 == DESCRIPTION
 
-*lscpu* gathers CPU architecture information from _sysfs_, _/proc/cpuinfo_ and any applicable architecture-specific libraries (e.g. *librtas* on Powerpc). The command output can be optimized for parsing or for easy readability by humans. The information includes, for example, the number of CPUs, threads, cores, sockets, and Non-Uniform Memory Access (NUMA) nodes. There is also information about the CPU caches and cache sharing, family, model, bogoMIPS, byte order, stepping and microcode.

 The default output formatting on a terminal is subject to change and may be optimized for better readability. The output for non-terminals (e.g., pipes) is never affected by this optimization and it is always in "Field: data\n" format. Use for example "*lscpu | less*" to see the default output without optimizations.
