我试图找到 的所有实例"type":"FollowEvent"
,然后在这些实例中,如果字符串"actor":
后面没有跟随,则捕获紧随 后面{
的字符串。否则,捕获紧随 后面的包含在 中的字符串。"
"actor":
"
"login:"
到目前为止我所拥有的:
zgrep -e '"type":"FollowEvent"' /path/to/dir/* | zgrep -o '"actor":(?!{)*' | cut -f2- -d: | cut -d',' -f1 > results_file.txt
编辑:这zgrep
是做什么的:
对于 /path/to/dir 中的所有文件,对于包含"type":"FollowEvent"
, find"actor:"
后不跟有 的所有行{
。然后取出 the 之后:
和 next 之前的所有内容,
。将结果放入results_file.txt
.
编辑显示数据:
正在被 grep 的文件中的一行可能如下所示:
{"repo":{"url":"https://url","name":"/"},"type":"FollowEvent","public":true,"created_at":"2011-05-29","payload":{"target":{"gravatar_id":"73","id":64,"repos":35,"followers":58,"login":"username3"}},"actor":{"gravatar_id":"06","id":439,"url":"https://url","avatar_url":"https://.png","login":"username4"},"id":"14"}
或者像这样:
{"repo":{"url":"https://url/","name":"/"},"type":"FollowEvent","public":true,"created_at":"2011-04-01","payload":{"target":{"gravatar_id":"40","repos":2,"followers":1,"login":"username2"},"actor":"username1","actor_gravatar":"de4"},"actor":{"gravatar_id":"de4","id":716,"url":"https://url","avatar_url":"https://.png","login":"username2"},"id":"12"}
答案1
可以使用以下命令从两个 JSON 文档中获取login
下面列出的用户名:target
jq
$ jq -r '.payload.target.login' file1.json
username3
同样,可以有login
以下内容:actor
$ jq -r '.actor.login' file1.json
username4
如果您想让输出以 为条件(如果不是,type
则不产生任何内容):type
FollowEvent
jq -r 'select(.type == "FollowEvent") | .actor.login' file1.json
