If you're new to tmux, I recommend you read tmux 2: Productive Mouse-Free Development by @bphogan.


  • **I'm running tmux
    and things don't work properly. What should I do?**

Please open an issue describing what doesn't work with upcoming tmux. I'll do my best to address it.

  • Status line is broken and/or gets duplicated at the bottom of the screen. What gives?

This particularly happens on Linux when the distribution provides a version of glib that received Unicode 9.0 upgrades (glib

\>= 2.50.1

) while providing a version of glibc that didn't (glibc

\< 2.26

). You may also configure


to use an


locale. Typically VTE based terminal emulators rely on glib's


function while tmux relies on glibc's


function. When these two functions disagree, display gets messed up.

This can also happen on macOS when using iTerm2 and "Use Unicode version 9 character widths" is enabled in

Preferences... \> Profiles \> Text

For that reason, the default


file stopped using Unicode characters for which width changed in between Unicode 8.0 and 9.0 standards, as well as Emojis.

  • I installed Powerline and/or (patched) fonts but can't see Powerline symbols.

First, you don't need to install Powerline. You only need fonts patched with Powerline symbols or the standalone


font. Then make sure your


copy uses the right code points for



  • I'm using Bash On Windows (WSL), colors and Powerline look are broken.

There is currently a bug in the new console powering Bash On Windows preventing text attributes (bold, underscore, ...) to combine properly with colors. The workaround is to search your


copy and replace attributes with



Also, until Window's console replaces its GDI based render with a DirectWrite one, Powerline symbols will be broken.

The alternative is to use the Mintty terminal for WSL.


The "maximize any pane to a new window with

<prefix> +</prefix>

" feature is different from builtin

resize-pane -Z

as it allows you to further split a maximized pane. It's also more flexible by allowing you to maximize a pane to a new window, then change window, then go back and the pane is still in maximized state in its own window. You can then minimize a pane by using

<prefix> +</prefix>

either from the source window or the maximized window.

Maximize pane

Mouse mode allows you to set the active window, set the active pane, resize panes and automatically switches to copy-mode to select text.

tmux may be controlled from an attached client by using a key combination of a prefix key, followed by a command key. This configuration uses


as a secondary prefix while keeping


as the default prefix. In the following list of key bindings: -

<prefix> c</prefix>

means you have to hit Ctrl + a or Ctrl + b followed by c -

<prefix> C-c</prefix>

means you have to hit Ctrl + a or Ctrl + b followed by Ctrl + c

Enabling the Powerline look

Powerline originated as a status-line plugin for Vim. Its popular eye-catching look is based on the use of special symbols: Powerline Symbols

To make use of these symbols, there are several options:

Please see the Powerline manual for further details.

Then edit the


file (

<prefix> e</prefix>

) and adjust the following variables:

tmux\_conf\_theme\_left\_separator\_main='\uE0B0' tmux\_conf\_theme\_left\_separator\_sub='\uE0B1' tmux\_conf\_theme\_right\_separator\_main='\uE0B2' tmux\_conf\_theme\_right\_separator\_sub='\uE0B3'

Configuring the status line

Contrary to the first iterations of this configuration, by now you have total control on the content and order of





Edit the


file (

<prefix> e</prefix>

) and adjust the




variables to your own preferences.

This configuration supports the following builtin variables:

  • #{battery\_bar}
    : horizontal battery charge bar
  • #{battery\_percentage}
    : battery percentage
  • #{battery\_status}
    : is battery charging or discharging?
  • #{battery\_vbar}
    : vertical battery charge bar
  • #{circled\_session\_name}
    : circled session number, up to 20
  • #{hostname}
    : SSH/Mosh aware hostname information
  • #{hostname\_ssh}
    : SSH/Mosh aware hostname information, blank when not connected to a remote server through SSH/Mosh
  • #{loadavg}
    : load average
  • #{pairing}
    : is session attached to more than one client?
  • #{prefix}
    : is prefix being depressed?
  • #{root}
    : is current user root?
  • #{synchronized}
    : are the panes synchronized?
  • #{uptime\_y}
    : uptime years
  • #{uptime\_d}
    : uptime days, modulo 365 when
    is used
  • #{uptime\_h}
    : uptime hours
  • #{uptime\_m}
    : uptime minutes
  • #{uptime\_s}
    : uptime seconds
  • #{username}
    : SSH/Mosh aware username information
  • #{username\_ssh}
    : SSH aware username information, blank when not connected to a remote server through SSH/Mosh

Beside custom variables mentioned above, the




variables support usual tmux syntax, e.g. using


to call an external command that inserts weather information provided by

tmux_conf_theme_status_right='#{prefix}#{pairing}#{synchronized} #(curl , %R , %d %b | #{username}#{root} | #{hostname} ' ```

Using the configuration under Cygwin within Mintty

**I don't recommend running this configuration with Cygwin anymore. Forking under Cygwin is extremely slow and this configuration issues a lot of


commands under the hood. As such, you will experience high CPU usage. As an alternative consider using Mintty terminal for WSL.**


It is possible to use this configuration under Cygwin within Mintty, however support for Unicode symbols and emojis lacks behind Mac and Linux.

Particularly, Mintty's text rendering is implemented with GDI which has limitations:

  • color emojis are only available through DirectWrite starting with Windows 8.1
  • display of double width symbols, like the battery discharging symbol indicator (U+1F50B) is buggy

To get Unicode symbols displayed properly, you have to use font linking. Open


then navigate to the registry key at

HKEY\_LOCAL\_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink

and add a new entry for you preferred font to link it with the Segoe UI Symbol font.
