五.查看当前机器操作系统版本
1>.查看红帽系列
[root@node101.yinzhengjie.org.cn ~]# cat /etc/redhat-release #仅红帽系列可用的命令，如RedHat,CentOS等 CentOS Linux release 7.6.1810 (Core) [root@node101.yinzhengjie.org.cn ~]#
2>.查看发行版本名称

[root@node101.yinzhengjie.org.cn ~]# who #系统当前所有的登录会话 root pts/0 2019-08-01 22:24 (172.30.1.1) root tty6 2019-08-01 22:53 [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# who am i #显示的还是蛮详细的 root pts/0 2019-08-01 22:24 (172.30.1.1) [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# whoami #显示当前登录有效用户 root [root@node101.yinzhengjie.org.cn ~]#
九.开机免密登录（一半用于自己的虚拟机的图形界面）
[root@node101.yinzhengjie.org.cn ~]# cat /etc/gdm/custom.conf # GDM configuration storage [daemon] AutomaticLoginEnable=true #我们这一行是启用开机自动登录 AutomaticLogin=root #我们这里使用的是root用户进行登录 [security] [xdmcp] [chooser] [debug] # Uncomment the line below to turn on debugging #Enable=true [root@node101.yinzhengjie.org.cn ~]#
十.查看当前所在的终端
[root@node101.yinzhengjie.org.cn ~]# tty /dev/pts/1 [root@node101.yinzhengjie.org.cn ~]#
十一.编写用户登录成功后的欢迎信息
[root@node101.yinzhengjie.org.cn ~]# cat /etc/motd #我们在这里写上相应的欢迎信息 welcome to https://www.cnblogs.com/yinzhengjie/ [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# logout #然后我们退出操作系统，由于我设置了重新连接的机制，基本上断开1秒后又重新连接啦。 Connection closed by foreign host.

十二.编写用户登录成功前的欢迎信息
[root@node101.yinzhengjie.org.cn ~]# cat /etc/issue #该配置文件在生产环境中建议把内核版本隐藏，不要出现welcome相关的词，如果黑客登录你的服务器你告他时，他反过来说你的设备写着"welcome"相关词语，你不应该惩罚我~那你就哑巴吃黄连，有苦说不出呀~ welcome to https://www.cnblogs.com/yinzhengjie/ !!! S Kernel on an m [root@node101.yinzhengjie.org.cn ~]#

5>.使用screen工具实现字符界面共享案例
[root@node101.yinzhengjie.org.cn ~]# who root :0 2019-08-02 16:30 (:0) root pts/0 2019-08-02 16:37 (:0) root pts/1 2019-09-03 19:38 (172.30.1.1) [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# screen -S help_me #用户A登录服务器，启动一个screen，并自定义名称为"help_me" [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# who root :0 2019-08-02 16:30 (:0) root pts/0 2019-08-02 16:37 (:0) root pts/2 2019-09-03 19:39 (172.30.1.1) root pts/4 2019-09-03 19:39 (172.30.1.1:S.0) [root@node101.yinzhengjie.org.cn ~]#
[root@node101.yinzhengjie.org.cn ~]# screen -ls #用户B登录同一台服务器，查看当前已经打开的screen会话 There are screens on: 32229.help_me (Attached) #不难发现"Attached"状态说明这个终端有人正在使用呢，而下面的"Detached"的终端还未有用户进去管理，但是里面执行的命令依旧建在！ 31644.pts-1.node101 (Detached) 2 Sockets in /var/run/screen/S-root. [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# screen -x help_me #用户B需要指定要连接的screen会话，登录用户A所启用的screen会话，即"help_me"，我们需要使用"-x"参数来指定screen会话名称 [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# who #登录成功后，你会立即得到一个画面，也就是当前用户A正在执行的Screen字符界面，你现在就可以和他实现桌面共享啦~ root :0 2019-08-02 16:30 (:0) root pts/0 2019-08-02 16:37 (:0) root pts/2 2019-09-03 19:39 (172.30.1.1) root pts/4 2019-09-03 19:39 (172.30.1.1:S.0) [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]#
十五.tab键
命令补全 内部命令： 外部命令： bash根据PATH环境变量定义的路径，自左而右在每个路径搜寻以给定命令名命名的文件，第一次找到的命令即为要执行的命令 用户给定的字符串只有一条惟一对应的命令，直接补全 否则，再次Tab会给出列表 路径补全 把用户给出的字符串当做路径开头，并在其指定上级目录下搜索以指定的字 符串开头的文件名 如果惟一：则直接补全 否则：再次Tab给出列表
案例如下： [root@node101.yinzhengjie.org.cn ~]# ls /etc/sysc #按2下tab键，可以把符合条件的路径列出来，供咱们选择 sysconfig/ sysctl.conf sysctl.d/ [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# [root@node101.yinzhengjie.org.cn ~]# ifc #按2下tab键，可以把符合条件的命令列出来，供咱们选择 ifcfg ifconfig [root@node101.yinzhengjie.org.cn ~]#
