请注意，该脚本可以正常工作（执行所需的操作），但由于我正在努力将此脚本共享给其他人，因此该错误很麻烦。我试图避免错误。

首先，这不是现在的bash脚本 - 它是一个bourne shell脚本。如果你想使用bash改变第一行（“shebang”）来使用/bin/bash。您在评论中显示系统中/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bash脚本，如：/bin/bash -x script.sh;或者将shebang改为#!/bin/bash -x（暂时）。

顺便说一句，您正在测试目录并在它们不存在时创建它们。如果您要在if子句中执行所有操作，则可以使用普通mkdir -p，因此如果路径已存在则不会引发错误。请注意，它可能并非在所有* nix系统中都可用，但它位于GNU / Linux中。

查看sh //*sh;，看看有什么匹配的脚本？此行基本匹配并运行以/路径下的sh结尾的任何脚本。

在EOF错误之后，bash脚本没有正确退出（期待）;
