查看linux版本号的几种方法

(1)lsb_release 命令查看,FSG(Free Standards Group)组织开发的LSB (Linux Standard Base)标准的一个命令,用来查看linux兼容性的发行版信息

[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
