commands organized by 彧繎，mainly related to hardware, system, disk, installation, and other commonly used commands.
