Question

How can I permanently enable line numbers in IntelliJ IDEA?

Answer 1

In Intellij 13 the layout has changed, the Settings button can only be found in File -> Settings and not in the toolbars, and from there you follow the same steps: Editor -> Appearance -> Show line numbers, or search for Line numbers in the Settings search input.

Answer 2

For IntelliJ 20.1 or above, on Mac OSX:

IntelliJ IDEA -> Editor -> General -> Appearance -> Show line numbers

Point to be noted: Always look for Editor

For shortcut:

⌘ + ⇧ + A (command + shift + A)

type

and click on the pop up to turn on Show line numbers and you are good to go.

Answer 3

The question is obviously well answered already, but since IJ 13 you can enable line numbers in 2 seconds flat:

1. Press shift twice
2. Type "line number"
3. The option shows in the menu and press enter to enable/disable.

Et voila ;)

Answer 4

Android Studio 1.3.2 and on, IntelliJ 15 and on

Global configuration

Current editor configuration

First way: View -> Active Editor -> Show Line Numbers (this option will only be available if you previously have clicked into a file of the active editor)

Second way: Right click on the small area between the project's structure and the active editor (that is, the one that you can set breakpoints) -> Show Line Numbers.
