The /proc/cpuinfo virtual file contains a lot of information about the CPUs installed in our system. The following methods show the most useful tools, which are installed by default on almost any Linux distribution. There are several command line utilities we can use to obtain CPU information on Linux. $ – requires given linux commands to be executed as a regular non-privileged userĬheck CPU instruction set via command line # – requires given linux commands to be executed with root privileges either directly as a root user or by use of sudo command Privileged access to your Linux system as root or via the sudo command.

This will also include information about whether the CPU is 32 bit or 64 bit. In this tutorial, we will see how to obtain the CPU instruction set on Linux, from both command line and GUI. This means it is perfectly accessible for normal users, we just have to know where to look. Information about the instruction set of your CPU is stored in Linux, at the operating system level. For example, if your CPU supports hardware virualization, then that is part of its instruction set. The instruction set of a CPU is, in simple terms, the capabilities that it possesses.
