有推荐的 shell 命令来执行此操作吗？我在运行 10.9 的 Mac 上考虑了以下 sed 命令，但遇到了错误。

$ gsed -e 's/.*SRC="\/Repository\([^"]*\)".*/\1/p{r File1.html' -e 'd}' File2.txt

答案1

假设包含EntityID一个唯一的字符串来标识 File2.txt 中的正确 URL，这不仅适用于您的示例：

sed '\_^/getimage.dll.*gif$_{H;d}
  G;s/<img src="[^"]*EntityID=\([^&]*\)&[^"]*"\(.*\)\n\(\/getimage[^\n]*\1[^.]*.gif\).*/<img src="\3"/;s/\n.*//' File2.txt File1.html

如果需要，请寻求解释。
