檢視linux系統版本指令

一。檢視核心版本指令：

1） [root@sor_sys ~]# cat /proc/version

[root@sor_sys ~]#

2）[root@sor_sys ~]# uname -r

2.6.18-238.el5

3）[root@sor_sys ~]# uname -a

linux sor_sys.99bill.com 2.6.18-238.el5 #1 smp sun dec 19 14:22:44 est 2010 x86_64 x86_64 x86_64 gnu/linux

二。檢視linux版本：

1) 登入到伺服器執行 lsb_release -a ,即可列出所有版本資訊,例如:

[root@sor_sys ~]# lsb_release -a

lsb version:    :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch

distributor id: redhatenterpriseas

description:    red hat enterprise linux as release 4 (nahant update 4)

release:        4

codename:       nahantupdate4

注:這個指令适用于所有的linux，包括redhat、suse、debian等發行版。

2) 登入到linux執行cat /etc/issue,例如如下:

[root@sor_sys ~]# cat /etc/issue

red hat enterprise linux server release 5.6 (tikanga)

kernel \r on an \m

3) 登入到linux執行cat /etc/redhat-release ,例如如下:

[root@sor_sys ~]# cat /etc/redhat-release

red hat enterprise linux as release 4 (nahant update 4)

注:這種方式下可以直接看到具體的版本号，比如 as4 update 1

4)登入到linux執行rpm -q redhat-release ,例如如下:

[root@sor_sys ~]# rpm -q redhat-release

redhat-release-5server-5.6.0.3

注:這種方式下可看到一個所謂的release号，比如上邊的例子是5

這個release号和實際的版本之間存在一定的對應關系，如下：

　　redhat-release-3as-1 -> redhat enterprise linux as 3

　　redhat-release-3as-7.4 -> redhat enterprise linux as 3 update 4

　　redhat-release-4as-2 -> redhat enterprise linux as 4

　　redhat-release-4as-2.4 -> redhat enterprise linux as 4 update 1

　　redhat-release-4as-3 -> redhat enterprise linux as 4 update 2

　　redhat-release-4as-4.1 -> redhat enterprise linux as 4 update 3

　　redhat-release-4as-5.5 -> redhat enterprise linux as 4 update 4

另:第3)、4)兩種方法隻對redhat linux有效

5) [root@sor_sys ~]# file /bin/bash

/bin/bash: elf 64-bit lsb executable, amd x86-64, version 1 (sysv), for gnu/linux 2.6.9, dynamically linked (uses shared libs), for gnu/linux 2.6.9, stripped

6) [root@sor_sys ~]# file /bin/cat

/bin/cat: elf 64-bit lsb executable, amd x86-64, version 1 (sysv), for gnu/linux 2.6.9, dynamically linked (uses shared libs), for gnu/linux 2.6.9, stripped
