我正在尝试使用 sed
sed -n '/lastActiveTimes:/,/chatNotif/p' home.html | sed '1s/.*lastActiveTimes://; $s/chatNotif.*//' > end.json
但不起作用
答案1
尝试下面的 sed 脚本。由于我不知道“home.html”的其余部分是什么样子，所以我只测试了您给出的具体情况。
sed ':r;$!N;$!br;s/.*lastActiveTimes:\(.*\),chatNotif:0.*/\1/' home.html > end.json
答案2
和grep：
grep -Poz 'lastActiveTimes:.*(?=,chatNotif:0)' home.html
-P- Perl 正则表达式-z- 将输入和输出数据视为行序列，每行以零字节终止
输出：
