"echo"命令还有其他选择吗？

Question

除了"echo"之外，是否有其他命令可用于在bash中向终端显示文本？

最好是可以输出到终端中的任何点的。

Answer 1

也许 tput 就是你要找的。例如，您可以创建一个小菜单，如下所示：

#!/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. Not sure this works on OSX
tput setaf 3
# Set reverse video mode
tput rev
echo "S U S H I  M E N U  I T E M S"
tput sgr0
tput cup 5 17
echo "Please select an option"
tput sgr0
tput cup 7 15
echo "1. Sushi Sashimi Combo"
tput cup 8 15
echo "2. Omakase"
tput cup 9 15
echo "3. Chirashi"
tput cup 10 15
echo "4. Eel and Avacado Roll"

# Set bold mode 
tput bold
tput cup 12 15
read -p "Enter your choice [1-4] " choice
tput clear
tput sgr0
tput rc
echo "You chose $choice"
