請(qǐng)教個(gè)grep正則問題

都在一行的文本內(nèi)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為關(guān)鍵詞，grep輸出
{"BoltId":"crash_hour_stat_crs","Emitted":"0","Send_TPS":"0.000","Recv_TPS":"0.000","acked":"0"}

求個(gè)grep正則

回復(fù) 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

復(fù)制代碼

這樣?

Auroracxy

樓上兩種都可以，感謝

我愛你我的菜

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