Getting Began with Tmux

Tmux is a terminal multiplexer. It lets you work with more than one terminal classes steady now.


It may possibly be very easy to install and there a ton of guides already accessible, so I may per chance presumably merely no longer duvet it in this blog put up.

Tmux terminology

So, let us commence with the fundamentals.

tmux server (programm) > session > window > pane

The tmux server starts after working tmux. That you may work on associated classes, or detach them, so they speed in the background. Every server can own more than one classes, each and every session can own more than one windows, and we’re going to provide the chance to interrupt up a window in more than one panes. The pane is a routine terminal window on the end.


There are a range of use cases for it. Tmux makes is easy to separate initiatives in a great deal of windows or classes.

The prefix or lead and meta-key

The default prefix (or normally known as ‘lead’) is CTRL + b (or C-b) and it is mostly the commence of a tmux shortcut or to make use of a tmux snarl. In case you gaze something enjoy: Prefix + c, press CTRL + b, after which c. I purchase CTRL + s for instance. I could show how to alternate it in the subsequent portion.

As a aspect existing: you may per chance discover some shortcuts with a M in them. Here is the meta-key. It is miles ALT for Linux, I score CMD in MacOS, and barely even ESC. The meta-key’s no longer normally ragged, nonetheless price having a leer it up.

The config file

That you may temporarily alternate your tmux config by entering the environment:

Prefix + :set -g prefix C-s

This is capable of alternate the Prefix as we described it earlier than. Within the occasion you ought to create changes completely, edit the config file. On Linux, the config file is mostly in the house itemizing of the client ~/.tmux.conf. If there will not be any longer any config file, merely construct it, and restart tmux – or reload it (will show finally of this portion). Comely put set -g prefix C-s into the config file and tmux will use it after the restart.

There are many methods to customize tmux. Some examples: Vim-enjoy bindings for pane movements, enabling mouse enhance, surroundings keyboard shortcuts, and so forth.

The very best plot to reload the config file after changes is to make use of the following tmux snarl: Prefix + :source-file ~/.tmux.conf (alternate the trot accordingly).

Working with panes

As talked about earlier than, you may per chance ruin up a window in more than one panes. That you may ruin up the window vertically or horizontally as you will need and alternate it as indispensable as you would like. I may per chance presumably merely no longer duvet every little thing in this put up, nonetheless I could show you the bascis.

Ruin up horizontaly:
Prefix + %
Ruin up vertically:
Prefix + "
Transfer to some other pane:
Prefix + ARROW KEY
Convert the scorching pane steady into a brand original window:
Prefix + !
Close fresh pane:
Prefix + x

There are shortcuts for resizing, transferring panes spherical, and so forth, nonetheless those don’t seem to be that important for this primer.

Aspect existing: I real wrote about a separate put up about sending input to all panes inner a window. Be ecstatic to test it out here.

Working with windows

I purchase to separate my initiatives with windows in explain of classes, nonetheless real some desire.

Invent a brand original window:
Prefix + c
Rename fresh window:
Prefix + ,
Close fresh window:
Prefix + &
Change to subsequent window:
Prefix + n
Change to outdated window:
Prefix + p
Change to window by number:
Prefix + 09

Working with classes

Let me commence with a shortcut that I real learned currently.

Prefix + w

This affords you a short overview of all classes and windows and lets you swap rapid.

Expose all classes:
tmux ls
Prefix + s
Invent original session:
tmux new -s new-session
:new -s new-session
Rename session:
Prefix + $
Detach session (will be active in the background):
Prefix + d
Close a session:
tmux kill-session -t old-session
Join session:
tmux attach -t old-session
Transfer to subsequent session:
Prefix + )
Transfer to outdated session:
Prefix + (


This put up optimistically will can abet you to to commence with tmux. I could duvet more topics and components of tmux in some unspecified time in the future.

Any notes or questions? – Be ecstatic to reach out.
