# 把当前目录下所有 PNG 转成 75% 质量的 JPG，并在原文件名后加 _quality75.jpg
find . -maxdepth 1 -type f -iname '*.png' -print0 | xargs -0 -I{} sh -c 'magick "$1" -background white -alpha remove -alpha off -strip -quality 85 "${1%.png}_q85.jpg"' _ {}

说明
• 使用 -background white -alpha remove -alpha off 处理透明背景，避免黑底；如需其他颜色，把 white 改成你想要的颜色值（如 “#1e1e1e”）。
• -strip 会移除元数据以进一步减小体积；若需保留 ICC/EXIF，删除 -strip。
• 质量 75 是偏中高的网页常用档位；需要更高或更小体积，调节 -quality。

Customizing the 'Created by' Author Name in Xcode

When you create a new file in Xcode, the IDE automatically adds a header comment that includes information like the filename, creation date, and author. By default, the author name is derived from your macOS system's full username. However, you might want to customize this for various reasons - perhaps you're sharing code publicly, working on a team project, or simply prefer a different name format.

This article explains multiple methods to customize the "Created by" author name in Xcode.

Understanding the File Header Template

When you create a new file in Xcode, you'll see a header comment like this:

// 定义一个异步函数来处理删除操作
async function clearCart() {
    // 使用更通用的属性选择器来找到所有商品项
    const cartItems = document.querySelectorAll('[class*="trade-cart-item-info"]');
    
    let deletedCount = 0;
    const totalItems = cartItems.length;
    
    console.log(`找到 ${totalItems} 个商品项`);
