递归bash脚本，在Mac/Linux上用特定规则重命名文件和文件夹

Question

希望你们一切都好！

我是在完成这个相对简单的任务，但我没有得到最佳的结果，所以我需要你的帮助。

设想情况：

我有以下文件和文件夹(目录)结构：

.
├── nested-test-folder-1
│   ├── nested\ test\ file\ 1.txt
│   ├── nested\ test\ file\ 2\ tag1.txt
│   ├── nested\ test\ file\ 3\ tag3.txt
│   └── nested\ test\ file\ 4\ tag2.txt
├── nested-test-folder-2-tag1
│   ├── nested\ test\ file\ 5.txt
│   ├── nested\ test\ file\ 6\ tag1.txt
│   ├── nested\ test\ file\ 7\ tag3.txt
│   └── nested\ test\ file\ 8\ tag2.txt
├── nested-test-folder-3\ tag3
│   ├── nested\ test\ file\ 10\ tag1.txt
│   ├── nested\ test\ file\ 11\ tag3.txt
│   ├── nested\ test\ file\ 12\ tag2.txt
│   └── nested\ test\ file\ 9.txt
├── test\ file\ 13.txt
├── test\ file\ 14\ tag1.txt
├── test\ file\ 15\ tag3.txt
└── test\ file\ 16\ tag2.txt

我试图编写一个递归bash脚本来相应地重命名文件和文件夹：

-如果文件/文件夹包含"tag1“或"tag2”，则将其替换为新的"tag3".

-如果文件/文件夹不包含"tag1“或"tag2”，并且不包含"tag3"，则在其名称.中添加"tag3“。

- -必须在文件/文件夹名称的末尾添加"tag3“，如果文件必须在文件扩展名之前添加。

- -为了示例起见，所有文件扩展名都是".txt“，但在实际情况下，它们可以是任何东西，因此需要考虑这一点。

-脚本必须忽略隐藏文件和文件夹(。然后..。)、dotfiles (.zshrc等)、

您可以在我的git中快速查看这个文件的历史，看看我尝试了什么：

v0.1.sh

脚本

总结一下我迄今所做的尝试：

尝试1-一次做所有的事情：

#!/bin/bash

set -e

declare -a STRINGS_TO_REPLACE
STRINGS_TO_REPLACE=("tag1" "tag2")
STRING_TO_ADD_IF_NOT_PRESENT="tag3"

rename_files_and_folders() {
    while IFS= read -r -d '' n; do
        for current_string in "${STRINGS_TO_REPLACE[@]}" ;
        do
            if [[ "$n" == *"$current_string"* ]] || ! [[ "$n" =~ .*"$STRING_TO_ADD_IF_NOT_PRESENT".* ]]; 
            then
                rename -d "$current_string" "$n"
                break;
            fi
        done
        # echo "$n"
    done < <(find . \( -depth -type d -path '*/\.*' -prune -o -not -name '.*' \) -print0)
}

rename_files_and_folders

我得到的输出让我相信它首先重命名了一个dir，然后尝试使用dir的旧名称重命名其中的文件，所以我尝试将文件的重命名和dir分割成不同的函数。我还认为，首先从所有文件和文件夹中删除"tag1“和"tag2”可能更容易一些，然后再到处添加"tag3“。

尝试2-尝试分别处理文件和文件夹(目录)：

#!/bin/bash

set -e

declare -a STRINGS_TO_REPLACE
STRINGS_TO_REPLACE=("tag1" "tag2")
STRING_TO_ADD_IF_NOT_PRESENT="tag3"

rename_files_and_folders() {
    while IFS= read -r -d '' n; do

        # filename="${n##*/}"
        # currentfile="${n#.}"

        # if [[ -f "$n" ]] && [[ ! -d "$n" ]];
        # then

            for current_string in "${STRINGS_TO_REPLACE[@]}" ;
            do
                if [[ "$n" == *"$current_string"* ]]; 
                then
                    echo "Will rename $n"
                    test -e "$n" &&
                        rename -d "$current_string" "$n"
                    break;
                fi
            done

        # fi


    done < <(find . \( -type f -name "[!.]*" \) -print0)
}

rename_files_and_folders

rename_folders_and_dirs() {
    while IFS= read -r -d '' n; do


        if [[ -d "$n" ]];
        then

        for current_string in "${STRINGS_TO_REPLACE[@]}" ;
        do
            if [[ "$n" == *"$current_string"* ]]; 
            then
                echo "Will rename $n"
                test -e "$n" &&
                    rename -d "$current_string" "$n"
                break;
            fi
        done

        fi

    done < <(find . \( -depth -name "[!.]*" \) -print0)
}

rename_folders_and_dirs

当运行"Try 2“版本时，我得到以下输出：

Will rename ./test-data-files-and-folders-1/nested-test-folder-1/nested test file 2 tag1.txt
Will rename ./test-data-files-and-folders-1/nested-test-folder-1/nested test file 4 tag2.txt
Will rename ./test-data-files-and-folders-1/test file 14 tag1.txt
Will rename ./test-data-files-and-folders-1/nested-test-folder-2-tag1/nested test file 8 tag2.txt
Can't rename './test-data-files-and-folders-1/nested-test-folder-2-tag1/nested test file 8 tag2.txt' to './test-data-files-and-folders-1/nested-test-folder-2-/nested test file 8 tag2.txt': No such file or directory
Will rename ./test-data-files-and-folders-1/nested-test-folder-2-tag1/nested test file 5.txt
Can't rename './test-data-files-and-folders-1/nested-test-folder-2-tag1/nested test file 5.txt' to './test-data-files-and-folders-1/nested-test-folder-2-/nested test file 5.txt': No such file or directory
Will rename ./test-data-files-and-folders-1/nested-test-folder-2-tag1/nested test file 6 tag1.txt

Will rename ./test-data-files-and-folders-1/nested-test-folder-2-tag1/nested test file 7 tag3.txt
Can't rename './test-data-files-and-folders-1/nested-test-folder-2-tag1/nested test file 7 tag3.txt' to './test-data-files-and-folders-1/nested-test-folder-2-/nested test file 7 tag3.txt': No such file or directory
Will rename ./test-data-files-and-folders-1/test file 16 tag2.txt
Will rename ./test-data-files-and-folders-1/nested-test-folder-3 tag3/nested test file 12 tag2.txt
Will rename ./test-data-files-and-folders-1/nested-test-folder-3 tag3/nested test file 10 tag1.txt

在我看来，它似乎是首先重命名一个dir，然后尝试用一个旧的引用重命名文件，而我似乎无法绕过它。另外，find函数中的过滤器--一个仅用于文件，另一个用于文件夹--由于某种原因似乎无法工作。

其他我试过的比特和鲍勃：

## getting just the name of the file
filename="${n##*/}"

## removing the preceding dot
currentfile="${n#.}"

## filtering for just files and not dirs and vice versa
if [[ -f "$n" ]] && [[ ! -d "$n" ]];
then
    # ...
fi

任何帮助和建议都是非常感谢的！

谢谢!
