我对执行文件操作的脚本有疑问

我一直在开发一个脚本，该脚本可以立即检测在下载目录中创建的文件，然后根据文件扩展名对它们进行排序。然而，这样做的问题是，当从互联网下载文件时，它会移动文件，同时下载会损坏文件。

有没有办法可以停止脚本的操作直到完成？例如，我有一个想法，我注意到，当从互联网下载文件时，我通常会看到一个带有 .part 文件扩展名的文件，我可以添加一些内容，当它检测到此文件扩展名时，会循环直到它消失，然后继续执行其余部分剧本？

如果我不乐意接受任何建议，如果您有疑问，请直接询问。 -谢谢

我相信我已经解决了这个问题，幸运的是，我能够遇到一个比我更有才华的 Linux 用户，他也是该脚本的共同作者，不会透露姓名，因为这对我来说很粗鲁，但他出现了在“| while read FILENAME; do”末尾添加此行“[ -s“$TARGET/$FILENAME”] || continue”不知道它会做什么，因为我是新手，但现在脚本将等待直到文件下载完成后再移动它们。
