Hide Files and Folders in Linux Without Renaming Them
|
||||
======
|
||||
Brief: This beginner-focused article discusses how you can hide files and folders from normal view in Linux. Both GUI and command-line methods have been discussed.
|
||||
|
||||
There will be times when you need to hide files in Linux.
|
||||
|
||||
No, I am not talking about those ‘special files’ that you don’t want your family to see. Although you can hide these special files, it is better to lock them with a password for an extra layer of protection.
|
||||
|
||||
Back to hiding files. **Any file or folder whose name begins with a . (dot) is “hidden” in Linux.**
|
||||
|
||||
Linux has plenty of such files and folders that are hidden from the normal view. These are mainly config files that are needed by the system and programs.
|
||||
|
||||
The users don’t need them normally and hence they are hidden from the normal view so that you don’t get overwhelmed by so many strange-looking files that you never created.
|
||||
|
||||
Here’s a look at the hidden files and folders in my home directory.
|
||||
|
||||
![linux normal view][1]
|
||||
|
||||
![linux show hiiden files][2]
|
||||
|
||||
You can easily [view the hidden files][3] by pressing Ctrl+H in the file manager if you are using desktop Linux. In the terminal, you can use the ls -a command to display the hidden files along with the normal ones.
|
||||
|
||||
So, how do you create hidden files in Linux? You simply name them with a dot. Here’s how.
|
||||
|
||||
### Create hidden files and folders in Linux desktop (GUI method)
|
||||
|
||||
If you are using the file manager, right click on the file or folder and choose the rename option. Now all you have to do is to add a . at the beginning of the filename.
|
||||
|
||||
GNOME’s Nautilus file manager also shows a warning when you are creating a hidden file in this manner.
|
||||
|
||||
![hide files ubuntu linux][4]
|
||||
|
||||
You can hide a folder along with all its contents in the same way.
|
||||
|
||||
You can press Ctrl+H keys to display the hidden files. Oh! how much I love [keyboard shortcuts in Ubuntu][5] or any other program or OS I use.
|
||||
|
||||
To make the hidden files normal again, just rename them again by removing the dot from the beginning of the file name.
|
||||
|
||||
### Create hidden files and folders in Linux terminal (CLI method)
|
||||
|
||||
If you are stuck with the terminal, you can [use the mv command][6] to rename the file. You just have to rename the file by adding a . at the beginning of the original filename.
|
||||
|
||||
```
|
||||
mv filename .filename
|
||||
```
|
||||
|
||||
You can display the hidden files using this command:
|
||||
|
||||
```
|
||||
ls -la
|
||||
```
|
||||
|
||||
You may also use ls -lA. This one won’t show the dot files (. and ..).
|
||||
|
||||
### Bonus tip: Hide files and folders without renaming them (works in GUI only)
|
||||
|
||||
You just learned to hide files in Linux. The problem is that you have to rename the files and that’s not ideal in all situations.
|
||||
|
||||
For example, in Ubuntu, you’ll see a folder named ‘snap’ in your directory. You are not going to use it but if you rename it, your snap apps won’t work as expected. Similarly, there’s a firefox.tmp folder under the Downloads directory in Ubuntu 22.04 (for the snap version of Firefox).
|
||||
|
||||
There is a neat trick that can be used in the Linux desktop. It should work under various file managers like Nemo, Thunar, Dolphin etc but I cannot vouch for it. It sure works in the Nautilus file manager of GNOME.
|
||||
|
||||
So, what you do here is to create a new file named .hidden in the directory where your desired files or folders (to be hidden) are located.
|
||||
|
||||
![alternate way of hiding files in linux][7]
|
||||
|
||||
Press Ctrl+H to show the hidden files and **open .hidden file** for editing. **Add the name of the files or folders in separate lines**. Keep in mind that it doesn’t take absolute or relative path. Your desired **files and folders should be in the same location as this special .hidden file**.
|
||||
|
||||
Here’s a sample which I used to hide the cpufetch directory and pcloud file without renaming them:
|
||||
|
||||
```
|
||||
pcloud
|
||||
cpufetch
|
||||
```
|
||||
|
||||
Press Ctrl+H again to hide the .hidden files again.
|
||||
|
||||
Now, **close your file explorer and start it again**. You won’t see the files and directories mentioned in the .hidden file anymore.
|
||||
|
||||
If you want to see them again, press Ctrl+H keys.
|
||||
|
||||
When you don’t want the files hidden anymore, remove their name from the .hidden file or remove .hidden file altogether.
|
||||
|
||||
### Bonus Trivia: The hidden files ‘feature’ was actually a bug
|
||||
|
||||
Do you know that this ‘feature’ to hide a file by adding a . at the beginning of the file name was [actually a bug][8]?
|
||||
|
||||
In the early UNIX days, when the filesystem was created, the . (current directory) and .. (parent directory) files were added for ease of navigation.
|
||||
|
||||
As these special . and .. files had no real data in them, a new ‘feature’ was added to the ls command.
|
||||
|
||||
The feature was to check the first character of a filename and if it’s a dot (.), it was no longer displayed with the ls command.
|
||||
|
||||
That worked for the . and .. files but it introduced a ‘bug’ where any filename starting with . was hidden from the output of the ls command.
|
||||
|
||||
This bug turned into a feature as programmers like it for ‘hiding’ their config files. The ls command was probably modified later to add options to display hidden dot files.
|
||||
|
||||
The same convention gets followed in Linux as Linux was modeled after UNIX.
|
||||
|
||||
### Conclusion
|
||||
|
||||
I have discussed creating files that are hidden from the normal view. If you want to create secret files or folders that cannot be accessed by other people, you should encrypt them. I have written about [locking folders with passwords in Linux][9]. It’s a bit old article but it may still work.

在 Linux 中用非重命名的方法隐藏文件和文件夹
|
||||
======
|
||||
简介：这篇面向初学者的文章探讨了在 Linux 中如何在普通视图中隐藏文件和文件夹。图形用户界面和命令行方法都有所涉猎。
|
||||
|
||||
有时你需要在 Linux 中隐藏文件。
|
||||
|
||||
不要误会，我不是指那些你不想让你的家人看到的“特殊文件”。尽管你可以隐藏这些特殊文件，但更好的办法还是用密码锁定它们以提供额外的保护。
|
||||
|
||||
回到隐藏文件的话题。 **名称以 `.` 开头的任何文件或文件夹在 Linux 中是“隐藏的”。**
|
||||
|
||||
Linux 有很多这样的文件和文件夹，在普通视图中它们是隐藏的。这些主要是系统和程序所需的配置文件。
|
||||
|
||||
用户通常不需要它们，因此它们在普通视图中是隐藏的，这样一来你就不会被许多看起来很奇怪的而不是你所创建的文件所淹没。
|
||||
|
||||
下图展示了我的主目录中隐藏的文件和文件夹。
|
||||
|
||||
![linux 普通视图][1]
|
||||
|
||||
![linux 显示隐藏文件][2]
|
||||
|
||||
如果你使用的是桌面版 Linux，你可以通过在文件管理器中按 Ctrl+H 快捷键来轻松 [查看隐藏文件][3]。在终端中，你可以使用 `ls -a` 命令显示隐藏文件和普通文件。
|
||||
|
||||
那么，如何在 Linux 中创建隐藏文件呢？你只需用一个在命名的时候加一个`.`前缀。就是这样。
|
||||
|
||||
### 在桌面版 Linux 里创建隐藏文件和文件夹（GUI 方法）
|
||||
|
||||
如果你使用的是文件管理器，在文件或文件夹上右键并选择重命名选项。现在你所要做的就是在文件名的开头添加一个 `.`。
|
||||
|
||||
当你以这种方式创建隐藏文件时，GNOME 的 Nautilus 文件管理器也会显示一个警告。
|
||||
|
||||
![ubuntu linux 隐藏文件][4]
|
||||
|
||||
你可以以相同的方式隐藏文件夹及其所有内容。
|
||||
|
||||
你可以按 Ctrl+H 键来显示隐藏文件。哦！我是多么的喜欢 [Ubuntu 中的键盘快捷键][5] 和我使用的任何其他程序或操作系统！
|
||||
|
||||
要使隐藏文件变回普通文件，只需再次重命名这些文件删掉文件名前缀的`.`即可。
|
||||
|
||||
### 在 Linux 终端创建隐藏文件和文件夹（CLI 方法）
|
||||
|
||||
如果你热衷于终端，你可以 [使用 mv 命令][6] 重命名文件。你只需在原始文件名的开头添加一个 `.`。
|
||||
|
||||
```
|
||||
mv filename .filename
|
||||
```
|
||||
|
||||
你可以使用以下命令显示隐藏文件：
|
||||
|
||||
```
|
||||
ls -la
|
||||
```
|
||||
|
||||
你也可以使用 `ls -lA`。这条命令不会显示点文件（`.` 和 `..`）。
|
||||
|
||||
### 额外提示：用非重命名的方法隐藏文件和文件夹（仅适用于 GUI）
|
||||
|
||||
你刚刚学了在 Linux 中隐藏文件。问题是你必须重命名文件，而这种操作不适用于所有的场合。
|
||||
|
||||
例如，在 Ubuntu 中，你会在目录中看到一个名为“snap”的文件夹。你不会使用它，但如果重命名它，你的 snap 应用程序将无法按预期工作。类似的情况是，在 Ubuntu 22.04（安装有 snap 版本的 Firefox）的 Downloads 目录下有一个 firefox.tmp 文件夹。
|
||||
|
||||
有一个巧妙的技巧可以在 Linux 桌面中使用。它应该可以在 Nemo、Thunar、Dolphin 等各种文件管理器下工作，但我不能保证。它确实适用于 GNOME 的 Nautilus 文件管理器。
|
||||
|
||||
因此，你在这里所做的是在你想要隐藏的文件或文件所在的目录中创建一个名为 `.hidden` 的新文件。
|
||||
|
||||
![在 Linux 中隐藏文件的另一种方法][7]
|
||||
|
||||
按 Ctrl+H 显示隐藏文件并 **打开 .hidden 文件** 进行编辑。**在单独的行中添加文件或文件夹的名称**。注意不能使用绝对或相对路径。你想要隐藏的**文件和文件夹应与此特殊 .hidden 文件** 位于同一路径下。
|
||||
|
||||
这是我以不重命名的方式隐藏 `cpufetch` 目录和 `pcloud` 文件的示例：
|
||||
|
||||
```
|
||||
pcloud
|
||||
cpufetch
|
||||
```
|
||||
|
||||
按 Ctrl+H 以再次隐藏 `.hidden` 文件。
|
||||
|
||||
现在，**关闭你的文件资源管理器并重新启动它**。你将不会再看到 .hidden 文件中提到的文件和目录。
|
||||
|
||||
如果你想再次查看它们，请按 Ctrl+H 键。
|
||||
|
||||
如果你不想再隐藏文件，请从 .hidden 文件中删除其名称或完全删除 .hidden 文件。
|
||||
|
||||
### 额外琐事：隐藏文件“功能”实际上是一个 bug
|
||||
|
||||
你知道吗？在文件名的开头添加一个 `.` 来隐藏文件的`功能`[实际上是一个 bug][8]？
|
||||
|
||||
在早期的 UNIX 时代，当创建文件系统时，`.`（当前目录）和 `..`（父目录）文件被添加以方便导航。
|
||||
|
||||
由于这些特殊的 `.` 和 `..` 文件中没有实际数据，因此给 `ls` 命令添加了一个新的“功能”。
|
||||
|
||||
该功能是检查文件名的第一个字符，如果它是一个点 (.)，则不再使用 ls 命令显示。
|
||||
|
||||
这对隐藏 `.` 和 `..` 文件有效，但它引入了一个 `bug`：`ls` 命令的输出会隐藏任何文件名以 `.` 开头的文件。
|
||||
|
||||
这个 bug 变成了一个功能，因为程序员喜欢它来“隐藏”他们的配置文件。`ls` 命令可能后来被修改为添加显示隐藏点文件的选项。
|
||||
|
||||
Linux 遵循相同的约定，因为 Linux 是以 UNIX 为原型开发的。
|
||||
|
||||
### 结论
|
||||
|
||||
我讨论了如何从普通视图中创建隐藏文件。如果要创建让其他人无法访问的机密文件或文件夹，则应对其进行加密。我曾经写过 [在 Linux 中使用密码锁定文件夹][9]。这是一篇有点儿旧的文章，但它可能仍然有效。
|
||||
|
||||
我希望你喜欢这个简单的话题并学到新的东西。发布你的评论让我知道你的想法吧。
