请教，awk和grep怎么实现将匹配与打印

_寒_CU

问题：如果匹配到行包含 /bin/bash ./ifstat_monitor.sh则就打印下对应的IP一行
文本：
ps -ef |grep ifstat_monitor.sh
root     25356 30188  0 16:42 ?        00:00:00 /bin/bash ./ifstat_monitor.sh

root     30188     1  0 Aug16 ?        00:13:03 /bin/bash ./ifstat_monitor.sh
192.168.158.36  OK

ps -ef |grep ifstat_monitor.sh
root     13375     1  0 Aug16 ?        00:12:57 /bin/bash ./ifstat_monitor.sh

root     23141 23139  0 16:42 ?        00:00:00 bash -c ps -ef |grep ifstat_monitor.sh
root     23151 23141  0 16:42 ?        00:00:00 grep ifstat_monitor.sh
192.168.158.37  OK

ps -ef |grep ifstat_monitor.sh
root     44449 44447  0 16:42 ?        00:00:00 bash -c ps -ef |grep ifstat_monitor.sh
root     44451 44449  0 16:42 ?        00:00:00 grep ifstat_monitor.sh
192.168.158.39  OK
.......
ps -ef |grep ifstat_monitor.sh
root     31876 42910  0 16:43 ?        00:00:00 /bin/bash ./ifstat_monitor.sh
root     31893 31852  0 16:43 ?        00:00:00 bash -c ps -ef |grep ifstat_monitor.sh
root     31904 31893  0 16:43 ?        00:00:00 grep ifstat_monitor.sh
root     42910     1  0 Aug16 ?        00:12:55 /bin/bash ./ifstat_monitor.sh
192.168.158.161 OK

想得到如下：
192.168.158.36  OK
192.168.158.37  OK
.....
192.168.158.161  OK

是不是所有"OK"的行?

1. awk -vRS= '$0=$(NF-1) FS $NF' file

不，首先得匹配到 包含  "/bin/bash ./ifstat_monitor.sh" 行 ，才打印对应的IP一行

_寒_CU

1. grep "/bin/bash ./ifstat_monitor.sh" -A3|grep -oP '^[\d. ]+\w+'
