BASH XDOTool 鼠标点击、重复和停止

Question

我正在尝试使用 XDOTool 将一个简单的无限点击脚本与另一段脚本集成以检测键盘输入；在按下某个键但不确定如何匹配它们时结束正在运行的点击脚本。

此脚本无限重复点击屏幕光标点 XXX，XDOTool 确定的 YYY

 #!/bin/bash
 while true [ 1 ]; do
 xdotool mousemove XXX YYY click 1 &
 sleep 1.5
 done

接下来我想使用类似的东西:

#!/bin/bash
if [ -t 0 ]; then stty -echo -icanon -icrnl time 0 min 0; fi
count=0
keypress=''
while [ "x$keypress" = "x" ]; do
let count+=1
echo -ne $count'\r'
keypress="`cat -v`"
done
if [ -t 0 ]; then stty sane; fi
echo "You pressed '$keypress' after $count loop iterations"
echo "Thanks for using this script."
exit 0

我不明白我是如何接受的:

 xdotool mousemove XXX YYY click 1 &
 sleep 1.5

以及将它放在上面脚本中的什么位置，BASH 混淆和 MAN BASH 没有帮助，所以任何可以提供帮助的人都将不胜感激。谢谢

改进(和注释)脚本:

#!/bin/bash

x_pos="0"   # Position of the mouse pointer in X.
y_pos="0"   # Position of the mouse pointer in Y.
delay="1.5" # Delay between clicks.

# Exit if not running from a terminal.
test -t 0 || exit 1

# When killed, run stty sane.
trap 'stty sane; exit' SIGINT SIGKILL SIGTERM

# On exit, kill this script and it's child processes (the loop).
trap 'kill 0' EXIT

# Do not show ^Key when pressing Ctrl+Key.
stty -echo -icanon -icrnl time 0 min 0

# Infinite loop...
while true; do
    xdotool mousemove "$x_pos" "$y_pos" click 1 &
    sleep "$delay"
done & # Note the &: We are running the loop in the background to let read to act.

# Pause until reads a character.
read -n 1

# Exit.
exit 0
