Unix正则表达式与grep匹配

时间：2015-03-07 14:24:00

标签： parsing unix curl grep

我是unix控制台中使用正则表达式的新手，所以我有一个问题。我想解析一个网页并收集包含锚标记的行，并将它们放在单独的文件中。

所以这不打印任何东西：

curl "https://www.google.ru/?gfe_rd=cr&ei=9fv6VMq4CoiFZIezgaAN#newwindow=1&q=site:https:%2F%2Ftwitter.com%2Fclimagic" | grep '<a '

HTML卷曲打印：

对于扩展正则表达式使用egrep，据我所知你只想拉锚标记试试：
curl <your link> | egrep -o '<a.*/a>' '
-o：仅打印行
的匹配部分 '<a.*/a>'：在锚标记之间提取任何内容
