Tmux is one of the most useful tool when it comes to using a linux terminal.

Tmux is a terminal multiplexer, it allows a user to access multiple terminals (or windows), each running a separate program, while providing a single screen to work on. Tmux is useful for running more than one command-line program at the same time, increasing productivity and the way you work.

You can create a new tmux session by using the tmux new command when you are outside of tmux environment. But, in case you are already in a tmux session and want to create a new session from within, it can be done seamlessly by using the below ways-

Create a nested tmux session

Creating a new tmux session from within another tmux session is easy, you just have to run the following command-

Prefix
:new

By default the prefix is Ctrl-B, so you can create a nested tmux session using-

Ctrl-B
:new

Create a nested tmux session with a name

Creating a new tmux session from within another tmux session is easy, you just have to run the following command-

Prefix
:new -s <name>

By default the prefix is Ctrl-B, so you can create a nested tmux session using-

Ctrl-B
:new -s <name>

For example, if you want to name your new session myaws, your keyboard shortcut and command will look like-

Ctrl-B
:new -s myaws

You can quit a tmux session and then create a new tmux session as well, this will also help you create a tmux session.
