1.4. TMUX

Tmux is Terminal MUlti-pleXer. It needs some custom settings to make it:

These are my “easier to use commands”:




Start a terminal multiplexer session

tmux kill-server

Kill the server

tmux list-sessions

List sessions


Create another pane horizontally and put the cursor in that pane


Create another pane vertically and put the cursor in that pane

Alt-{up, down, left, right} cursor keys

Move from one pane to another {up, down, left, right}

Mouse click pane

Move from one pane to another


Kill a pane


Rename a window


Create a new window


Kill a window


Move from window to window {up, down}

Hold shift and highlight


Hold shift and middle mouse


The configuration file implements this easier to use and look better requirements:

1.4.1. Edit config files


override system /etc/tmux.conf with ~/.tmux.conf

1.4.2. Change control-b to control-a

# remap prefix from ‘C-b’ to ‘C-a’ unbind C-b set-option -g prefix C-a bind-key C-a send-prefix

To reload your ~/.tmux.conf without killing your session, you can simply do:

C-b :source-file /absolute/path/to/your/.tmux.conf

# split panes using v and h bind v split-window -h bind h split-window -v unbind ‘”’ unbind %

C-a :source-file /home/andrew/.tmux.conf

# reload config file (change file location to your the tmux.conf you want to use) bind r source-file ~/.tmux.conf

# switch panes using Alt-arrow without prefix bind -n M-Left select-pane -L bind -n M-Right select-pane -R bind -n M-Up select-pane -U bind -n M-Down select-pane -D

# horizontal and vertical splitting via meta bind -n M-h split-window -h bind -n M-v split-window -v

# Enable mouse control (clickable windows, panes, resizable panes) set -g mouse on

# don’t rename windows automatically set-option -g allow-rename off

# rename window bind -n M-r command-prompt -I “#W” “rename-window ‘%%’”

#kill pane bind -n M-x kill-pane

#new window bind -n M-w new-window

#kill window bind -n M-k kill-window

#previous window bind -n M-PAGEUP previous-window

#next window bind -n M-PAGEDOWN next-window

# if something goes wrong with colours - reset them: tmux kill-server

# list sessions tmux list-sessions

1.4.3. Tmux Themepack

git clone https://github.com/jimeh/tmux-themepack.git ~/.tmux-themepack

1.4.4. Powerline fonts

# clone
git clone https://github.com/powerline/fonts.git --depth=1
# install
cd fonts
# clean-up a bit
cd ..
rm -rf fonts

1.4.5. Powerline fonts dont line up


fontforge -lang ff -c ‘Open($1); Generate($2)’ powerline-symbols.sfd powerline-symbols.ttf

After I removed my PowerlineSymbols.otf from my /usr/share/fonts, I moved the PowerlineSymbols.ttf in /usr/share/fonts and ran sudo fc-cache -vf. That worked for me. For some reason, when the PowerlineSymbols.ttf didn’t work when it was in my local .fonts directory

On Ubuntu 18.04 I must do: tmux > Edit > Preferences > Text > Source Code Pro for Powerline Fonts

1.4.6. Change font color to 100 on line 32 of green,tmuxtheme

set -g window-status-current-format “#[fg=colour233,bg=black]#[fg=colour100,nobold] #I:#W#F #[fg=colour233,bg=black,nobold]”

1.4.7. Add this to tmux.conf

source-file “${HOME}/.tmux-themepack/powerline/double/green.tmuxtheme”

1.4.8. TMUX Resurrect

$ git clone https://github.com/tmux-plugins/tmux-resurrect ~/clone/path

Add this to tmux.conf:

run-shell ~/clone/path/resurrect.tmux

Reload TMUX environment with:

$ tmux source-file ~/.tmux.conf
