Tmux Cheat Sheet
January 26, 2021 | by Stefano Lanaro |
Introduction
Tmux is an open-source terminal multiplexer for Unix-like operating systems. It allows multiple terminal sessions to be accessed simultaneously in a single window.
It is useful for running more than one command-line program at the same time. It can also be used to detach processes, allowing remote sessions to remain active without being visible.
Cheat Sheet
Tmux comes with a lot of built-in commands, although these are the main ones I use while performing day-to-day operation:
Command

tmux new -s stef
Start a new session and call it stef
tmux kill-session -t stef
Kill the stef session
tmux attach-session -t stef
Attach o the stef session
[CTRL+B] + $

Conclusion
Tmux is a phenomenal that can help massively improve productivity by allowing to have any number of split panes, windows and sessions that can allow to run several tasks simultaneously.
It is also a lot more configurable than a normally terminal and it has really useful functionalities like the ability to log every command automatically to a log file.
