Question

我需要很少的代码帮助。我需要的是“if语句”用grep或其他命令编码计数在文件中分别重复多少次。文件竞赛是：

2011/05/04 21:47:37 45992299 c blabla (xxx/xxx/xx:xxx): invalid (0 ms) (of 0 avail 0) - CHANNEL 1 (0,8W) (invalid SID)

如果单词（模式）“未找到”在每一行中重复一次（如示例文件中）并且如果达到10次，那么请完成（我会发出命令）

这部分代码在实时当前文件中监控是否有任何可能性？我的意思是如果用crond开始一次连续监视我的文件？

修改的现在我看到我需要更多的脚本而不是其他的东西.. 如何实现我的脚本所有时间（实时）从文件中查看最后10行？

寻求帮助！

Answer 1

类似

#!/bin/bash

while ${cleanLogFile:-true} ; do
   if (( $(grep -c "not found" logFile) > 9 )) ; then
       echo "Too many 'not found's in logFile"
       # do your stuff here
       cleanLogFile=false
    fi

完成

我希望这会有所帮助。

当且仅当有10个或更多连续行“未找到”时，此AWK代码才会打印出该消息：

! /not found/ {
    if (count >= 10) {
        print "More than 10 lines found"
    }
    count = 0
}
/not found/ {
    ++count
}

END {
    if (count >= 10) {
        print "More than 10 lines found"
    }

如何用grep或awk计数，模式是否分别出现x次（一个接一个）
