tmux/Option/status-right

• status-right

  • A tmux session option holding the format string drawn at the right end of the tmux/Status Line. The default shows the tmux/Pane/Title in double quotes, then the time and the date:

    • #{?window_bigger,[#{window_offset_x}#,#{window_offset_y}] ,}"#{=21:pane_title}" %H:%M %d-%b-%y

  • The #{=21:pane_title} cell caps the pane title at twenty-one characters inside the format string, independent of tmux/Option/status-right-length. Shortening that number is what narrows the right end; lowering the length cap on its own takes the date and time away instead.
  • Once a pane title is long enough to reach the cell cap, the whole expansion is 39 columns wide — near enough the default status-right-length of 40 that the right end runs at full width all the time.

  • Usage

    • Show it, and measure what it currently wants:
      • sh

        tmux show-options -gv status-right
        tmux display-message -p '#{w:#{T:status-right}}'

    • Return eleven columns to the window list by shortening the title cell — 39 columns become 28:
      • sh

        set -g status-right '"#{=10:pane_title}" %H:%M %d-%b-%y'
        set -g status-right-length 30
