Are there any alternatives to the "echo" command?
提问by Fence_rider
is there a command other than "echo" that can be used to display text to the terminal, in bash?
除了“echo”之外，是否还有其他命令可用于在 bash 中向终端显示文本？
preferably one that can output to any point in the terminal.
最好是可以输出到终端中任何一点的。

Maybe tput is what you're looking for. For example you could create a little menu like so:
也许 tput 就是你要找的。例如，您可以像这样创建一个小菜单：
#!/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"
