zsh - zmv - 如果有多个连续的大写字母，则不更改大小写

Question

我正在使用 following command

zmv -n -Q '(**/)(*[[:upper:]]*)(/)' '${1}${(L)${2//(#b)([[:upper:]])/-$match[1]}#-}'

改造

% tree
.
├── EmptyFile.txt
├── FirstDirectoryName
│   ├── FourthDirectoryName
│   ├── secondDirectoryName
│   └── thirdDirectoryName
├── FourthDirectoryName
├── secondDirectoryName
└── thirdDirectoryName

到

% tree
.
├── EmptyFile.txt
├── first-directory-name
│   ├── fourth-directory-name
│   ├── second-directory-name
│   └── third-directory-name
├── fourth-directory-name
├── second-directory-name
└── third-directory-name

不过有一个小问题。
如果有多个连续的大写字母，我不想小写。我只想放 -大写字母后面给出的不是开头。

% tree
.
├── DDDDDDD
├── FirstFolderToRename
│   ├── DDDDDDD
│   └── ThisIsDDDDD
├── secondFolderToRename
│   ├── DDDDDDD
│   └── ThisIsDDDDD
└── ThisIsDDDDD

指定 one or more upper case characters .即 [[:upper:]]##使用 zsh 的扩展通配符(zmv 使用)。 ##类似于正则表达式 +量词。单#是 zero or more , 类似于正则表达式 * .

zmv -n -Q '(**/)(*[[:upper:]]*)(/)' '${1}${(L)${2//(#b)([[:upper:]]##)/-$match[1]}#-}'

或者，单独转换前导大写字符而不是删除首字母 -然后:

${1}${(LM)2##[[:upper:]]#}${(L)${2##[[:upper:]]#}//(#b)([[:upper:]]##)/-$match[1]}
