Below are given the examples on how to start IDE from the command line on different OS. You should substitute the product name and version/build number in path according to your installation.

- Windows

- macOS

- Linux

Windows

cd "C:\Program Files\JetBrains\IntelliJ IDEA 2020.1\bin"
.\idea.bat

If you use Toolbox (see this comment on how to quickly find IDE path):

cd "%LOCALAPPDATA%\JetBrains\Toolbox\apps\IDEA-U\ch-2\201.4865.12\bin"
.\idea.bat

macOS

To get additional debug logging for troubleshooting launcher issues, set the environment variable before starting the IDE:

export IDEA_LAUNCHER_DEBUG=true

cd /Applications
./IntelliJ\ IDEA.app/Contents/MacOS/idea

If you use Toolbox (see this comment on how to quickly find IDE path):

cd /Users/<username>/Library/Application\ Support/JetBrains/Toolbox/apps/IDEA-U/ch-1/201.4865.12
./IntelliJ\ IDEA\ 2020.1.app/Contents/MacOS/idea

Linux

Change directory to “bin” under the IDE installation path and run:

./idea.sh

If you use Toolbox (see this comment on how to quickly find IDE path):

cd ~/.local/share/JetBrains/Toolbox/apps/IDEA-U/ch-2/201.4865.12
./idea.sh
