# screen -D -R can be emulated with:
# if ! test "$TERM" == screen; then tmux attach || tmux; exit; fi
# (new tmux shells read .bash_profile not .bashrc, so the
# 'if' is necessary to avoid recursion; you might also want
# to check that $TERM is not "dumb" to avoid scp trouble)

# Turn off the status line for more real-estate, like screen:
set-option -g status off

# You can temporarily turn status on/off from the command line, e.g.:
# tmux set-option -g status on
# tmux set-option -g status off
# but it's usually easier to do the choose-window command
# (C-a " in screen's keybindings).  Anyway here are some
# colours for it if you do turn it on:
set-option -g status-style fg=brightwhite,bg=blue
set-option -g window-status-style bg=blue
set-option -g window-status-current-style bg=red
set-option -g window-status-bell-style bg=black
set-option -g window-status-activity-style bg=magenta
set-option -g message-style bg=blue,fg=brightyellow
set-option -g message-command-style bg=blue,fg=brightwhite
# and these colours are for the choose-window command:
set-option -g mode-style fg=brightwhite,bg=blue
# If you have an old version of tmux (1.8 or below) then
# comment out the above 'style' lines and uncomment these:
# set-option -g status-fg brightwhite
# set-option -g status-bg blue
# set-option -g window-status-bg blue
# set-option -g window-status-current-bg red
# set-option -g window-status-bell-bg black
# set-option -g window-status-activity-bg magenta
# set-option -g mode-fg brightwhite
# set-option -g mode-bg blue
# set-option -g message-bg blue
# set-option -g message-command-bg blue
# set-option -g message-fg brightyellow
# set-option -g message-command-fg brightwhite
# (can also set window-status-.*-fg exceptions if desired)

# and we also want more time to read messages etc:
set-option -g escape-time 2000
set-option -g display-time 3000
set-option -g display-panes-time 2000

# Can do it from the command line:
# tmux display-message "text here"
# c.f. screen -X wall "text here"

# Option removed in tmux 1.9 (Debian 8):
# set-option -g default-path "."

# changes to get it to work on the tmux in Debian
