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.
