Linux, by default, hides many of the sensitive system files. Hidden files are usually system or application files, concealed to prevent accidental changes.

This guide will show you how to display and work with hidden files in Linux.

 How to View & Hide Files and Directories in Linux


  • A system running Linux
  • Access to a terminal window / command line (optional)

Note: Some directories require administrator, root, or sudo privileges to access. Depending on the files you want to access, you may need to switch users or use the sudo command.

How to Show Hidden Files

Show Hidden Files From the Command Line

To display all the files in a directory, including hidden files, enter the following command:

ls –a

The ls command lists the contents of the current directory. The –a switch lists all files – including hidden files.

To list regular and hidden files in a different directory than your current working location:

ls –a /etc

Replace /etc with any other directory.

Show Hidden Files in a Graphical Interface (GUI)

There’s a simple method to show hidden files if you’re more comfortable working in Gnome (or any other graphical interface).

1. First, browse to the directory you want to view.

2. Then, press Ctrl+h.

If Ctrl+h doesn’t work, click the View menu, then check the box to Show hidden files.

Note: Ctrl+h works in newer Ubuntu and CentOS environments. If you’re running an older or different version, it may not work.

How to Hide Files

Hide File or Directory Using the Linux Command Line

To mark a file as hidden, use the mv (move) command.

1. First, create a test file. Use the touch command to create an empty test.txt file:

touch test.txt

create a test file

2. Then, hide the file by moving it under a new filename. The period (.) at the beginning of the new filename indicates that it’s hidden:

mv test.txt .test.txt

3. To verify the file is now hidden, display the contents of the current directory:


4. Now, list the contents, including hidden files:

ls –a

You should see test.txt in the second listing.

Note: The process is entirely the same for directories. Use the mv command with a period (.) at the beginning of the new directory name.

Hide a File in a Graphical Interface (GUI)

You can also mark a file as hidden using a graphical interface.

1. Right-click the file you want to hide.

2. Then, select Rename.

3. Make the file hidden by placing a period at the beginning of the filename.

How to Create Password-Protected Hidden Files

Create Password-Protected, Hidden File From the Command Line

1. To create a hidden and password-protected archive file from the command line, start by creating a new text file:

touch test2.txt

2. Next, compress and encrypt that file:

zip ––encrypt test2.txt

3. You’ll be asked to enter and confirm a password for the file.

4. Then, use the ls command – you should see in the file list.

Encrypting a file requires more steps in the graphical version of Linux.

1. Start by opening the File Manager to your home directory.

2. Right-click an empty area, then click New Folder (a folder and a directory are the same things).

3. Name the folder test3 and click Create.

4. Next, click Activities > Search > type archive manager > launch the Archive Manager.

5. Drag and drop the new test3 folder into the Archive Manager window.

You should now be able to show and hide hidden files in Linux. These commands can be especially useful if you need to find configuration files.

Also, you can find web browser data, certain application caches, and logs stored in hidden files.
