-I know, I know! You could just hit the UP arrow to bring up the command you just ran, and navigate to the misspelled word using the LEFT/RIGHT keys, and correct the misspelled word(s), finally hit ENTER key to run it again, right? But, wait. There is another easier way to correct misspelled Bash commands in GNU/Linux. This brief tutorial explains how to do it. Read on.
-
-### Correct Misspelled Bash Commands In Linux
-
-Have you run a mistyped command something like below?
-```
-$ unme -r
-bash: unme: command not found
-
-```
-
-Did you notice? There is a typo in the above command. I missed the letter “a” in the “uname” command.
-
-I have done this kind of silly mistakes in many occasions. Before I know this trick, I used to hit UP arrow to bring up the command and go to the misspelled word in the command, correct the spelling and typos and hit the ENTER key to run that command again. But believe me. The below trick is super easy to correct any typos and spelling mistakes in a command you just ran.
-
-To easily correct the above misspelled command, just run:
-```
-$ ^nm^nam^
-
-```
-
-This will replace the characters “nm” with “nam” in the “uname” command. Cool, yeah? It’s not only corrects the typos, but also runs the command. Check the following screenshot.
-
-![][2]
-
-Use this trick when you made a typo in a command. Please note that it works only in Bash shell.
-
-**Bonus tip:**
-
-Have you ever wondered how to automatically correct spelling mistakes and typos when using “cd” command? No? It’s alright! The following trick will explain how to do it.
-
-This trick will only help to correct the spelling mistakes and typos when using “cd” command.
-
-Let us say, you want to switch to “Downloads” directory using command:
-```
-$ cd Donloads
-bash: cd: Donloads: No such file or directory
-
-```
-
-Oops! There is no such file or directory with name “Donloads”. Well, the correct name was “Downloads”. The “w” is missing in the above command.
-
-To fix this issue and automatically correct the typos while using cd command, edit your **.bashrc** file:
-```
-$ vi ~/.bashrc
-
-```
-
-Add the following line at end.
-```
-[...]
-shopt -s cdspell
-
-```
-
-Type **:wq** to save and exit the file.
-
-Finally, run the following command to update the changes.
-```
-$ source ~/.bashrc
-
-```
-
-Now, if there are any typos or spelling mistakes in the path while using cd command, it will automatically corrects and land you in the correct directory.
-
-![][3]
-
-As you see in the above command, I intentionally made a typo (“Donloads” instead of “Downloads”), but Bash automatically detected the correct directory name and cd into it.
-
-[**Fish**][4] and **Zsh** shells have this feature built-in. So, you don’t need this trick if you use them.
-
-This trick, however, has some limitations. It works only if you use the correct case. In the above example, if you type “cd donloads” instead of “cd Donloads”, it won’t recognize the correct path. Also, if there were more than one letters missing in the path, it won’t work either.

+如何在 Linux 中轻松修正拼写错误的 Bash 命令
+======
+
+![](https://www.ostechnix.com/wp-content/uploads/2018/02/Correct-Misspelled-Bash-Commands-720x340.png)
+
+我知道你可以按下向上箭头来调出你运行过的命令，然后使用左/右键移动到拼写错误的单词，并更正拼写错误的单词，最后按回车键再次运行它，对吗？可是等等。还有一种更简单的方法可以纠正 GNU/Linux 中拼写错误的 Bash 命令。这个教程解释了如何做到这一点。请继续阅读。
+
+### 在 Linux 中纠正拼写错误的 Bash 命令
+
+你有没有运行过类似于下面的错误输入命令？
+```
+$ unme -r
+bash: unme: command not found
+
+```
+
+你注意到了吗？上面的命令中有一个错误。我在 “uname” 命令缺少了字母 “a”。
+
+我在很多时候犯过这种愚蠢的错误。在我知道这个技巧之前，我习惯按下向上箭头来调出命令并转到命令中拼写错误的单词，纠正拼写错误，然后按回车键再次运行该命令。但相信我。下面的技巧非常易于纠正你刚刚运行的命令中的任何拼写错误。
+
+要轻松更正上述拼写错误的命令，只需运行：
+```
+$ ^nm^nam^
+
+```
+
+这会将 “uname” 命令中将 “nm” 替换为 “nam”。很酷，是吗？它不仅纠正错别字，而且还能运行命令。查看下面的截图。
+
+![][2]
+
+当你在命令中输入错字时使用这个技巧。请注意，它仅适用于 Bash shell。
+
+**额外提示：**
+
+你有没有想过在使用 “cd” 命令时如何自动纠正拼写错误？没有么？没关系！下面的技巧将解释如何做到这一点。
+
+这个技巧只能纠正使用 “cd” 命令时的拼写错误。
+
+比如说，你想使用命令切换到 “Downloads” 目录：
+```
+$ cd Donloads
+bash: cd: Donloads: No such file or directory
+
+```
+
+哎呀！没有名称为 “Donloads” 的文件或目录。是的，正确的名称是 “Downloads”。上面的命令中缺少 “w”。
+
+要解决此问题并在使用 cd 命令时自动更正错误，请编辑你的 **.bashrc** 文件：
+```
+$ vi ~/.bashrc
+
+```
+
+最后添加以下行。
+```
+[...]
+shopt -s cdspell
+
+```
+
+输入 **:wq** 保存并退出文件。
+
+最后，运行以下命令更新更改。
+```
+$ source ~/.bashrc
+
+```
+
+现在，如果在使用 cd 命令时路径中存在任何拼写错误，它将自动更正并进入正确的目录。
+
+![][3]
+
+正如你在上面的命令中看到的那样，我故意输错（“Donloads” 而不是 “Downloads”），但 Bash 自动检测到正确的目录名并 cd 进入它。
+
+[**Fish**][4] 和**Zsh** shell 内置的此功能。所以，如果你使用的是它们，那么你不需要这个技巧。
+
+然而，这个技巧有一些局限性。它只适用于使用正确的大小写。在上面的例子中，如果你输入的是 “cd donloads” 而不是 “cd Donloads”，它将无法识别正确的路径。另外，如果路径中缺少多个字母，它也不起作用。
