想要通过在任务完成时在最后一行末尾打印[确定]来做一个奇特的效果.

明白啦:

echo "$0: Starting backup process in '$backupdir'... " 
sleep 3
echo '[OK]'

我尝试不同的东西在第一回波的终点,在第二喜欢的开始\r,\c,\,GOOGLE了它...没有好.

我希望它输出这个:

./backup.sh: Starting backup process in '/backup'...

...... 3秒后,添加[OK]:

./backup.sh: Starting backup process in '/backup'... [OK]

谢谢,
