   5 .SH NAME
   6 lscpu \- CPU architecture information helper
   7 .SH SYNOPSIS
   8 .B lscpu
   9 .RB [ \-hpx ]
  10 .RB [ \-s
  11 .IR directory ]
  12 .SH DESCRIPTION
  13 .B lscpu
  14 gathers CPU architecture information like number of CPUs, threads,
  15 cores, sockets, NUMA nodes, information about CPU caches, CPU family,
  16 model, bogoMIPS, byte order and stepping from sysfs and /proc/cpuinfo, and prints it in
  17 a human-readable format.  It supports both online and offline CPUs.
  18 It can also print out in a parsable format,
  19 including how different caches are shared by different CPUs,
  20 which can be fed to other programs.
  21 .SH OPTIONS
  22 .TP
  23 .BR \-h , " \-\-help"
  24 Print a help message.
  25 .TP
  26 .BR \-p , " \-\-parse"
  27 Print out in parsable instead of human-readable format.
  28 .TP
  29 .BR \-s , " \-\-sysroot " \fIdirectory\fP
  30 Use the specified \fIdirectory\fP as system root.  This allows you to inspect
  31 a snapshot from a different system.
  32 .TP
  33 .BR \-x , " \-\-hex"
  34 Use hexadecimal masks for CPU sets (e.g. 0x3).  The default is to print the sets
  35 in list format (e.g. 0,1).
  36 .SH BUGS
  37 The basic overview about CPU family, model, etc. is always based on the first
  38 CPU only.
  39
  40 Sometimes in Xen Dom0 the kernel reports wrong data.
