什么设置控制我的 .dialogrc 文件中的此功能？

Question

我正在编写一个 bash 脚本供个人使用，它使用dialog。我的脚本是：

#!/bin/bash                                                              
DIALOG=${DIALOG=dialog}

$DIALOG --title "Title" --clear \
    --msgbox "hello world" 18 64
clear

运行脚本会生成一个如下所示的菜单：

我想改变OK突出显示选择的方式。理想情况下，我希望整个OK“按钮”轮廓或文本在选择时改变颜色，但我会满足于突出显示为O不同的颜色。设置由我的.dialogrc文件控制，如下所示。

#
# Run-time configuration file for dialog
#
# Automatically generated by "dialog --create-rc <file>"
#
#
# Types of values:
#
# Number     -  <number>
# String     -  "string"
# Boolean    -  <ON|OFF>
# Attribute  -  (foreground,background,highlight?)

# Set aspect-ration.
aspect = 0

# Set separator (for multiple widgets output).
separate_widget = ""

# Set tab-length (for textbox tab-conversion).
tab_len = 0

# Make tab-traversal for checklist, etc., include the list.
visit_items = OFF

# Shadow dialog boxes? This also turns on color.
use_shadow = OFF

# Turn color support ON or OFF
use_colors = OFF

# Screen color
screen_color = (CYAN,BLUE,ON)

# Shadow color
shadow_color = (BLACK,BLACK,ON)

# Dialog box color
dialog_color = (BLACK,WHITE,OFF)

# Dialog box title color
title_color = (BLUE,WHITE,ON)

# Dialog box border color
border_color = (WHITE,WHITE,ON)

# Active button color
button_active_color = (WHITE,BLUE,ON)

# Inactive button color
button_inactive_color = dialog_color

# Active button key color
button_key_active_color = button_active_color

# Inactive button key color
button_key_inactive_color = (RED,WHITE,OFF)

# Active button label color
button_label_active_color = (YELLOW,BLUE,ON)

# Inactive button label color
button_label_inactive_color = (BLACK,WHITE,ON)

# Input box color
inputbox_color = dialog_color

# Input box border color
inputbox_border_color = dialog_color

# Search box color
searchbox_color = dialog_color

# Search box title color
searchbox_title_color = title_color

# Search box border color
searchbox_border_color = border_color

# File position indicator color
position_indicator_color = title_color

# Menu box color
menubox_color = dialog_color

# Menu box border color
menubox_border_color = border_color

# Item color
item_color = dialog_color

# Selected item color
item_selected_color = button_active_color

# Tag color
tag_color = title_color

# Selected tag color
tag_selected_color =  button_label_active_color

# Tag key color
tag_key_color = button_key_inactive_color

# Selected tag key color
tag_key_selected_color = (RED,BLUE,ON)

# Check box color
check_color = dialog_color

# Selected check box color
check_selected_color = button_active_color

# Up arrow color
uarrow_color = (GREEN,WHITE,ON)

# Down arrow color
darrow_color = uarrow_color

# Item help-text color
itemhelp_color = (WHITE,BLACK,OFF)

# Active form text color
form_active_text_color = button_active_color

# Form text color
form_text_color = (WHITE,CYAN,ON)

# Readonly form item color
form_item_readonly_color = (CYAN,WHITE,ON)

# Dialog box gauge color
gauge_color = title_color

# Dialog box border2 color
border2_color = dialog_color

# Input box border2 color
inputbox_border2_color = dialog_color

# Search box border2 color
searchbox_border2_color = dialog_color

# Menu box border2 color
menubox_border2_color = dialog_color

是否可以编辑此文件以获得我想要的结果？我试过更改一些设置，但我尝试过的所有设置要么没有更改，要么导致错误。

我正在使用 crouton 在 chromebook 上运行 Ubuntu 14.04。

屏幕截图中突出显示的“O”是终端的光标。你无法控制它的外观，它是根据每个用户的终端设置呈现的。

例如，以下是它在 OS X 终端中使用默认光标样式（“块光标”）的显示方式： 这是将光标样式更改为“垂直条”： 这是通过tput civis在对话框命令之前运行使光标不可见（并tput cnorm在对话框运行后使其再次可见）：
