Tmux is a terminal multiplexer. Tested with tmux 1.5+.

This config has support for tmux-mem-cpu-load.

Prefix mapped to Ctrl-A for screen users.



git clone ~/.tmux

Copy tmux config to home:

ln -s ~/.tmux/.tmux.conf ~/.tmux.conf

Go to config dir:

cd ~/.tmux



Works on Linux and OS X.

Prep ourself to download submodule:

git submodule init

Download submodule:

git submodule update

Change dir to tmux-mem-cpu-load:

cd ~/.tmux/vendor/tmux-mem-cpu-load

General make file:

cmake .

Compile our binary:


Install our binary to /usr/local/bin/tmux-mem-cpu-load:

sudo make install

Go home:

cd ~

Launch tmux:


And press Control + a then d to go back to the terminal.

Update config:

tmux source-file ~/.tmux.conf


(Cross platform, tested with python 2.7+)

Update March 19, 2014. Works with psutil 2.0 now.

Install psutil:

sudo pip install psutil

copy ~/.tmux/vendor/basic-cpu-and-memory.tmux to bin:

sudo cp ~/.tmux/vendor/basic-cpu-and-memory.tmux /usr/local/bin/tmux-mem-cpu-load

make executable:

sudo chmod +x /usr/local/bin/tmux-mem-cpu-load

Powerline (Advanced)

You can add suport for powerline by adding these to your ~/.tmux.conf. Be sure to grab and install powerline-fonts for your system.

See Powerline on for more info.

Start tmux

To start a session:


To reattach a previous session:

tmux attach

To reload config file

<Control + b>: (which could Ctrl-B or Ctrl-A if you overidden it) then source-file ~/.tmux.conf


Our prefix/leader key is Control + a now (just like the screen multiplexer). This sequence must be typed before any tmux shortcut.

  • Control + a before any command
  • Control + a then ? to bring up list of keyboard shortcuts
  • Control + a then " to split window
  • Control + a then <Space> to change pane arrangement
  • Control + a then o to rotate panes
  • Control + a then h, j, k, l to move left, down, up, right. Respectively. (vim hjkl)
  • Control + a then ; to go to last panel

Beyond your first window:

  • Control + a then c to create a new window
  • Control + a then n to next window
  • Control + a then p to previous window
  • Control + a then [0-9] move to window number
  • Control + a then & to kill window


  • Control + a then m to switch to main-horizontal layout with the main window at 60% height.
