test.sh：
#!/bin/bash

Put an exit and see
放一个出口看看
#!/bin/bash
echo "helloworld"
exit

I'd look for funny business in error/signal handlers and or the PROMPT_COMMAND
我会在错误/信号处理程序和PROMPT_COMMAND中寻找有趣的业务
So,
所以，
echo $PS1
echo $PROMPT_COMMAND
trap
would be in order.
会有秩序的。
Another approach is to make bash run restricted (which disables a whole slew of options)
另一种方法是限制bash运行（禁用一大堆选项）
#!/bin/bash -r
While the latter may resolve the strange behaviour, it wouldn't explain waht happened
虽然后者可以解决这种奇怪的行为，但它无法解释发生的事情

I guess edited from Windows/reused a Windows-file with an \r inside, which you moved around with inserting exit?
我想从Windows编辑/重用一个带有\ r里面的Windows文件，你在插入退出时移动了吗？
