tmux

Last substantive revision: 2016-10-27

For now, this page is mostly a placeholder.

I use tmux to spawn multiple shell sessions while I work. Even though I mainly use Terminator (which supports tabs and window splitting) as my terminal emulator, I find that tmux gives me enough flexibility (through its windows and panes) that I don’t use the corresponding features in Terminator. On my servers, I keep a tmux session running so that I can attach to it to continue working where I stopped.

# Use 256 colors
set -g default-terminal "screen-256color"

set-option -g default-shell /bin/zsh

# Make <C-[> work properly in Vim
set -s escape-time 0

unbind C-b
#set -g prefix C-q
#bind C-q send-prefix
set -g prefix C-Space
# this one is to pass in a literal one right?
bind C-Space send-prefix

# tmux changed its mouse options in going from 2.0 to 2.1, so we make it work
# in all versions.
# for tmux >= 2.1
set -g mouse on
# for tmux < 2.1
#set -g mode-mouse on
#set -g mouse-resize-pane on
#set -g mouse-select-pane on
#set -g mouse-select-window on

set -g history-limit 10000

# Use Vi keys; see http://blog.sanctum.geek.nz/vi-mode-in-tmux/ and
# https://robots.thoughtbot.com/love-hate-tmux
set-window-option -g mode-keys vi
bind-key -t vi-copy 'v' begin-selection
bind-key -t vi-copy 'y' copy-selection
bind -t vi-copy Escape cancel
#bind h select-pane -L
#bind j select-pane -D
#bind k select-pane -U
#bind l select-pane -R

# for newer tmux? from http://unix.stackexchange.com/questions/146825/tmux-new-pane-has-home-directory-as-default-instead-of-previous-directory
# This preserves the directory when splitting panes.
bind '%' split-window -h -c '#{pane_current_path}'  # Split panes horizontal
bind '"' split-window -v -c '#{pane_current_path}'  # Split panes vertically

# Also note that tmux doesn't process ~/.bashrc so do
# `echo 'source ~/.bashrc' >> ~/.bash_profile`; see
# http://stackoverflow.com/a/16225913 for more
