我想提取完整的网址（一行中的完整网址）：

hxxp://thebackpack.fr/wp-content/themes/salient/wpbakery/js_composer/assets/lib/prettyphoto/images/prettyPhoto/light_rounded/66836487162.txt
hxxp://thebackpack.fr/
hxxp://thebackpack.fr/wp-content/themes/salient/wpbakery/js_composer/assets/lib/prettyphoto/images/prettyPhoto/light_rounded/

多行网址是我的问题。我试过例如：awk '{print $9}'

提前感谢您的帮助！

Answer 1

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

<强>输出：
