Introduction

When working on a remote server, it is essential to keep sessions active even if the terminal disconnects. The Screen tool allows users to attach and detach console sessions, ensuring that processes continue running without interruption.

If you manage a server on a reliable hosting platform or use a secure VPS, Screen is a valuable tool to enhance efficiency and maintain uninterrupted workflow.

What is Screen?

Screen is a terminal multiplexer that enables multiple sessions within a single terminal. It helps keep processes running in the background, even after closing the main terminal. This is particularly useful for long-running tasks or unstable SSH connections.

Why Use Screen?

  • Keeps sessions active: Processes continue running even if the connection is lost.
  • Manages multiple sessions: Users can operate different terminal sessions within one window.
  • Supports collaboration: Multiple users can access the same session.
  • Enhances efficiency: Ideal for long updates, installations, and downloads on a server.

How to Use Screen Effectively

Starting a Session

Users can create a new session to run processes without worrying about interruptions.

Detaching a Session

If a user needs to disconnect from the terminal while keeping tasks running, they can detach the session and return to it later.

Listing Active Sessions

For managing multiple sessions, users can check ongoing sessions to reattach to the required one.

Reattaching a Detached Session

After detaching, users can reconnect to their active session and continue their work.

Closing a Session

Once tasks are complete, users can terminate the session to free up system resources.

Best Practices for Using Screen

  • Organize sessions efficiently by naming them to easily track multiple processes.
  • Ensure persistent sessions for critical operations that must continue running even after a system reboot.
  • Use multiple windows within a session to multitask and improve productivity.

Conclusion

Screen is an essential tool for anyone managing remote servers, ensuring that processes run continuously without session loss. Whether using a secure VPS or a shared hosting environment, Screen improves productivity and streamlines command-line operations.
