x cpu - CPU Information

Display CPU information and detect system endianness.

---

Quick Start

# Display CPU information (default)
x cpu

# Detect system endianness
x cpu endianness

---

Features

• CPU Info: Display processor details (model, cores, MHz, vendor, cache)
• Endianness Detection: Detect system byte order (little/big endian)
• Cross-platform: Linux (via /proc/cpuinfo) and macOS (via sysctl)

---

Commands

Command	Description
x cpu	Display CPU information (default)
x cpu info	Display CPU information
x cpu endianness	Detect system endianness (l/b)

---

Examples

CPU Information

# Default - show CPU info
x cpu

# Linux output example:
# processor                : 0
# model name               : Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz
# cpu cores                : 6
# cpu MHz                  : 2600.000
# vendor_id                : GenuineIntel
# cache size               : 12288 KB

# macOS output example:
# brand_string             : Intel(R) Core(TM) i7-9750H CPU @ 2.60GHz
# core_count               : 6
# thread_count             : 12

Endianness Detection

# Detect byte order
x cpu endianness

# Output: l (little-endian) or b (big-endian)

Platform Notes

Linux

• Reads from /proc/cpuinfo
• Shows: processor, model name, cpu cores, cpu MHz, vendor_id, cache size

macOS

• Uses sysctl machdep.cpu
• Shows: brand_string, core_count, thread_count, features

---

About Endianness

Value	Meaning
l	Little-endian (x86, x86_64, ARM)
b	Big-endian (some MIPS, PowerPC, SPARC)

Most modern systems use little-endian byte order.
