Invoking IntelliJ IDEA from the command line

On OS X or UNIX:

• Make sure IntelliJ IDEA is running.
• On the main menu, choose Tools > Create Command-line Launcher. The dialog box Create Launcher Script opens, with the suggested path and name of the launcher script. You can accept default, or specify your own path.
• Make notice of it, as you'll need it later. Outside of IntelliJ IDEA, add the path and name of the launcher script to your path.

On Windows:

• Specify the location of the IntelliJ IDEA executable in the Path system environment variable. In this case, you will be able to invoke the IntelliJ IDEA executable and other IntelliJ IDEA commands from any directory.
