tmux in 10 mins

This is also a good Intro to tmux. This is one of the sources from which this current document is adapted.

Ubuntu / Debian Linux Installation

Installation for Ubuntu is similar to Mac, except that we will be using the apt-get package manager that comes pre-installed. Note that we will have to run apt-get as sudo. This is because a user account won’t have enough privileges to install tmux, so sudo will allow us to install it as superuser.

  • Update apt-get to make sure we are on the latest and greatest:
    sudo apt-get update
  • Install tmux:
    sudo apt-get install tmux
  • Confirm that it installed by checking the version:
    tmux -V

Quick Note:

Use tmux with zsh to make life easier for newbies. Type tmux and then use tabs to find option.

tmux attach-session -t intro-c

Keyboard shortcut interpretation for newwbies: dont get lost in the usage of this shortcut syntax. Follow the Example:

^b d 
# or 
ctrl+b d 
means =>  Press Ctrl hold, press b. Then release both and press d

Syntax used here: * ALT * ^ CTRL * + hold (press and hold)

Basic tmux usage:

tmux new -s [session name]
# Start new named session:

ctrl+b d
# Detach from session:

tmux ls
# List sessions:

tmux a -t [name of session] 
# Attach to named session:

tmux attach-session -t [name of session]
# OR

tmux kill-session -t [name of session]
# Kill named session:

ctrl+b "
# Split panes horizontally: use Shift keys to get upper " or %

ctrl+b %
# Split panes vertically:

ctrl+b x
# Kill current pane:

ctrl+b [arrow key]
# Move to another pane:

tmux kill-server
# Kill tmux server, along with all sessions:

Keyboard shortcuts within the tmux shell/ window:

^b then c 
# To create a new window

^b then n 
# To switch to the next window

^b then , 
# Then [type something] then ⌤ to rename the current window

^b then % 
# To split the current window into panes vertically

^b then " 
# To split the current window into panes horizontally

^b then ↑ 
# (arrows) to move to the above pane (works for all four arrows)

^b then q 
# To show pane numbers, then (optionally) the number to switch to that pane

^b then ⎇(Alt)+↑(arrow keys) 
# To resize the current pane up (works for all four arrows)

^b then x 
# To kill the current pane (or window if it only has one pane)

^b then [ 
# To enter copy mode, then four arrow keys to move, even past the visible point, which is great for scrolling--I don't use it much for copying/pasting.
