Question

我是Unix命令的新手，想知道下面做的脚本。

需要阅读应用程序日志并在最后半小时内提取所有错误。
获取每个错误的唯一计数。
将错误计数邮寄给团队。

采取的步骤：我已经使用grep读取了关键字错误并写入单独文件的文件。给予文件许可。

感谢您的帮助。

代码段：

#!/bin/sh
cd Service/apache-tomcat-7.0.33/logs
for file in catalina.out; do
grep "ERROR" $file >error.txt
done
chmod 0777 error.txt

我无法写出完整的剧本，因为我并不完全清楚你想要什么，但这是一个策略。

grep文件中的字符串＆＃39; ERROR＆＃39; （看起来你已经这样做过了。）
使用＆＃39; cut -d＆＃39; ＆＃39; -f4提取第四个空格分隔字段（yyyService）。
将输出换成sort，然后使用uniq -c来获取计数。
将结果传递给＆＃39; mail＆＃39;

所以，你最终会得到这样的东西：

grep ERROR /shipmentService/apache-tomcat-7.0.33/logs/catalina.out | cut -d ' ' -f4 | sort | uniq -c | mail -s "This is the subject" mail@example.com
