How to Host Multiple Linux Terminals for Viewing and Collaboration with Wemux?


In software development, collaboration is key to success. Whether you're working on a small project or a large enterprise application, the ability to work together efficiently and effectively can make all the difference.

Collaborating with others allows you to combine your unique skills and expertise, leverage the strengths of your teammates, and develop high-quality software in less time. However, collaboration can be challenging when it comes to working with code.

Explanation of Wemux and its Benefits for Hosting Multiple Linux Terminals

Wemux is a powerful tool that allows you to host multiple Linux terminals for viewing and collaboration purposes. It's essentially a terminal multiplexer that enables multiple users to access the same terminal session simultaneously.

With Wemux, users can share their terminal output with others in real-time, which makes it an ideal solution for team environments. Wemux offers several benefits over traditional methods of collaboration.

First, it eliminates the need for everyone on the team to have access to the same server or code repository. Instead, developers can simply join a Wemux session from their own local machine and begin collaborating right away.

Setting Up Wemux

Installation instructions for Wemux on a Linux server

Before starting to use Wemux, the first step is installing it. The installation process of Wemux is very simple and straightforward, as it is available in most package managers.

For Debian (or Debian-based) systems, you can use the following command to install Wemux −

sudo apt-get update && sudo apt-get install wemux

After this command completes successfully, you will have Wemux installed on your system. For other systems like CentOS or RHEL, you can install Wemux using the following command −

sudo yum update && sudo yum install wemux 

Once again, after this command finishes successfully, you can enjoy all the features of this tool.

Configuration options for customizing Wemux settings

Wemux provides several configuration options that allow users to customize its behavior according to their preferences. Some of these options include setting a custom prefix key for sending commands to shared sessions or disabling mouse support when connected through SSH.

These configuration options are located in the `~/.wemux.conf` file which can be edited using any text editor. Opening this file will present users with various configuration variables that they can modify as needed.

For instance, if you want to change the default prefix key from `ctrl-b` to something else like `ctrl-a`, simply add the following line into your `~/.wemux.conf` file −

set -g prefix C-a 
unbind C-b bind C-a send-prefix 

Other customization options include changing pane colors or enabling/disabling certain features like pane syncing and user permissions.

Hosting Multiple Terminals with Wemux

Step-by-step guide to creating and joining sessions with multiple users

Once Wemux is installed and configured, hosting multiple terminals for collaboration is easy. First, the host user must create a new session by entering the following command −

wemux start [session-name]

This will create a new session with the specified name and automatically join it. Other users can then join the session by entering −

wemux join [session-name]

If there are already other users in the session, they will be able to see and interact with each other's terminals immediately upon joining. In addition, Wemux supports various options for customizing sessions.

For example, sessions can be created with read-only access or restricted access to certain users using the --readonly and --allow [user] flags respectively. These options allow for even more control over collaborative terminal sessions.

Overview of key features, such as pane syncing and user permissions

Wemux offers several key features that make it an ideal tool for collaborating on Linux terminals. One such feature is pane syncing, which allows all users in a session to see each other's terminal output in real time. This feature is particularly useful when working on code together or troubleshooting an issue as a team.

Advanced Features and Customization Options

Window Splitting

One of the more advanced features of Wemux is window splitting, which allows you to split a single terminal window into multiple panes. This feature can be incredibly useful for users who need to keep an eye on multiple processes or even collaborate with a team on different tasks within the same terminal session.

To use this feature, simply type "ctrl-b %" or "ctrl-b '" to split the current pane horizontally or vertically. Another helpful aspect of window splitting is that it allows you to resize and move individual panes as needed.

Customization Options: Color Schemes and Key Bindings

Another major benefit of Wemux is its customization options. Users can customize everything from color schemes to key bindings depending on their preferences. Changing the color scheme is as simple as modifying a configuration file and reloading your Wemux session; this makes it possible for users who find default colors difficult to read due to vision impairment or colorblindness.

Key bindings are another way users can improve their experience with Wemux by mapping frequently used actions to specific keys for easier access. For example, if you often switch between panes within your terminal session using "ctrl-b n" and "ctrl-b p", you could map these commands instead to something like "ctrl-b j" and "ctrl-b k" for faster switching.

Collaborating with Wemux: Best Practices

Now that you have a basic understanding of how Wemux works, it’s time to consider best practices for effective collaboration. To get the most out of your collaborative terminal session, it’s important to establish clear communication and make efficient use of panes. Here are some tips to help you collaborate effectively with Wemux.

Tips for Effective Collaboration

First and foremost, clear communication is key when collaborating with others using Wemux. Make sure everyone in the session understands what their role is in the project and what tasks they need to complete.

When communicating, be concise and specific about what you need from others. Another important tip for effective collaboration is making efficient use of panes.

Panes allow multiple users to work on different parts of the project simultaneously without interfering with each other’s work. It’s helpful to assign specific panes to individual users or groups so that everyone can easily access their assigned tasks.

Examples of Real-World Use Cases

Wemux is a powerful tool that can be used in many different real-world scenarios. One example might be a team working on software development projects together in remote locations.

With Wemux, developers can collaborate by sharing terminals and accessing each other's code without worrying about conflicting changes or broken code. In addition, Wemux is also a great tool for educational settings where students need to collaborate on programming assignments or group projects.

By using Wemux, students can share screens and work collaboratively without having to physically meet up in person. Effective collaboration requires clear communication and efficient use of panes when using Wemux.


Wemux is a powerful tool that can significantly improve collaboration for software development teams working with Linux servers. By enabling multiple users to view and control the same terminal session simultaneously, Wemux makes it easier to share knowledge, troubleshoot issues, and streamline workflows.

With features like pane syncing and user permissions, it's also possible to maintain privacy and control over who can access the shared session. In addition to its functionality, Wemux is relatively easy to set up and use.

With just a few simple commands, you can create or join a session and start collaborating with your team. And with customizable options for color schemes, key bindings, window splitting, and more, you can tailor the experience to fit your team's needs.
