Tmux is available for a variety of operating systems, including Linux, macOS, and Windows.

To install Tmux on Ubuntu, you can use the following command:

sudo apt-get install tmux

This will install Tmux on your system. Once installed, you can start using it by running the tmux command.

If you encounter any issues during the installation process, you can refer to the Tmux documentation or seek help from the Tmux community.

In summary, to install Tmux on Ubuntu, use the sudo apt-get install tmux command.

Here are some of the useful commands:

• Open a new session

To open a new session and name it, use the following command:

Copy

tmux new -s session_name

Replace session_name with the name you want to give to the session. This will create a new Tmux session with the specified name.

Then, to attach to the newly created session, use the command:

Copy

tmux attach -t session_name

This will attach you to the session you just created and named.

• attach to the last session

tmux -a attaches to the last session automatically. If there is no previous session, it creates a new session.
