Ubuntu – How to adjust the terminal shell window width

Terminator does allow you setting up a default size. :)

Just open the file ~/.config/terminator/config with your favorite editor. You should have a section titled [layouts]. You only need to add a line within the sub-section named [[[window0]]] belonging to the [[default]] section. My configuration file, for instance, looks like this:

[global_config]
  enabled_plugins = CustomCommandsMenu, InactivityWatch, ActivityWatch, TerminalShot, LaunchpadCodeURLHandler, LaunchpadBugURLHandler
[keybindings]
[profiles]
  [[default]]
    scrollbar_position = hidden
    visible_bell = True
    scrollback_lines = 1000000
    foreground_color = "#ffffff"
    copy_on_selection = True
    background_color = "#300a24"
[layouts]
  [[default]]
    [[[child1]]]
      type = Terminal
      parent = window0
      profile = default
    [[[window0]]]
      type = Window
      parent = ""
      profile = None
      size = 900, 600
[plugins]

The relevant part is only the line starting with "size", of course.

Use following on the top of your expect script:

#trap sigwinch and pass it to the child we spawned
trap {
 set rows [stty rows]
 set cols [stty columns]
 stty rows $rows columns $cols < $spawn_out(slave,name)
} WINCH
