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
