About this Hands-on Lab

Anyone using a text-based console or attaching to a remote Linux system via SSH needs to know about the `screen` command, what sessions are, and how to create them, use them, and exit or end them properly.

Learning Objectives

Successfully complete this lab by achieving the following learning objectives:

Initiate, Query, and Display `screen` Sessions

Start sessions, query their presence, and display or view the programs running in those screen sessions.

Detach from and Reattach to `screen` Sessions

Detach from a running session and its program contents, then reattach to the session either by default or by name.

Create and Query Detached Sessions

Start detached sessions with specific names, and query those sessions for information without having to attach to those sessions.

Name and Rename `screen` Sessions

Use specific naming for sessions to easily identify what they contain, including renaming sessions as they are running and fixing variable issues that would keep the session from functioning properly.

Exit from and End `screen` Sessions

Use more advanced techniques to send either keystrokes that are used to quit running session content programs, or send the session itself commands that cause it to exit or end.

Additional Resources

In this lab, you are a junior systems operator who needs to become more familiar with screen sessions. You need to use them to be more productive when you're restricted to a single TTY console or SSH session on a server in your enterprise.
