Question

我如何只提取一个在线CLine（带有status_icon_online）？我可以通过以下方式提取所有clines：

cat test.txt | sed -n 's:.*">C\(.*\)</a>.*:\1:p'

但我只想在线，结果应该是这样的：

C：free.cccamlux.co 21900 FREEAC5p08w cccamlux.com

我的test.txt文件：

> <tr>
<td valign="middle">

Answer 1

也许你可以使用它;

 awk '/<tr>/ {printf "\n%s\n",$0;next} {printf "%s ",$0}' test |  grep -o -P '(?<=Cline).*(?=online)'  |  grep -o -P '.*(?=">C)'

awk命令;合并文件中<tr>和</tr>之间的行。

先是grep;只在Cline和在线之间获取文本

最后一次grep;只获取网址

测试;

$ awk '/<tr>/ {printf "\n%s\n",$0;next} {printf "%s ",$0}' test |  grep -o -P '(?<=Cline).*(?=online)'  |  grep -o -P '.*(?=">C)'
C: free.cccamlux.co 21900 FREEAC5p08w cccamlux.com

如何使用sed / grep在两个单词之间提取条件？
