NAME

       lscpu - display information on CPU architecture

SYNOPSIS

       lscpu [-hpx] [-s directory]

DESCRIPTION

       lscpu  gathers  CPU  architecture  information  like number of CPUs, threads, cores, sockets, NUMA nodes,
       information about CPU caches, CPU family, model,  bogoMIPS,  byte  order  and  stepping  from  sysfs  and
       /proc/cpuinfo,  and  prints it in a human-readable format.  It supports both online and offline CPUs.  It
       can also print out in a parsable format, including how different caches are  shared  by  different  CPUs,
       which can be fed to other programs.

OPTIONS

       -h, --help
              Print a help message.

       -p, --parse [=list]
              Print out in parsable instead of human-readable format.

              If  the  list argument is not given then the default backwardly compatible output is printed.  The
              backwardly compatible format uses two commas to separate CPU cache columns. If no CPU  caches  are
              identified, then the cache columns are not printed at all.

              The list argument is comma delimited list of the columns. Currently supported are CPU, Core, Node,
              Socket, Book and Cache columns. If the list argument is given then always  all  requested  columns
              are printed in the defined order. The Cache columns are separated by ':'.

              Note  that  the optional list argument cannot be separated from the option by a space, the correct
              form is for example '-p=cpu,node' or '--parse=cpu,node'.

       -s, --sysroot directory
              Use the specified directory as system root.   This  allows  you  to  inspect  a  snapshot  from  a
              different system.

       -x, --hex
              Use  hexadecimal  masks  for CPU sets (e.g. 0x3).  The default is to print the sets in list format
              (e.g. 0,1).

BUGS

       The basic overview about CPU family, model, etc. is always based on the first CPU only.

       Sometimes in Xen Dom0 the kernel reports wrong data.
