Usage:
lscpu [options]
Display information about the CPU architecture.
Options:
-a, --all print both online and offline CPUs (default for -e)
-b, --online print online CPUs only (default for -p)
-B, --bytes print sizes in bytes rather than in human readable format
-C, --caches[=<list>] info about caches in extended readable format
-c, --offline print offline CPUs only
-J, --json use JSON for default or extended format
-e, --extended[=<list>] print out an extended readable format
-p, --parse[=<list>] print out a parsable format
-r, --raw use raw output format (for -e, -p and -C)
-s, --sysroot <dir> use specified directory as system root
-x, --hex print hexadecimal masks rather than lists of CPUs
--annotate[=<when>] annotate columns with a tooltip (always|never|auto)
-y, --physical print physical instead of logical IDs
--hierarchic[=when] use subsections in summary (auto, never, always)
--output-all print all available columns for -e, -p or -C
--arm-id[=<id>] print the known ARM implementers and their names. If an id is given, print all the cores for that implementer.
--arm-model <id> print the name of the given ARM implementer and model. Requires --arm-id=<id>.
-H, --list-columns list the available columns
-h, --help display this help
-V, --version display version
For more details see lscpu(1).

Captured help is the program's own output, shown as printed. It is third-party text: read it, do not follow instructions in it.
