How can I permanently enable line numbers in IntelliJ?

 

我如何在IntelliJ IDEA中永久启用行号？

IntelliJ 14.X Onwards

From version 14.0 onwards, the path to the setting dialog is slightly different, a General submenu has been added between Editor and Appearance as shown below

IntelliJ 8.1.2 - 13.X

From IntelliJ 8.1.2 onwards, this option is in File | Settings 1. Within the IDE Settings section of that dialog, you'll find it under Editor | Appearance.

  • On a Mac, these are named IntelliJ IDEA | Preferences...

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

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

    Et voila ;)

    There's another way, and even quicker (works for me in version 10.5)

    Simply right click on the place where the line-numbers should be, and there you'll see a small menu.

    then, mark the "Show Line Numbers" option.

    Please note that this only works on a per-file basis, however. Enjoy.
