Using Tmux
Terminal multiplexers, like tmux or Screen, are great utilities for expanding a standard Linux terminal's features, like having multiple windows within one terminal and jumping between them. Let's see some examples of using tmux, which is the more common of the two. If tmux is not present on our Linux system, we can install it with the following command:
Once we have tmux, we can start it by entering tmux as our command:
The default key to input tmux commands prefix is [CTRL + B]. In order to open a new window in tmux, we can hit the prefix 'i.e. [CTRL + B]' and then hit C:
We see the numbered windows at the bottom. We can switch to each window by hitting the prefix and then inputting the window number, like 0 or 1. We can also split a window vertically into panes by hitting the prefix and then [SHIFT + %]:
We can also split into horizontal panes by hitting the prefix and then [SHIFT + "]:
We can switch between panes by hitting the prefix and then the left or right arrows for horizontal switching or the up or down arrows for vertical switching. The commands above cover some basic tmux usage. It is a powerful tool and can be used for many things, including logging, which is very important during any technical engagement.
