13 - tmux **`>= 2.1`** (soon `>= 2.4`) running inside Linux, Mac, OpenBSD, Cygwin
16 - outside of tmux, `$TERM` must be set to `xterm-256color`
18 To install, run the following from your terminal: (you may want to backup your
19 existing `~/.tmux.conf` first)
23 $ git clone https://github.com/gpakosz/.tmux.git
24 $ ln -s -f .tmux/.tmux.conf
25 $ cp .tmux/.tmux.conf.local .
28 Then proceed to [customize] your `~/.tmux.conf.local` copy.
30 [customize]: #enabling-the-powerline-look
32 If you're a Vim user, setting the `$EDITOR` environment variable to `vim` will
33 enable and further customize the vi-style key bindings (see tmux manual).
35 If you're new to tmux, I recommend you read [tmux 2: Productive Mouse-Free
36 Development][bhtmux2] by [@bphogan].

44 - **I'm running tmux `HEAD` and things don't work properly. What should I do?**
46 Please open an issue describing what doesn't work with upcoming tmux. I'll do
47 my best to address it.
49 - **Status line is broken and/or gets duplicated at the bottom of the screen.
52 This particularly happens on Linux when the distribution provides a version
53 of glib that received Unicode 9.0 upgrades (glib `>= 2.50.1`) while providing
54 a version of glibc that didn't (glibc `< 2.26`). You may also configure
55 `LC_CTYPE` to use an `UTF-8` locale. Typically VTE based terminal emulators
56 rely on glib's `g_unichar_iswide()` function while tmux relies on glibc's
57 `wcwidth()` function. When these two functions disagree, display gets messed
60 This can also happen on macOS when using iTerm2 and "Use Unicode version 9
61 character widths" is enabled in `Preferences... > Profiles > Text`
63 For that reason, the default `~/.tmux.conf.local` file stopped using Unicode
64 characters for which width changed in between Unicode 8.0 and 9.0 standards,
67 - **I installed Powerline and/or (patched) fonts but can't see Powerline
70 First, you don't need to install Powerline. You only need fonts patched with
71 Powerline symbols or the standalone `PowerlineSymbols.otf` font. Then make
72 sure your `~/.tmux.conf.local` copy uses the right code points for
73 `tmux_conf_theme_left_separator_XXX` values.
75 - **I'm using Bash On Windows (WSL), colors and Powerline look are broken.**
77 There is currently a [bug][1681] in the new console powering Bash On Windows
78 preventing text attributes (bold, underscore, ...) to combine properly with
79 colors. The workaround is to search your `~/.tmux.conf.local` copy and
80 replace attributes with `'none'`.
82 Also, until Window's console replaces its GDI based render with a DirectWrite
83 one, Powerline symbols will be broken.
85 The alternative is to use the [Mintty terminal for WSL][wsltty].

93 - `C-a` acts as secondary prefix, while keeping default `C-b` prefix
94 - visual theme inspired by [Powerline][]
95 - [maximize any pane to a new window with `<prefix> +`][maximize-pane]
96 - SSH/Mosh aware username and hostname status line information
97 - mouse mode toggle with `<prefix> m`
98 - automatic usage of [`reattach-to-user-namespace`][reattach-to-user-namespace]
100 - laptop battery status line information
101 - uptime status line information
102 - optional highlight of focused pane (tmux `>= 2.1`)
103 - configurable new windows and panes behavior (optionally retain current path)
104 - SSH/Mosh aware split pane (reconnects to remote server)
105 - copy to OS clipboard (needs [`reattach-to-user-namespace`][reattach-to-user-namespace]
106 on macOS, `xsel` or `xclip` on Linux)
107 - support for 4-digit hexadecimal Unicode characters (requires `perl` or Bash >= 4.1.2)
108 - [Facebook PathPicker][] integration if available
109 - [Urlview][] integration if available

115 [Urlview]: https://packages.debian.org/stable/misc/urlview
117 The "maximize any pane to a new window with `<prefix> +`" feature is different
118 from builtin `resize-pane -Z` as it allows you to further split a maximized
119 pane. It's also more flexible by allowing you to maximize a pane to a new
120 window, then change window, then go back and the pane is still in maximized
121 state in its own window. You can then minimize a pane by using `<prefix> +`
122 either from the source window or the maximized window.
124 ![Maximize pane](https://cloud.githubusercontent.com/assets/553208/9890858/ee3c0ca6-5c02-11e5-890e-05d825a46c92.gif)
126 Mouse mode allows you to set the active window, set the active pane, resize
127 panes and automatically switches to copy-mode to select text.

134 tmux may be controlled from an attached client by using a key combination of a
135 prefix key, followed by a command key. This configuration uses `C-a` as a
136 secondary prefix while keeping `C-b` as the default prefix. In the following
137 list of key bindings:
138 - `<prefix>` means you have to either hit <kbd>Ctrl</kbd> + <kbd>a</kbd> or <kbd>Ctrl</kbd> + <kbd>b</kbd>
139 - `<prefix> c` means you have to hit <kbd>Ctrl</kbd> + <kbd>a</kbd> or <kbd>Ctrl</kbd> + <kbd>b</kbd> followed by <kbd>c</kbd>
140 - `<prefix> C-c` means you have to hit <kbd>Ctrl</kbd> + <kbd>a</kbd> or <kbd>Ctrl</kbd> + <kbd>b</kbd> followed by <kbd>Ctrl</kbd> + <kbd>c</kbd>
142 This configuration uses the following bindings:
144 - `<prefix> e` opens `~/.tmux.conf.local` with the editor defined by the
145 `$EDITOR` environment variable (defaults to `vim` when empty)
146 - `<prefix> r` reloads the configuration
147 - `C-l` clears both the screen and the tmux history
149 - `<prefix> C-c` creates a new session
150 - `<prefix> C-f` lets you switch to another session by name
152 - `<prefix> C-h` and `<prefix> C-l` let you navigate windows (default
153 `<prefix> n` and `<prefix> p` are unbound)
154 - `<prefix> Tab` brings you to the last active window
156 - `<prefix> -` splits the current pane vertically
157 - `<prefix> _` splits the current pane horizontally
158 - `<prefix> h`, `<prefix> j`, `<prefix> k` and `<prefix> l` let you navigate
160 - `<prefix> H`, `<prefix> J`, `<prefix> K`, `<prefix> L` let you resize panes
161 - `<prefix> <` and `<prefix> >` let you swap panes
162 - `<prefix> +` maximizes the current pane to a new window
164 - `<prefix> m` toggles mouse mode on or off
166 - `<prefix> U` launches Urlview (if available)
167 - `<prefix> F` launches Facebook PathPicker (if available)
169 - `<prefix> Enter` enters copy-mode
170 - `<prefix> b` lists the paste-buffers
171 - `<prefix> p` pastes from the top paste-buffer
172 - `<prefix> P` lets you choose the paste-buffer to paste from
174 Additionally, `copy-mode-vi` matches [my own Vim configuration][]
176 [my own Vim configuration]: https://github.com/gpakosz/.vim.git
178 Bindings for `copy-mode-vi`:
180 - `v` begins selection / visual mode
181 - `C-v` toggles between blockwise visual mode and visual mode
182 - `H` jumps to the start of line
183 - `L` jumps to the end of line
184 - `y` copies the selection to the top paste-buffer
185 - `Escape` cancels the current operation
190 While this configuration tries to bring sane default settings, you may want to
191 customize it further to your needs. Instead of altering the `~/.tmux.conf` file
192 and diverging from upstream, the proper way is to edit the `~/.tmux.conf.local`
195 Please refer to the default `~/.tmux.conf.local` file to know more about
196 variables you can adjust to alter different behaviors. Pressing `<prefix> e`
197 will open `~/.tmux.conf.local` with the editor defined by the `$EDITOR`
198 environment variable (defaults to `vim` when empty).
200 ### Enabling the Powerline look
202 Powerline originated as a status-line plugin for Vim. Its popular eye-catching
203 look is based on the use of special symbols: <img width="80" alt="Powerline Symbols" style="vertical-align: middle;" src="https://cloud.githubusercontent.com/assets/553208/10687156/1b76dda6-796b-11e5-83a1-1634337c4571.png" />
205 To make use of these symbols, there are several options:
207 - use a font that already bundles those: this is e.g. the case of the
208 [2.030R-ro/1.050R-it version][source code pro] of the Source Code Pro font
209 - use a [pre-patched font][powerline patched fonts]
210 - use your preferred font along with the [Powerline font][powerline font] (that
211 only contains the Powerline symbols): [this highly depends on your operating
212 system and your terminal emulator][terminal support], for instance here's a
213 screenshot of iTerm2 configured to use `PowerlineSymbols.otf`
214 ![iTerm2 + Powerline font](https://user-images.githubusercontent.com/553208/62243890-8232f500-b3de-11e9-9b8c-51a5d38bdaa8.png)

222 Please see the [Powerline manual] for further details.
224 Then edit the `~/.tmux.conf.local` file (`<prefix> e`) and adjust the following
228 tmux_conf_theme_left_separator_main='\uE0B0'
229 tmux_conf_theme_left_separator_sub='\uE0B1'
230 tmux_conf_theme_right_separator_main='\uE0B2'
231 tmux_conf_theme_right_separator_sub='\uE0B3'
233 ### Configuring the status line
235 Contrary to the first iterations of this configuration, by now you have total
236 control on the content and order of `status-left` and `status-right`.
238 Edit the `~/.tmux.conf.local` file (`<prefix> e`) and adjust the
239 `tmux_conf_theme_status_left` and `tmux_conf_theme_status_right` variables to
240 your own preferences.
242 This configuration supports the following builtin variables:
244 - `#{battery_bar}`: horizontal battery charge bar
245 - `#{battery_percentage}`: battery percentage
246 - `#{battery_status}`: is battery charging or discharging?
247 - `#{battery_vbar}`: vertical battery charge bar
248 - `#{circled_session_name}`: circled session number, up to 20
249 - `#{hostname}`: SSH/Mosh aware hostname information
250 - `#{hostname_ssh}`: SSH/Mosh aware hostname information, blank when not
251 connected to a remote server through SSH/Mosh
252 - `#{loadavg}`: load average
253 - `#{pairing}`: is session attached to more than one client?
254 - `#{prefix}`: is prefix being depressed?
255 - `#{root}`: is current user root?
256 - `#{synchronized}`: are the panes synchronized?
257 - `#{uptime_y}`: uptime years
258 - `#{uptime_d}`: uptime days, modulo 365 when `#{uptime_y}` is used
259 - `#{uptime_h}`: uptime hours
260 - `#{uptime_m}`: uptime minutes
261 - `#{uptime_s}`: uptime seconds
262 - `#{username}`: SSH/Mosh aware username information
263 - `#{username_ssh}`: SSH aware username information, blank when not connected
264 to a remote server through SSH/Mosh
266 Beside custom variables mentioned above, the `tmux_conf_theme_status_left` and
267 `tmux_conf_theme_status_right` variables support usual tmux syntax, e.g. using
268 `#()` to call an external command that inserts weather information provided by
271 tmux_conf_theme_status_right='#{prefix}#{pairing}#{synchronized} #(curl wttr.in?format=3) , %R , %d %b | #{username}#{root} | #{hostname} '

278 ### Accessing the macOS clipboard from within tmux sessions
280 [Chris Johnsen created the `reattach-to-user-namespace`
281 utility][reattach-to-user-namespace] that makes `pbcopy` and `pbpaste` work
284 To install `reattach-to-user-namespace`, use either [MacPorts][] or
287 $ port install tmux-pasteboard
291 $ brew install reattach-to-user-namespace
293 Once installed, `reattach-to-usernamespace` will be automatically detected.
295 [MacPorts]: http://www.macports.org/

298 ### Using the configuration under Cygwin within Mintty
300 **I don't recommend running this configuration with Cygwin anymore. Forking
301 under Cygwin is extremely slow and this configuration issues a lot of
302 `run-shell` commands under the hood. As such, you will experience high CPU
303 usage. As an alternative consider using [Mintty terminal for WSL][wsltty].**
305 ![cygwin](https://cloud.githubusercontent.com/assets/553208/19741789/67a3f3d8-9bc2-11e6-9ecc-499fc0228ee6.png)
307 It is possible to use this configuration under Cygwin within Mintty, however
308 support for Unicode symbols and emojis lacks behind Mac and Linux.
310 Particularly, Mintty's text rendering is implemented with GDI which has
313 - color emojis are only available through DirectWrite starting with Windows 8.1
314 - display of double width symbols, like the battery discharging symbol indicator
317 To get Unicode symbols displayed properly, you have to use [font linking].
318 Open `regedit.exe` then navigate to the registry key at
319 `HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\FontLink\SystemLink`
320 and add a new entry for you preferred font to link it with the Segoe UI Symbol
323 ![regedit](https://cloud.githubusercontent.com/assets/553208/19741304/71a2f3ae-9bc0-11e6-96aa-4c09a812c313.png)
