To permanently enable line numbers in IntelliJ IDEA, you can configure the IDE to display line numbers for all your projects and files. Here's how to do it:

  1. Open IntelliJ IDEA.

  2. Go to "File" > "Settings" (on Windows) or "IntelliJ IDEA" > "Preferences" (on macOS).

  3. In the Settings/Preferences dialog, navigate to "Editor" > "General" > "Appearance."

  4. In the "Appearance" section, check the "Show line numbers" option.


  5. Click the "Apply" button if it's enabled (on macOS) or "OK" (on Windows) to save the changes.

Now, line numbers will be permanently enabled for all your projects and files in IntelliJ IDEA.

Here's an example of how it looks with line numbers enabled:


Please note that these settings are IDE-wide, so they will apply to all your projects and files within IntelliJ IDEA. If you have multiple projects open, line numbers will be shown in all of them.
