简单 bash 递归歧义

Question

我正在编写非常简单的 bash 脚本来更改编码 .html 文件并希望递归处理目录。该功能仅适用于一级目录。你能告诉我哪里错了吗？这是我的代码。

#!/bin/bash

handleFiles () { 
 local REGEXP='.+\.html



测试目录结构如下：

test$ tree 
.
├── test.html
└── Untitled Folder
    └── test1.html

1 directory, 2 files


当我运行脚本时，我得到以下输出：

 ./converter.sh 
test
Converting test/test.html
test/Untitled Folder


作为整个故事我post我的最终解决方案。我希望这对有类似问题的人有用。 

#!/bin/bash

Answer 1

整个方法比必要的要复杂得多。我建议使用 find:

find test -name '*.html' -exec enconv -L bg -x UTF-8 '{}' \;

如果你想手动做，你必须把 $f 放在双引号中（即 "$f"），否则如果目录包含空格它会中断，正如你所注意到的，因为 shell 会将其扩展为两个（或更多，视情况而定）单独的标记。

Answer 2

还引用 </code> 来处理空格（例如 <code>Untitled Folder）：

for f in ""/*
