vim入门使用与配置

vim相关知识积累，持续更新中。

常用操作

一般模式

• n1,n2s/word1/word2/gn1行与n2行间寻找word1，替换为word2
• 1,$s/word1/word2/g第一行到最后一行寻找word1，替换为word2
• N[Enter] 向下移动n行
• 0 : 移动到该行最后一个字符
• $ : 移动到该行第一个字符
• G : 最后一行
• gg : 首行
• x&X: x相当于[Del],X相当于[Backspace]
• dd : 删除该行
• yy : 复制该行
• nyy: 向下复制n行
• p&P: p贴到下一行，P贴到上一行
• u : 复原前一个操作
• / : 查找,可使用【n】键(next),在结果间跳转

切换到命令行

• :!command 暂时离开执行command的显示结果
• set nu 显示行号

块选择

按下v或者V或者[Ctrl]-v时，这个时候光标经过的地方会开始反白，y键可复制，d键可删除

替换文本中指定字符

在命令模式下

:%s/需要被替换的字符/新的字符/g

% 为正则表达式，表示文本结束，s 为 substitute 首字符，g 表示全局

环境设置与记录

vim的环境设置参数有很多，如果你想要知道目前的设置值，可以再一般模式时输入set all来查阅，不过设置选项实在太多了，在这里列出一些平时比较常用的一些简单的设置值

也可以通过配置文件来直观规定我们习惯的vim操作环境。整个vim的设置值一般是放置在/etc/vimrc这个文件中，不过，不建议直接修改它。建议修改文件~/.vimrc这个文件（默认不存在，请自行手动创建），将希望的设置值列入。

set hlsearch        "高亮度反白
set backspace=2     "课随时用退格键删除
set autoindent      "自动缩排
set ruler           "课显示最后一行的状态
set showmode        "左下角那一行的状态
set nu              "行号
set bg=dark         "显示不同的底色色调
syntax on           "语法高亮
