This article mainly shows you what are the commands for Linux system to view digits, which are easy to understand and clear, hoping to help you solve your doubts. Let's take you to study and learn this article "what are the commands for Linux system to view digits?"

1. [root @ linuxzgf ~] # getconf LONG_ bit [root @ linuxzgf ~] # getconf WORD_BIT (the int type and long type are generally 4 bytes in 32-bit systems, and the int type is still 4 bytes in 64-bit systems, but long has become the number of digits of word and long available in 8-byte inux systems using "getconf WORD_BIT" and "getconf LONG_BIT". You should get 32 and 64 in a 64-bit system, respectively. )

2. [root @ linuxzgf ~] # uname-an if there is x86room64, it is 64-bit, and the kernel is 64-bit if it is followed by X686 or X86room64, and the kernel is 32-bit if i686 or i386

Third, directly see if there is a method of / lib64 directory. 64-bit systems will have / lib64 and / lib directories, and 32-bit systems will have only / lib.

4. [root @ linuxzgf ~] # file / sbin/init/sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped32-bit is 32-bit linux. If it is 64-bit, it shows 64-bit.

5. [root @ linuxzgf ~] # file / bin/cat/bin/cat: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped32-bit is 32-bit linux. If it is 64-bit, it shows 64-bit.

6. [root @ linuxzgf ~] # uname-mx86_643.# archx86_64i686

7. Check how many bits of cpu are [root @ linuxzgf ~] # more / proc/cpuinfo

8. [root @ linuxzgf ~] # echo $HOSTTYPEx86_64

The getconf command can also get the basic configuration information of the system, such as operating system bits, memory size, disk size, and so on. $getconf-a can see detailed system information

What is Linux system Linux is a free-to-use and free-spread UNIX-like operating system, is a POSIX-based multi-user, multi-task, multi-threaded and multi-CPU operating system, using Linux can run major Unix tools, applications and network protocols.
