我正在尝试与

sed -n '/lastActiveTimes:/,/chatNotif/p' home.html | sed '1s/.*lastActiveTimes://; $s/chatNotif.*//' > end.json

但是没有用

推荐答案

如果您不介意使用 Perl ，则可以尝试:

if you do not mind using Perl you can try:

perl -lne 'print $& if /(?<=lastActiveTimes:).*?(?=,chatNotif)/g' home.txt  

它打印以下两个断言之间的所有内容: lastActiveTimes:和，chatNotif

It prints anything between these two assertions: lastActiveTimes: and ,chatNotif

ack -o '(?<=lastActiveTimes:).*?(?=,chatNotif)' home.txt
