linux - 需要帮助从目录中获取多个日志文件并 grep 错误

Question

这就是我到目前为止的问题，我的问题是如何在所有日志文件所在的脚本中添加目录

#!/bin/bash
while true ; do
    tail ~/Path
    grep -o 'ERROR No appender named [MicromuseAppender] could be found' ' /dyn/logfiles/ (path)' &> /dyn/logfiles/.log
    if [ $? -eq 0 ] ; then
        echo Error found
        break
    fi
    sleep 10
done

Answer 1

转到目标文件夹并从所有文件中查找

grep 'ERROR No appender named [MicromuseAppender] could be found' $PATH/*

输出是这样的

<Filename>:<line which contains the grep'ed string>

仅获取错误字符串至少出现一次的文件名。

grep 'ERROR No appender named [MicromuseAppender] could be found' $PATH/* | cut -f1 -d: | sort | uniq
