查看linux版本號的幾種方法

(1)lsb_release 命令查看,FSG(Free Standards Group)組織開發的LSB (Linux Standard Base)標准的一個命令,用來查看linux兼容性的發行版信息


[root@enmoteam1 oracle]# lsb_release -h

FSG lsb_release v2.0 prints certain LSB (Linux Standard Base) and
Distribution information.


Usage: lsb_release [OPTION]...
With no OPTION specified defaults to -v.


Options:
  -v, --version
    Display the version of the LSB specification against which the distribution is compliant.
  -i, --id
    Display the string id of the distributor.
  -d, --description
    Display the single line text description of the distribution.
  -r, --release
    Display the release number of the distribution.
  -c, --codename
    Display the codename according to the distribution release.
  -a, --all
    Display all of the above information.
  -s, --short
    Use short output format for information requested by other options (or version if none).
  -h, --help
    Display this message.
[root@enmoteam1 oracle]# lsb_release -v

[root@enmoteam1 oracle]# lsb_release -i

[root@enmoteam1 oracle]# lsb_release -a
LSB Version:    :core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch

[root@enmoteam1 oracle]# 


(2)/etc/issue查看,是系統安裝時默認的發行版本號信息。通常安裝好系統後文件內容不會發生變化

[root@enmoteam1 oracle]# cat  /etc/issue

(3)/proc/version 和 uname -a 顯示的內容同樣,顯示linux內核版本。

[root@enmoteam1 oracle]# cat /proc/version

[root@enmoteam1 oracle]# uname -r

[root@enmoteam1 oracle]# uname -a

[root@enmoteam1 oracle]# 


(4)/etc/redhat-release能夠看到詳細的版本
