tmux lets me keep manage multiple command line windows and shells inside a single terminal window. That’s fine in its own right, but the thing I really appreciate about tmux is it lets me leave long-running commands going in the background without worrying about
nohup or accidentally closing a background window.
I don’t start tmux by default, since I like occasionally starting a quick temporary terminal on a different window. But I can always access my tmux session quickly with an alias in my
tmux allows you to have multiple named sessions, which can be useful in shared environments, or when it’s being used for very long-running processes. But I prefer to just use it with a single session, and the alias provided will jump you directly into a single running session.:
alias tmuxs='tmux attach || tmux new-session'
I use the following config file (
# I use zsh by default set-option -g default-shell /bin/zsh # colorful set -g default-terminal "screen-256color" # Use C-z instead of C-b (personal preference) unbind C-b set -g prefix C-z bind C-z last-window bind z send-prefix set -g mouse on set -g history-limit 250000 setw -g alternate-screen on # Lower the escape timing from 500ms to 50ms for quicker response to scroll-buffer access. set -s escape-time 50 # Use | and - for horizontal/vertical window splitting unbind % bind | split-window -h bind - split-window -v # Refresh config with r bind-key r source-file ~/.tmux.conf \; display-message "~/.tmux.conf reloaded" # Fix titlebar set -g set-titles on # VIM mode set -g mode-keys vi # Avoid date/time taking up space set -g status-right '' set -g status-right-length 0
With that config, I mostly use the following commands to move around:
ctrl-z is the prefix key, used in combination with another key sequence to perform an action.
ctrl-z up/down/left/right arrow change the current pane based on the direction.
ctrl-z 0-9 change the current window based on the number.
ctrl-z - splits the screen vertically, creating a new pane.
ctrl-z | splits the screen horizontally, creating a new pane.
ctrl-z x closes the current pane.
ctrl-z c creates a new window.
