抓取SHELL日誌中DB2錯誤

抓取SHELL日誌中DB2錯誤

日常工作中，使用腳本處理DB2數據會記錄些日誌，有時可能會對日誌文件提取是否有報錯信息，本文即時對日誌文件的報錯信息進行的提取。

#! /bin/awk -f

#生成變量
BEGIN {
 i=1
}

#匹配以SQL0開頭SQLSTATE爲結尾的行，把匹配的行賦值給數組stu
/^SQL0/{t=1}{
 if(t)s=length(s)?s"\n"$0:$0
}
/SQLSTATE/{
 t=0;
 stu[i]=s;
 i++;
 s=""
}

#輸出STU
END {
 a=1
 do
 {
  print stu[a]
  ++a;
 }while(a<=length(stu))
}

下面是執行腳本：

[root@ETL TEST]$ ./code1.sh /tmp/DB2_test.log
