In Linux, you can view hardware information such as CPU information and machine model

Hardware information for testing machines:

View CPU Information (Model)
# cat /proc/cpuinfo | grep name | cut -f2 -d: | uniq -c
   8  Intel(R) Xeon(R) CPU          E5410 @ 2.33GHz
(I saw that there are 8 logical CPUs, and I also know the CPU model)

# cat /proc/cpuinfo | grep physical | uniq -c
   4 physical id    : 0
   4 physical id    : 1
(Explain that it is actually two 4-core CPUs)

# getconf LONG_BIT
32
(It means that the current CPU is running in 32-bit mode, but it does not mean that the CPU does not support 64-bit)

# cat /proc/cpuinfo | grep flags | grep ' lm ' | wc -l
8
(The result is greater than 0, indicating that it supports 64-bit computing. lm refers to long mode, and lm is 64bit)

A full look at the CPU details, but most of us just don't care.
