什么是 tput？tput 命令将通过 terminfo 数据库对您的终端会话进行初始化和操作。通过使用 tput，您可以更改几项终端功能，如移动或更改光标、更改文本属性，以及清除终端屏幕的特定区域。
什么是 terminfo 数据库？
UNIX 系统上的 terminfo 数据库用于定义终端和打印机的属性及功能，包括各设备（例如，终端和打印机）的行数和列数以及要发送至该设备的文本的属性。UNIX 中的几个常用程序都依赖 terminfo 数据库提供这些属性以及许多其他内容，其中包括 vi 和 emacs 编辑器以及 curses 和 man 程序。
命令行使用说明：
1.文本属性
tput Color Capabilities:tput setab [0-7] – Set a background color using ANSI escape
tput setb [0-7] – Set a background color
tput setaf [0-7] – Set a foreground color using ANSI escape
tput setf [0-7] – Set a foreground colorColor Code for tput:
0 – Black
1 – Red
2 – Green
3 – Yellow
4 – Blue
5 – Magenta
6 – Cyan
7 – Whitetput Text Mode Capabilities:
tput bold – Set bold mode
tput dim – turn on half-bright mode
tput smul – begin underline mode
tput rmul – exit underline mode
tput rev – Turn on reverse mode
tput smso – Enter standout mode (bold on rxvt)
tput rmso – Exit standout mode
tput sgr0 – Turn off all attributes
例子：使输出的字符串有颜色，底色，加粗
#!/bin/bash
printf $(tput setaf 2; tput bold)'color show\n\n'$(tput sgr0)
for((i=0; i<=7; i++)); do
echo $(tput setaf $i)"show me the money"$(tput sgr0)
done
printf '\n'$(tput setaf 2; tput setab 0; tput bold)'background color show'$(tput sgr0)'\n\n'
for((i=0,j=7; i<=7; i++,j--)); do
echo $(tput setaf $i; tput setab $j; tput bold)"show me the money"$(tput sgr0)
done
exit 0输出格式控制函数：
#!/bin/bash# $1 str print string
# $2 color 0-7 设置颜色
# $3 bgcolor 0-7 设置背景颜色
# $4 bold 0-1 设置粗体
# $5 underline 0-1 设置下划线function format_output(){
str=$1
color=$2
bgcolor=$3
bold=$4
underline=$5

format_output "Yesterday Once More" 2 5 1 1
exit 0
2.光标属性
#!/bin/bash
tput clear # 清屏
tput sc # 保存当前光标位置
tput cup 10 13 # 将光标移动到 row col
tput civis # 光标不可见
tput cnorm # 光标可见
tput rc # 显示输出
exit 0例子：
#!/bin/bash
# clear the screen
tput clear
# Move cursor to screen location X,Y (top left is 0,0)
tput cup 3 15
# Set a foreground colour using ANSI escape
tput setaf 3
echo "XYX Corp LTD."
tput sgr0
tput cup 5 17
# Set reverse video mode
tput rev
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"
# Set bold mode
tput bold
tput cup 12 15
