请教个grep正则问题

Auroracxy

都在一行的文本内容，
{"topology":{"Window":"600","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},"spout":{"SpoutId":"crash","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},"bolt":[{"BoltId":"crash_user_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"excep_stack_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"crash_act_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"isp_net_crash_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"user_search_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"crash_model_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"excep_user_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"crash_stack_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"__acker","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"crash_hour_stat_crs","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"cpu_mem_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"crash_hour_stack_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"excep_hour_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"crash_alert","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"},{"BoltId":"crash_os_stat","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"}]}

例如想用crash_hour_stat_crs为关键词，grep输出
{"BoltId":"crash_hour_stat_crs","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"}

求个grep正则

回复 1# Auroracxy

$ grep -oP '\{"BoltId":"crash_hour_stat_crs",[^}]+\}' FILE
{"BoltId":"crash_hour_stat_crs","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"}

   

我是一隻羊

1. grep -Eo '\{[^{]+crash_hour_stat_crs[^}]+}' inputfile

复制代码

这样?

楼上两种都可以，感谢

我爱你我的菜

cat test.txt | grep -E '{[^\{]+crash_hour_stat_crs[^\}]+}'
