           lscpu [-a|-b|-c] [-x] [-s directory] [-e [=list]|-p [=list]]
           lscpu -h|-V


           lscpu   gathers   CPU   architecture   information   from   sysfs   and
           /proc/cpuinfo. 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, and stepping.
           Options that result in an output table have a list argument.  Use  this
           argument  to  customize  the  command output. Specify a comma-separated
           list of column labels to limit the output table to only  the  specified
           columns,  arranged  in  the  specified order. See COLUMNS for a list of
           valid column labels. The column labels are not case sensitive.
           Not all columns are supported on all architectures. If  an  unsupported
           column  is  specified, lscpu prints the column but does not provide any
           data for it.
           CPU    The logical CPU number of a CPU as used by the Linux kernel.
           CORE   The logical core number. A core can contain several CPUs.
           SOCKET The logical socket number. A socket can contain several cores.
           BOOK   The logical book number. A book can contain several sockets.
           NODE   The logical NUMA node number. A node may contain several  books.
           CACHE  Information about how caches are shared between CPUs.
                  The physical address of a CPU.
           ONLINE Indicator  that shows whether the Linux instance currently makes
                  use of the CPU.
                  Indicator that shows if the hypervisor has allocated the CPU  to
                  the virtual hardware on which the Linux instance runs. CPUs that
                  are configured can be set online by the  Linux  instance.   This
                  column contains data only if your hardware system and hypervisor
                  support dynamic CPU resource allocation.
                  This column contains data for Linux instances that run  on  vir-
                  Include lines for online and offline CPUs in the output (default
                  for -e). This option may only specified together with option  -e
                  or -p.
           -b, --online
                  Limit  the  output  to online CPUs (default for -p). This option
                  may only be specified together with option -e or -p.
           -c, --offline
                  Limit the output to offline CPUs. This option may only be speci-
                  fied together with option -e or -p.
           -e, --extended [=list]
                  Display the CPU information in human readable format.
                  If  the  list argument is omitted, all columns for which data is
                  available are included in the command output.
                  When specifying the list argument, the string of  option,  equal
                  sign  (=),  and  list must not contain any blanks or other white
                  space.  Examples: '-e=cpu,node' or '--extended=cpu,node'.
           -h, --help
                  Display help information and exit.
           -p, --parse [=list]
                  Optimize the command output for easy parsing.
                  If the list argument is omitted, the command output is  compati-
                  ble  with  earlier versions of lscpu. In this compatible format,
                  two commas are used to separate CPU cache  columns.  If  no  CPU
                  caches are identified the cache column is omitted.
                  If the list argument is used, cache columns are separated with a
                  colon (:).
                  When specifying the list argument, the string of  option,  equal
                  sign  (=),  and  list must not contain any blanks or other white
                  space.  Examples: '-p=cpu,node' or '--parse=cpu,node'.
           -s, --sysroot directory
                  Gather CPU data for a Linux instance  other  than  the  instance
                  from  which the lscpu command is issued. The specified directory
                  is the system root of the Linux instance to be inspected.
           -x, --hex
                  Use hexadecimal masks for  CPU  sets  (for  example  0x3).   The
                  default is to print the sets in list format (for example 0,1).
           -V, --version
                  Display version information and exit.
