Usage

After installation, you can start using iTerm2 right away. Launch it from your Applications folder or use Spotlight Search. The interface is user-friendly, making it easy to navigate.

To open a new tab, use the shortcut Command (⌘) + T. To split panes, use Command (⌘) + D for a vertical split and Command (⌘) + Shift + D for a horizontal split.

Customization

One of the standout features of iTerm2 is its extensive customization options. Here’s how you can personalize your terminal:

Themes: Choose from various themes to change the look and feel of your terminal. You can find themes online or create your own.
Profiles: Create multiple profiles for different tasks. Each profile can have its own settings, such as colors, fonts, and window size.
Keyboard Shortcuts: Customize keyboard shortcuts to streamline your workflow. This feature allows you to assign specific actions to keys that suit your preferences.
Transparency: Adjust the transparency of your terminal window. This can help reduce distractions by allowing you to see your desktop or other applications behind the terminal.

Integration with tmux

iTerm2 works seamlessly with tmux, a terminal multiplexer. This integration allows you to manage multiple terminal sessions within a single window. Here’s how to set it up:

Install tmux if you haven’t already. You can use Homebrew:
```
brew install tmux
```
Start a new tmux session by typing:
```
tmux
```
Use iTerm2’s split pane feature to create multiple panes within your tmux session. This setup enhances your productivity by allowing you to view multiple processes at once.

Scripting with Python

iTerm2 supports scripting with Python, enabling advanced users to automate tasks. Here’s a simple example to get you started:

Open iTerm2 and navigate to Preferences > Profiles > [Your Profile] > Command.
Set the command to run your Python script:
```
python3 /path/to/your/script.py
```
Save the settings. Your script will run every time you open that profile.

For more complex scripting, refer to the iTerm2 Scripting Documentation.
