1、Linux查看版本当前操作系统内核信息
# uname -a
Linux localhost.localdomain 2.4.20-8 #1 Thu Mar 13 17:54:28 EST 2003 i686 athlon i386 GNU/Linux
2、Linux查看当前操作系统版本信息
# cat /proc/version
Linux version 2.4.20-8 (bhcompile@porky.devel.redhat.com)
(gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)) #1 Thu Mar 13 17:54:28 EST 2003
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
Red Hat Linux release 9 (Shrike)
4、Linux查看cpu相关信息,包括型号、主频、内核信息等
# cat /proc/cpuinfo
