我想提取完整的URL（一行中的完整URL）：

多行URL是我的问题。例如，我尝试了：

awk'{print$9}'

---

提前感谢您的帮助

您可以使用此awk命令：

awk -F '[[:blank:]]*\\|[[:blank:]]*' 'NR<3 || NF<5{next}
   $2{if (url) print url; url=$5; next}
   {url=url $5}
   END{print url}' file

---

调整用于生成此输出的sql语句更有意义

awk -F '[[:blank:]]*\\|[[:blank:]]*' 'NR<3 || NF<5{next}
   $2{if (url) print url; url=$5; next}
   {url=url $5}
   END{print url}' file
