# split panes using | and -
bind | split-window -h
bind - split-window -v
unbind '"'
unbind %

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

# Enable mouse mode (tmux 2.1 and above)
set -g mouse on

eval needs to be defined after the plugins, but before source $ZSH/oh-my-zsh.sh

eval "$(dircolors -p | \
    sed 's/ 4[0-9];/ 01;/; s/;4[0-9];/;01;/g; s/;4[0-9] /;01 /' | \
    dircolors /dev/stdin)"

Get rid of colorized shell

Comment the following lines

# set a fancy prompt (non-color, unless we know we "want" color)
case "$TERM" in
    xterm-color|*-256color) color_prompt=yes;;
esac

# enable color support of ls and also add handy aliases
if [ -x /usr/bin/dircolors ]; then
    test -r ~/.dircolors && eval "$(dircolors -b ~/.dircolors)" || eval "$(dir$
    alias ls='ls --color=auto'
    #alias dir='dir --color=auto'
    #alias vdir='vdir --color=auto'

    alias grep='grep --color=auto'
    alias fgrep='fgrep --color=auto'
    alias egrep='egrep --color=auto'
