Linux常用命令之查看版本

1.Linux查看版本当前操作系统内核信息

uname -a

Linux localhost.localdomain 2.6.32-504.el6.x86_64 #1 SMP Wed Oct 15 04:27:16 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

2.Linux查看当前操作系统版本信息

cat /proc/version

Linux version 2.6.32-504.el6.x86_64 ([email protected]) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC) ) #1 SMP Wed Oct 15 04:27:16 UTC 2014

3.Linux查看版本当前操作系统发行版信息

cat /etc/issue 或cat /etc/redhat-release

CentOS release 6.10 (Final)

4.Linux查看cpu相关信息，包括型号、主频、内核信息等

cat /proc/cpuinfo
