sudo yum install -y tmux

This command installs ‘tmux’ on your system.

Installing ‘tmux’ with Pacman

If you’re using an Arch-based distribution like Manjaro, you can use the Pacman package manager to install ‘tmux’. Here is the command:

sudo pacman -S tmux

This command installs ‘tmux’ using the Pacman package manager.

In the next section, we’ll delve into more advanced installation methods of the ‘tmux’ command.

Installing ‘tmux’ from Source

If your Linux distribution does not include ‘tmux’ in its standard repositories, or you need a different version than the one available, you can install ‘tmux’ from its source code. Here’s how you do it:

sudo apt-get install -y libevent-dev libncurses-dev make
wget https://github.com/tmux/tmux/releases/download/3.2a/tmux-3.2a.tar.gz
tar xvzf tmux-3.2a.tar.gz
cd tmux-3.2a
./configure && make
sudo make install

This script first installs the necessary dependencies, then downloads the ‘tmux’ source code from the official GitHub repository, unpacks the tarball, compiles the source code, and finally installs it.

Installing Different Versions of ‘tmux’

Different versions of ‘tmux’ may have different features, bug fixes, or compatibility with different systems. Here’s how to install different versions of ‘tmux’.

From Source

To install a specific version from source, you only need to replace the version number in the download URL from the previous example.

Using Package Managers

APT

On Debian-based systems, you can check the available versions with the following command:

apt-cache policy tmux

You can then install a specific version with:

sudo apt-get install tmux=version

Replace ‘version’ with the version number you want to install.

YUM

On Red Hat-based systems, you can list available versions with:

yum --showduplicates list tmux

You can then install a specific version with:

sudo yum install tmux-version

Replace ‘version’ with the version number you want to install.

Version Comparison

Using ‘tmux’ and Verifying the Installation

Using ‘tmux’

Once installed, you can start a new ‘tmux’ session with the ‘tmux’ command. You can then create new windows with ‘Ctrl-b c’, switch between them with ‘Ctrl-b n’ and ‘Ctrl-b p’, and split windows into panes with ‘Ctrl-b %’ and ‘Ctrl-b “‘.

Verifying the Installation

You can verify that ‘tmux’ is correctly installed and find out its version with the following command:

tmux -V

This command should output the version number of ‘tmux’.

Alternative Methods for Managing Terminal Sessions

While ‘tmux’ is a powerful tool for managing terminal sessions, it’s not the only one available. There are alternative methods, such as the ‘screen’ command, which also offer robust features for terminal session management.

The ‘screen’ Command

Similar to ‘tmux’, ‘screen’ is a full-screen window manager that multiplexes a physical terminal. Here’s how you can install it on a Debian-based system:

sudo apt-get install screen

And here’s how to start a new ‘screen’ session:

screen

You can detach from the session using ‘Ctrl-a d’ and reattach with ‘screen -r’.

# To detach
Ctrl-a d

# To reattach
screen -r

Comparing ‘tmux’ and ‘screen’

Both ‘tmux’ and ‘screen’ are powerful tools, but they have their differences. Here’s a comparison of their key features:

While ‘tmux’ offers more features and customization options, ‘screen’ might be sufficient for simpler tasks or on systems where ‘tmux’ is not available.

In the end, the choice between ‘tmux’ and ‘screen’ depends on your specific needs and preferences. We recommend trying both and seeing which one fits your workflow best.

Troubleshooting ‘tmux’ Installation and Usage

Even with the best of preparations, you may encounter issues when installing or using ‘tmux’. Here are some common problems and their solutions.

‘tmux’ Not Found

If you get a ‘tmux: command not found’ error, it’s likely that ‘tmux’ isn’t installed or that it’s not in your PATH. First, check if ‘tmux’ is installed:

which tmux

If this command doesn’t return anything, ‘tmux’ isn’t installed. Refer to the installation instructions above.

If ‘tmux’ is installed but not in your PATH, you’ll need to add it. The process for this varies depending on your shell, but here’s how you can do it in bash:

echo 'export PATH=$PATH:/path/to/tmux' >> ~/.bashrc
source ~/.bashrc

Replace ‘/path/to/tmux’ with the actual path to the ‘tmux’ executable.

‘tmux’ Sessions Disappearing After Reboot

By default, ‘tmux’ sessions are not saved across reboots. If you want to persist your sessions, you can use a plugin like tmux-resurrect.

‘tmux’ Not Working Correctly After an Upgrade

If you’ve upgraded ‘tmux’ and it’s not working correctly, it’s possible that there are compatibility issues with your configuration file. Try moving your ‘~/.tmux.conf’ file to a backup location and see if the problem persists.

mv ~/.tmux.conf ~/.tmux.conf.bak
tmux

If ‘tmux’ works correctly, the issue is with your configuration. You can either fix the problematic options or start with a new configuration.

These are just a few examples of the issues you might encounter when using ‘tmux’. Remember, when in doubt, refer to the ‘tmux’ man page (man tmux) or seek help from the Linux community.

Understanding Terminal Multiplexing

Terminal multiplexing is a method that allows multiple terminal sessions to be created, accessed, and controlled from a single screen. ‘tmux’, short for Terminal Multiplexer, is one such tool that allows this.

The Need for Terminal Multiplexing

When working with Linux, you often find yourself needing to run multiple commands or scripts simultaneously. You might be tempted to open multiple terminal windows, but this can quickly become unmanageable. This is where terminal multiplexing comes in.

With a terminal multiplexer like ‘tmux’, you can run multiple terminal sessions within a single window. You can switch between them, split them into panes, and even detach them and reattach them later.

tmux new-session -s my_session

This command creates a new ‘tmux’ session named ‘my_session’. You can detach from the session with ‘Ctrl-b d’ and reattach with ‘tmux attach-session -t my_session’.

# Detach from the session
Ctrl-b d

# Reattach to the session
tmux attach-session -t my_session

The Power of ‘tmux’

‘tmux’ is more than just a terminal multiplexer. It’s a powerful tool that can significantly boost your productivity. With ‘tmux’, you can:

• Run multiple commands simultaneously without needing to open multiple SSH connections.
