GNUScreen: Splitting, Unsplitting, and Re-splitting Screens with Keyboard Shortcuts
In this article, we will explore the concept of screen splitting in GNU Screen, a terminal multiplexer that allows users to manage multiple terminal sessions within a single window. We will cover the basics of splitting and unsplitting screens, as well as re-splitting screens using keyboard shortcuts. By the end of this article, you will have a solid understanding of how to use these features to improve your terminal management skills.
Screen Splitting
Screen splitting is the process of dividing a single screen into multiple regions, each displaying a separate terminal session. This feature is particularly useful when working with multiple programs or processes simultaneously, as it allows you to view and interact with them side-by-side without the need to switch between windows or use multiple terminals.
To split the screen in GNU Screen, use the Ctrl+a + S keyboard shortcut. This will split the current region into two equal parts, with the new region displaying a blank terminal session.
Unsplitting Screens
Unsplitting, or closing, a screen region is the process of removing a split region and returning the screen to its previous state. To unsplit a screen region in GNU Screen, use the Ctrl+a + Q keyboard shortcut.
It is important to note that unsplitting a region will focus the current session in the remaining region. If you need to focus a different session, you will need to use the appropriate keyboard shortcut to switch to it.
Re-splitting Screens
Re-splitting a screen is the process of splitting a region that has already been split. This feature is useful when you need to view multiple sessions side-by-side, but do not have enough regions to do so.
To re-split a screen region in GNU Screen, use the Ctrl+a + S keyboard shortcut while in the region you wish to split. This will split the region into two equal parts, with the new region displaying a blank terminal session.
Keyboard Shortcuts
The following table summarizes the keyboard shortcuts covered in this article:
| Action | Keyboard Shortcut |
|---|---|
| Split screen | Ctrl+a + S |
| Unsplit screen | Ctrl+a + Q |
| Re-split screen | Ctrl+a + S (while in a split region) |
In this article, we covered the basics of screen splitting, unsplitting, and re-splitting in GNU Screen. By using these features, you can improve your terminal management skills and work more efficiently with multiple terminal sessions.
