请注意，该脚本可以工作(执行所需的操作)，但该错误很烦人，因为我正在与他人共享此脚本。我正在努力避免这个错误。

Answer 1

首先，这不是一个bash脚本--它是一个bourne shell脚本。如果您想使用/bin/bash，请将第一行( "shebang")改为使用bash。您在评论中指出，在您的系统中，/bin/sh实际上是dash。dash是bourne shell的最小实现。

您可以通过使用-x运行bash脚本来调试它，如：/bin/bash -x script.sh；或将shebang更改为#!/bin/bash -x (临时)。

顺便说一句，您正在测试目录，并在目录不存在时创建它们。如果这就是您在If子句中要做的全部工作，那么您可以使用一个普通的mkdir -p，这样如果路径已经存在，它就不会引发错误。注意，它可能不是在所有*nix系统中都可用，但它在GNU/Linux中提供。

查看sh //*sh;，看看有没有匹配的脚本？这一行基本上匹配并运行位于/路径下以sh结尾的所有脚本。
