我最常用的也就两个：

uname -a
lsb_release -a

下面再分享几个常用的：

查看内核版本命令：

1. uname

[root@localhost ~]# uname
Linux

2. uname -r

[root@localhost ~]# uname -r

3. uname -a

[root@localhost ~]# uname -a

4. cat /proc/version

[root@localhost ~]# cat /proc/version

查看linux系统版本：

1. lsb_release -a(lsb为Linux Standard Base缩写)

[root@localhost ~]# lsb_release -a
