 Screen is deprecated into Redhat, now replaced by **TMUX**
-https://doc.ubuntu-fr.org/tmux
+https://www.redhat.com/sysadmin/introduction-tmux-linux
+TMUX is a terminal using a background session, so you can run long process without being disconnected from TIMEOUT (TMOUT)
+<cli prompt='$'>
+$ tmux
+</cli>
+{{linux:tmux01.png?500}}
+**For HELP**
+  You can now run your first Tmux command. For example, to get a list of all commands, you would type:
+  Ctrl+b ?
+To start using tmux, type tmux on your terminal. This command launches a tmux server, creates a default session (number 0) with a single window, and attaches to it.
+You can detach from your tmux session by pressing **Ctrl+B** then **D**. Tmux operates using a series of keybindings (keyboard shortcuts) triggered by pressing the "prefix" combination. By default, the prefix is Ctrl+B. After that, press D to detach from the current session.
+List you background sessions
+<cli prompt='$'>
+$ tmux ls
+: 1 windows (created Sat Aug 27 20:54:58 2022)
+</cli>
+Connect to session number 0 (or maybe attach-session ?)
+<cli prompt='$'>
+$ tmux attach -t 0
+</cli>
+As you can see, the command continued to run and print messages on the screen. You can type Ctrl+C to cancel it.
+Satart a session with specific name
+  tmux new -s Session1
+TMUX options
+  * Ctrl+B D — Detach from the current session.
+  * Ctrl+B % — Split the window into two panes horizontally.
+  * Ctrl+B " — Split the window into two panes vertically.
+  * Ctrl+B Arrow Key (Left, Right, Up, Down) — Move between panes.
+  * Ctrl+B X — Close pane.
+  * Ctrl+B C — Create a new window.
+  * Ctrl+B N or P — Move to the next or previous window.
+  * Ctrl+B 0 (1,2...) — Move to a specific window by number.
+  * Ctrl+B : — Enter the command line to type commands. Tab completion is available.
+  * Ctrl+B ? — View all keybindings. Press Q to exit.
+  * Ctrl+B W — Open a panel to navigate across windows in multiple sessions.
+then toggle the mouse on (or off) with the command set -g mouse.
+Using colors:
+  Change the status bar background color: set -g status-bg cyan
+  Change inactive window color: set -g window-status-style bg=yellow
+  Change active window color: set -g window-status-current-style bg=red,fg=white
+=== Configure tmux ===
+You can change the tmux configuration permanently by modifying the tmux configuration file. By default, this file is located at $HOME/.tmux.conf.
+For example, the default prefix key combination is Ctrl+B, but sometimes this combination is a little awkward to press, and it requires both hands. You can change it to something different by editing the configuration file. I like to set the prefix key to Ctrl+A. To do this, create a new configuration file and add these lines to it:
+<cli prompt='$'>
+$ cat $HOME/.tmux.conf
+# Set the prefix to Ctrl+a
+set -g prefix C-a
+# Remove the old prefix
+unbind C-b
+# Send Ctrl+a to applications by pressing it twice
+bind C-a send-prefix
+</cli>
+Another example
+<code>
+# Improve colors
+set -g default-terminal 'screen-256color'
+# Set scrollback buffer to 10000
+set -g history-limit 10000
+# Customize the status line
+set -g status-fg  green
+set -g status-bg  black
+</code>
+=== Screen ===
+//Only for historic info//
 Screen (command) is a background terminal, you can start applications in background, quit your windows and recall your session.
