这里是新手。尝试编写一个while循环，以检查3个条件，2个用户输入以及ping命令是否失败。如何将所有3个合并为1个大语句？ 想检查用户没有输入Y或y或ping google.com失败
尝试：
# Ask user to confirm ethernet cable connected or quit with Yy or Qq in continous loop.
echo -e "Connect ethernet cable to Pi Slave. Type (Y) when done, (Q) to quit:"
read confirm
# If confirm is Y or y, continue to rest of script
while [[ "$confirm" != "Y" && "$confirm" != "y" && ping -q -c 1 -w 1 google.com ]]
do
if [[ "$confirm" == "Q" || "$confirm" == "q" ]]; then
exit 1
fi
echo -e "Connect ethernet cable to Pi Master. Type (Y) when done, (Q) to quit:"
read confirm
done

function nearestHighestThousand(value) {
if (value < 1) {
return 1000;
} else if (value > 9000) {
return 9000;
} else {
return Math.ceil(value / 1000) * 1000;
}
}
var round = nearestHighestThousand(num);
仅接受简单的测试。像@ECHO OFF

这样的完整命令可以独立存在。
[[ ... ]]要摆脱重复的提示代码，可以将循环重写为：
ping
