If you’ve ever felt stuck managing multiple terminal windows while working on a server, tmux is here to rescue you! tmux is a terminal multiplexer, allowing you to open, split, and manage multiple terminal sessions in one window. Think of it as having a superpower to juggle tasks on your terminal effortlessly. 💪

Who Introduced Me to TMUX? 🤝

I was introduced to tmux by Advitya Sharma, a fellow developer and a React expert. His enthusiasm for efficient workflows inspired me to dive into this amazing tool. Thank you, Advitya, for opening up this world of productivity! 🚀

Why Should You Learn TMUX as a Beginner?

As you start learning about servers and exploring terminal-based tools, tmux can help you:

1. Keep Sessions Active: Detach from a session and reconnect without losing progress.

2. Monitor Logs: Check multiple logs simultaneously in split panes.

3. Run Long Commands: Start long-running tasks and revisit them later.

4. Work Remotely: Reconnect to your work on a server, even after disconnection.

Basic TMUX Commands 🛠️

1. Create a New Session

Start your first tmux session:

tmux

This opens a fresh tmux session where you can begin your work.

2. Detach and Reattach to Sessions

Working on a server and need to log off without interrupting tasks?

• Detach from a Session:

    Ctrl+b d
  

• Reattach to the Session:

    tmux attach
  

3. List Active Sessions

If you have multiple sessions running, check them with:

tmux ls

4. Rename Your Session

Give your session a meaningful name to stay organized:

Ctrl+b $

How to Exit or Kill a TMUX Session 🛑

When you’re done with your work in tmux, here’s how to properly exit or kill a session:

1. Exit a Session

• Exit the Current Pane or Window:

    exit
  

  This will close the current pane or window you’re in. If it’s the last window, it will terminate the session.

2. Kill a Session Directly

• Kill a Specific Session:

    tmux kill-session -t <session_name>
  

  Replace <session_name> with the name of your session.

• Kill All Sessions:

    tmux kill-server
  

  This will terminate all running tmux sessions.

3. Use a Shortcut to Kill a Window

If you’re inside tmux and want to close a specific window:

Ctrl+b &

tmux will prompt you to confirm the action.

Using TMUX to Learn About Servers 🌐

Here’s how you can use tmux while exploring servers:

1. Monitor Server Logs

If you’re learning about web servers like Apache or Nginx, use tmux to monitor logs.

• Open a tmux session and run:

    tail -f /var/log/nginx/access.log
  

• Split the pane and monitor error logs:

    Ctrl+b %
    tail -f /var/log/nginx/error.log
  

2. Run Commands Without Losing Progress

While exploring servers, you might need to run updates or install packages:

• Start the task:

    sudo apt update && sudo apt upgrade
  

• Detach from the session if needed:

    Ctrl+b d
  

• Reattach later to check the progress:

    tmux attach
  

3. Practice File and Directory Management

Learning to navigate server directories? Use tmux to practice commands side by side:

• Split the pane vertically:

    Ctrl+b "
  

• Use one pane to create directories:

    mkdir my_server_files
  

• Use the other pane to view them:

    ls -l
