我有一个字符串,如下所示:
{"projects":{"1633045839405":
{"name":"goal2","created":"2012-11-10T19:10:06Z","modified":"2012-11-10T19:10:06Z" ,"customMetadata":{}},"1976708868731":{"name":"goal1","created":"2012-11-11T11:35:12Z","modified":"2012-11-11T11:35 :12Z","customMetadata":{}}}}
我想使用 grep 来获取子字符串 1633045839405。
我怎么能用 grep 做到这一点?
谢谢!
