Common Linux commands: view system information

1. view the number of operating system digits

File/sbin/init

Display

/Sbin/init: Elf 32-bit LSB shared object, Intel 80386,

Version 1 (sysv), dynamically linked (uses SHARED libs), for GNU/Linux 2.6.15, stripped

There is another way:

Getconf word_bit

32 is the operating system, and 64 is the 64-bit operating system.

Note: The relationship between the number of digits of the operating system and the number of digits of the CPU is not proportional.

A 32-bit operating system does not mean that the CPU is 32-bit. A 64-bit CPU supports a 32-bit operating system.

2. view the kernel version

Uname-

Linux mark 2.6.35-30-generic-pae # 59-ubuntu SMP Tue Aug 30 16:16:14 UTC 2011 i686 GNU/Linux

That is, 2.6.35-30

To view all installed Linux kernel versions, run the following command:

Dpkg -- Get-selections | grep Linux
