OSのバージョンやカーネルなどのバージョン・システム情報を調べる方法

 
※この方法はいくつかの方法がありますので、その一例を紹介します。
 
1) CentOSの場合
環境：　CentOS 5.5 x86_64
 
# cat /proc/version
Linux version 2.6.18-194.26.1.el5 (mockbuild@builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-48)) #1 SMP Tue Nov 9 12:54:20 EST 2010

# cat /proc/version
Linux version 2.6.18-194.26.1.el5 (mockbuild@builder10.centos.org) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-48)) #1 SMP Tue Nov 9 12:54:20 EST 2010

# cat /etc/redhat-release
CentOS release 5.5 (Final)

# cat /etc/issue
CentOS release 5.5 (Final)
Kernel \r on an \m

# yum list installed | grep "centos-release*"
centos-release.x86_64                   10:5-5.el5.centos              installed
centos-release-notes.x86_64             5.5-0                          installed

# rpm -qa | grep "centos-release*"
centos-release-5-5.el5.centos
centos-release-notes-5.5-0

# uname --kernel-release
