Question

专家，我是UNIX的初学者。

我有一个文件NewFile.txt，其中包含以下内容：

DBLogFile.txt:Fri May 8 08:18:20 EDT 2014 (T76:Partition:User:PasswordAdapter:1uh8fl:buyerserver10) (jdbc:WARN) [ID6726]: Database connection pool size for database: Transaction.Schema1(DB details) (Login Param) exceeded 25 for connection Transaction.Schema1(DB details) (Login Param).  Current size is 26. Some text.

Current size is 26.

如果数据库连接数超过25并且显示当前大小，则日志基本上会发出警告。

我有以下代码片段来收集DBLogFileName（DBLogFile.txt），时间（Fri May 16 08:19:48 EDT 2014）和当前数据库大小（26）

while read -r line; do 

    echo "...........";

    COUNTSTR=`echo $line | awk -F "Current size is " '{print $2}'`;

    DBCOUNT=`echo $COUNTSTR | awk '{ print substr($1,0,2) }'`;

    echo DBCOUNT is $DBCOUNT;
    echo DBCOUNT is $DBCOUNT >> $LOGFILE;

    NODE=`echo $line | awk -F "Log.txt:" '{print $1}'`;

    echo NODE is $NODE;
    echo NODE is $NODE >> $LOGFILE;

    WHEN=`echo $line | awk -F "Log.txt:" '{print substr($2,0,28)}'`;

    echo WHEN is $WHEN;
    echo WHEN is WHEN >> $LOGFILE;

    echo "...........";

done < NewFile.txt

我是否坚持使用awk的最佳做法？有没有办法改善这个？我想收集：filename, time and size

让我们从这开始：

$ awk -v OFS=" - " '{
    split($1,a,/:/)
    name=a[1]
    time=a[2]" "$2" "$3" "$4" "$5" "$6
    sub(/.*Current size is /,"")
    size=$1+0
    print name, time, size
}' file
DBLogFile.txt - Fri May 8 08:18:20 EDT 2014 - 26

那很接近吗？还有什么需要让它完全符合你的要求？

改进逻辑以使用awk在字符串中查找一组字符
