1. prefix + s show all sessions
2. prefix + d detach dession
3. prefix + $ rename session
4. prefix + ( move to previous session
5. prefix + ) move to next session

Using Shortcut

prefix + $ rename current session

Using tmux comand

:rename-sessin [-t current-name] [new-name]

Using shell command

1

tmux rename-sessin [-t current-name] [new-name]

sudo osascript -e "set Volume 10" # the maximum
sudo osascript -e "set Volume 0" # mute

Note: We cam set the value between 0 and 10.

tmux ls # ls all active sessions

tmux ls is actually a short form of tmux list-sessions. Compared to list-sessions, ls is much shorter so I recommend using tmux ls always.

prefix + C-D detach current session
