You can use the following script to batch rename picture files on a Mac:

1. Batch script

#!/bin/bash

# 设置文件夹路径和要替换的字符串及其替换内容
folder_path="/您的/文件夹/路径"
old_string="要替换的字符串"
new_string="替换后的字符串"

# 进入文件夹路径
cd "$folder_path"

# 遍历文件夹中的所有图片文件
for file in *.jpg *.jpeg *.png *.gif *.bmp *.tiff *.heic; do
    if [[ -f "$file" ]]; then
        # 获取文件名和扩展名
        filename=$(basename "$file")
        extension="${filename##*.}"
        
        # 替换字符串并构建新文件名
        new_name="${filename/$old_string/$new_string}"
        
        # 重命名文件
        mv "$file" "$new_name"
        echo "已重命名 $file 为 $new_name"
    fi
done

echo "批量替换完成！"

Save the above code as a text file, for example replace_pngName.sh, then open a terminal and navigate to the folder where the script is located.

2. Give the script execution permission:

chmod +x replace_pngName.sh

3. Run the script:

./replace_pngName.sh

The script will traverse all image files in the specified folder, replace the specified string in the file name with a new string, and rename the file to the new name. Note that you can modify the folder paths, strings to replace and what to replace in the script as needed.

⚠️: Before running the script, be sure to back up your files in case something unexpected happens.
