1. vi編輯器的三種模式

學會使用vi編輯器是學習linux系統的必備技術之一，因為一般的linux伺服器是沒有GUI介面的，linux運維及開發人員基本上都是通過命令列的方式進行文字編輯或程式編寫的。vi編輯器是linux內建的文字編輯器，幾乎所有的類unix系統中都內建了vi編輯器，而其它編輯器則不一定，另外很多軟體會呼叫vi編輯進行內容編寫，例如crontab定時任務。較之於其它編輯器或GUI編輯器，vi編輯速度是最快的。vim編輯器可以看作vi的高階版本，它實現了用顏色來進行特殊資訊的顯示，例如在進行java程式開發是，它會對某些關鍵字用顏色顯示。

vim編輯器： 

vi編輯器有三種模式，分別是一般模式、編輯模式及命令列模式 
1 一般模式，採用vi命令直接進入一般模式 
例如

<code class="hljs ruby has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">root<span class="hljs-variable" style="color: rgb(102, 0, 102); box-sizing: border-box;">@ubuntu</span><span class="hljs-symbol" style="color: rgb(0, 102, 102); box-sizing: border-box;">:/home/xtwy/compresse_demo</span><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;"># vi /etc/profile</span>
</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li></ul>

 
在一般模式下，可以進行上下左右的游標移動、刪除字元、行，還可以進行復制和貼上操作

2 編輯模式，在一般模式中按”i,l,o,O,a,A,r,R”等做任意一個字元後，將進入編輯模式，下面給出的是在一般模式下輸入”i”後，得到的編輯模式視窗。 
 
視窗最底下會顯示– INSERT–,此時可以對文字內容進行編輯模式，注意因為機器上已經安裝了vim，所以顯示時有顏色。

3 命令列模式 
在編輯模式中，按”ESC”鍵可以回到一般模式。在一般模式中，輸入”:,/,?”做任意一個字元，游標將移動到視窗底部，此時可以儲存編輯好的檔案或離開vi編輯器等，下圖給出的是輸入”:”之後得到的命令列模式視窗 

2. 移動游標

1 單個字元移動 
在一般模式化中，採用Up Arrow, Down Arrow鍵可以左右進行字元移動，也可以採用鍵盤上的 H、L鍵進行字元左右移動 
空格鍵也可以單個字元地向右移動。

2 移動到某個特定字元 
採用fx命令進行字元定位，例如fs可以定位到同一行s下一次現出的位置 
 
按下fs後游標位置 

採用Fx命令，可以將游標定位到x字元在同一行上一次出現的位置

3 按word移動

w命令將游標移動到下一下word的首字母，標點符號也算一個字。例如有下列文字：

<code class="hljs scala has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">【游標在這】<span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">class</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Student</span><span class="hljs-params" style="color: rgb(102, 0, 102); box-sizing: border-box;">(name:String,age:Int,val studentNo:String)</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">extends</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Person</span></span>

在一般模式下，按<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>w之後
<span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">class</span> 【游標在這】<span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Student</span><span class="hljs-params" style="color: rgb(102, 0, 102); box-sizing: border-box;">(name:String,age:Int,val studentNo:String)</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">extends</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Person</span></span>
</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>

W命令利用空格移動游標，例如

<code class="hljs scala has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">class</span> 【游標在這】<span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Student</span><span class="hljs-params" style="color: rgb(102, 0, 102); box-sizing: border-box;">(name:String,age:Int,val studentNo:String)</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">extends</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Person</span></span>

在一般模式下，按<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>W之後
<span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">class</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Student</span><span class="hljs-params" style="color: rgb(102, 0, 102); box-sizing: border-box;">(name:String,age:Int,val 【游標在這】studentNo:String)</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">extends</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Person</span></span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>

B命令利用空格向後移動游標，例如

<code class="hljs scala has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">class</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Student</span><span class="hljs-params" style="color: rgb(102, 0, 102); box-sizing: border-box;">(name:String,age:Int,val 【游標在這】studentNo:String)</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">extends</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Person</span></span>

在一般模式下，按<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>W之後
<span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">class</span> 【游標在這】<span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Student</span><span class="hljs-params" style="color: rgb(102, 0, 102); box-sizing: border-box;">(name:String,age:Int,val studentNo:String)</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">extends</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Person</span></span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li></ul>

b命令利用word包括標點向後移動游標，例如

<code class="hljs scala has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">class</span> 【游標在這】<span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Student</span><span class="hljs-params" style="color: rgb(102, 0, 102); box-sizing: border-box;">(name:String,age:Int,val studentNo:String)</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">extends</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Person</span></span>
在一般模式下，按<span class="hljs-number" style="color: rgb(0, 102, 102); box-sizing: border-box;">1</span>b之後
【游標在這】<span class="hljs-class" style="box-sizing: border-box;"><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">class</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Student</span><span class="hljs-params" style="color: rgb(102, 0, 102); box-sizing: border-box;">(name:String,age:Int,val studentNo:String)</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">extends</span> <span class="hljs-title" style="box-sizing: border-box; color: rgb(102, 0, 102);">Person</span></span>

5 螢幕位置移動 
H(home）移動到螢幕最頂部，下面的圖是沒有按H鍵時游標位置 
 
按完鍵後， 
 
按L鍵可以將游標移動到螢幕最底部，下面的圖是上圖按L鍵之後的效果 
 
按M鍵可以將游標移動到螢幕中間，下圖是上圖按M鍵後的效果 

CTR+D(Down）向下翻屏移動游標，CTR+U(UP)向上翻屏移動游標，命令前面還可以加數字表示翻屏多少行

CTR+F(Forward）與PageDown鍵，顯示下一屏文字；CTR+B（Backward）與PageUp顯示上一屏改文字。

G(Globalize）命令將游標移動到指定行號，例如1G，移動到文字第一行

3. 編輯模式

1 插入文字 
在一般模式下，按”I、i、a或A”進行文字插入，其中i命令用於在游標之前插入文字內容，I表示在行開始插入，a表示在游標之後插入，A則表示在行尾插入。

<code class="hljs autohotkey has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">（I在這插入）Downloa(i在這插入）【游標在這】（<span class="hljs-literal" style="color: rgb(0, 102, 102); box-sizing: border-box;">a</span>在這插入）ding（<span class="hljs-literal" style="color: rgb(0, 102, 102); box-sizing: border-box;">A</span>在這插入）</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li></ul>

2 新行輸入

o表示在當行下的下方建立一個新行，O表示在當前行的上方開啟一個新行

<code class="hljs cs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;"><span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">//O在游標所在行的上方插入新行</span>

3 文字替換 
命令r替換單個字元，替換完成後直接返回一般模式，命令R則連線已經文字替換，手動按ESC鍵後返回一般模式

4. 修改文字

在一般模式下進行文字的修改 
1 撤消修改
