[tmux](http://tmux.github.io)
|
|
is a terminal multiplexer: it enables a number of terminals
|
|
to be created, accessed, and controlled from a single screen. tmux
|
|
may be detached from a screen and continue running in the background
|
|
then later reattached.
|
|
|
|
|
|
```
|
|
|
|
tmux [command] # Run a command
|
|
# 'tmux' with no commands will create a new session
|
|
|
|
new # Create a new session
|
|
-s "Session" # Create named session
|
|
-n "Window" # Create named Window
|
|
-c "/dir" # Start in target directory
|
|
|
|
attach # Attach last/available session
|
|
-t "#" # Attach target session
|
|
-d # Detach the session from other instances
|
|
|
|
ls # List open sessions
|
|

|

|

|
|

### Key Bindings
|
|
|
|
The method of controlling an attached tmux session is via key
|
|
combinations called 'Prefix' keys.
|
|
|
|
```
|
|
----------------------------------------------------------------------
|
|
(C-b) = Ctrl + b # 'Prefix' combination required to use keybinds
|
|
|
|
(M-1) = Meta + 1 -or- Alt + 1
|
|
----------------------------------------------------------------------
|
|
|
|
? # List all key bindings
|
|
: # Enter the tmux command prompt
|
|
r # Force redraw of the attached client
|
|
c # Create a new window
|
|
|
|
! # Break the current pane out of the window.
|
|
% # Split the current pane into two, left and right
|
|
" # Split the current pane into two, top and bottom
|
|
|
|
n # Change to the next window
|
|
p # Change to the previous window
|
|
{ # Swap the current pane with the previous pane
|
|
} # Swap the current pane with the next pane
|
|
[ # Enter Copy Mode to copy text or view history.
|
|
|
|
s # Select a new session for the attached client
|
|
interactively
|
|
w # Choose the current window interactively
|
|
0 to 9 # Select windows 0 to 9
|
|
|
|
d # Detach the current client
|
|
D # Choose a client to detach
|
|
|
|
& # Kill the current window
|
|
x # Kill the current pane
|
|
|
|
Up, Down # Change to the pane above, below, left, or right
|
|
Left, Right
|
|
|
|
M-1 to M-5 # Arrange panes:
|
|
# 1) even-horizontal
|
|
# 2) even-vertical
|
|
# 3) main-horizontal
|
|
# 4) main-vertical
|
|
# 5) tiled
|
|
|
|
C-Up, C-Down # Resize the current pane in steps of one cell
|
|
C-Left, C-Right
|
|
|
|

|
|

### Configuring ~/.tmux.conf
|
|
|
|
tmux.conf can be used to set options automatically on start up, much
|
|
like how .vimrc or init.el are used.
|
|
|
|
```
|
|
# Example tmux.conf
|
|
# 2015.12
|
|
|
|
|
