tmux Tutorial

A very useful tool.

Create new session:

tmux new -s radu-root
tmux new -s radu-sqlplus
tmux new -s radu-work

To dissconect from a session you are already in, I use Ctrl+b followed by pressing the d key.

To re-attach to a session and continue where you left you need to figure out which session you want to attach to first. List the currently running sessions by using

# tmux ls
import: 1 windows (created Wed Feb 15 08:49:22 2023) [210x45] (attached)

To re-attach the session called import:

# tmux attach -t import

Command prefix

An important concept is the command prefix which is basically a prefix that should be typed so what follows after is understood as a tmux command and not a command for the shell. By default, the prefix combination is ctrl+b. The default value can be customized if needed.

Working with panes

It is possible to split the screen into several panes:

In order to split vertically, one can use the combination PREFIX+%.

To split horizontally, the combination PREFIX+” would do the trick.

To kill a pane, there are different options:

• Type exit in the relevant pane
• Type PREFIX+x. This option will require confirmation:
