lscpu [-hpx] [-s directory]
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 for-
mat, including how different caches are shared by different CPUs, which
can be fed to other programs.
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. Cur-
rently 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.
Use hexadecimal masks for CPU sets (e.g. 0x3). The default is
to print the sets in list format (e.g. 0,1).
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.
