linux的vi完全不懂，求助大神
使用vi打开一个新文档，输入以下两段内容：
Linux is an operating system that was initially created as a hobby by a young student, Linus Torvalds, at the University of Helsinki in Finland. Linus had an interest in Minix, a small UNIX system, and decided to develop a system that exceeded the Minix standards.
The kernel, at the heart of all Linux systems, is developed and released under the GNU General Public License and its source code is freely available to everyone. It is this kernel that forms the base around which a Linux operating system is developed.
1、发出命令显示行号。
2、保存到文件AboutLinux，并不退出。
3、删除一句“It is this kernel that forms the base around which a Linux operating system is developed.”。
4、查找单词“Finland”。
5、把第一段的“Finland”单词后的内容换行，使其变成三段内容。
6、将第二段的内容复制到文档的最后。
7、删除第三段的内容。
8、恢复被删除的一段内容。
9、查找所有的“Minix”单词，并全部改为“MINIX”。
10、不保存修改，退出vi。
11、使用vi再次打开文件AboutLinux，在第二段后插入“He began his work in 1991 when he released version 0.02 and worked steadily until 1994 when version 1.0 of the Linux Kernel was released.”。
12、保存并退出vi。
