设置或更改光标的垂直位置 [英] Set or change vertical position of the cursor

问题描述

据我所知，这是可以使用退格序列将光标移动到左侧的中的回声的。但是，是否有可能改变光标的垂直位置，使用的回声的？

As far as I know, it is possible to move the cursor to the left using the backspace sequence in an echo. But is there any possibility to change the vertical position of the cursor, using an echo?

推荐答案

本节介绍ANSI转义序列：

This section describes the ANSI escape sequences:

• http://www.tldp.org/HOWTO/Bash-Prompt-HOWTO/x361.html

例如：

echo -en "\033[s\033[7B\033[1;34m 7 lines down violet \033[u\033[0m"
echo -en "\033[s\033[7A\033[1;32m 7 lines up green \033[u\033[0m"

和本节介绍tput的实用工具：

从<一个采取一个示例脚本href=\"http://www.cyberciti.biz/tips/spice-up-your-unix-linux-shell-scripts.html\">http://www.cyberciti.biz/tips/spice-up-your-unix-linux-shell-scripts.html:

#!/bin/bash

tput clear      # clear the screen

tput cup 3 15   # Move cursor to screen location X,Y (top left is 0,0)

tput setaf 3    # Set a foreground colour using ANSI escape
echo "XYX Corp LTD."
tput sgr0

tput cup 5 17
tput rev        # Set reverse video mode
echo "M A I N - M E N U"
tput sgr0

tput cup 7 15; echo "1. User Management"
tput cup 8 15; echo "2. Service Management"
tput cup 9 15; echo "3. Process Management"
tput cup 10 15; echo "4. Backup"

tput bold       # Set bold mode 
tput cup 12 15
read -p "Enter your choice [1-4] " choice

tput clear
tput sgr0
tput rc
