写一个脚本合并相同名称的文件至新建文件夹中

[!前言]
有时候会碰到这种情况，一个文件夹中存在大量文件，有些文件名称相同但是文件类型不同。如果想要将名称相同的文件保存至一个新建的文件夹中，这个文件夹以共同的名称命名，应该如何操作？

类似结构如图

目标是创建这是AAA,这是BBB,这是CCC文件夹并将相同名称的文件移动进去

创建脚本

如果是windows则新建一个文件并重新命名为merge_files.sh,如果是linux则nano merge_files.sh或者vim merge_files.sh

输入以下内容

#!/bin/bash

# 列出所有文件
list_files() {
    local directory="$1"
    find "$directory" -maxdepth 1 -type f
}

# 显示文件列表
display_files() {
    local files=("$@")
    echo "List of files:"
    for file in "${files[@]}"; do
        echo "$file"
    done
}

# 合并文件
merge_files() {
    local files=("$@")
    declare -A file_dict
    local errors=()

    # 分类文件
    for file in "${files[@]}"; do
        base_name=$(basename "$file" | sed 's/\.[^.]*$//')
        if [[ -z "${file_dict["$base_name"]}" ]]; then
            file_dict["$base_name"]=""
        fi
        file_dict["$base_name"]+="$file;"
    done

    # 创建新文件夹并移动文件
    for base_name in "${!file_dict[@]}"; do
        IFS=';' read -r -a file_list <<< "${file_dict["$base_name"]}"
        new_folder="$(dirname "${file_list[0]}")/$base_name"
        mkdir -p "$new_folder"
        for file in "${file_list[@]}"; do
            mv "$file" "$new_folder" 2>/dev/null
            if [ $? -ne 0 ]; then
                errors+=("$file")
            fi
        done
        echo "Files moved to $new_folder"
    done

    # 列出出错的文件
    if [ ${#errors[@]} -gt 0 ]; then
        echo "The following files could not be moved:"
        for error in "${errors[@]}"; do
            echo "$error"
        done
    else
        echo "All files moved successfully."
    fi
}

# 主函数
main() {
    if [ $# -ne 1 ]; then
        echo "Usage: $0 <directory-path>"
        exit 1
    fi

    local directory="$1"

    if [ ! -d "$directory" ]; then
        echo "Error: Directory $directory does not exist."
        exit 1
    fi

    mapfile -t files < <(list_files "$directory")
    display_files "${files[@]}"

    read -p "Do you want to merge files with the same name but different extensions? (Y/N): " choice
    if [[ "$choice" == "Y" || "$choice" == "y" ]]; then
        merge_files "${files[@]}"
    else
        echo "No files were merged."
    fi
}

# 运行主函数
main "$@"
