批量替换某个目下所有包含的文件的内容

cd etc
sed -i "s/查找的内容/替换后的内容/g" `grep -rl "查找的内容" ./`

• 例如当前我需要将当前文件夹下所有子目录的所有子文件中的 cdn.jsdelivr.net/gh/zywvvd/HexoImages 字符串替换为 cdn.jsdelivr.net/gh/zywvvd/HexoFiles

  字符 / 需要用 \ 字符进行转义

sed -i "s/cdn.jsdelivr.net\/gh\/zywvvd\/HexoImages/gitee.com\/zywvvd\/HexoImages\/raw\/main/g" `grep -rl "cdn.jsdelivr.net\/gh\/zywvvd\/HexoImages" ./`

批量查找并替换任意文件夹下的文件内容。

sed -i "s/要找查找的文本/替换后的文本/g" `grep -rl "要找查找的文本" /任意文件夹`
