--//前面的测试,链接:http://blog.itpub.net/267265/viewspace-2771267/ =>[20210507]dump library_cache.txt
--//如何写简单脚本实现1个Bucket下,有2行^  LibraryHandle:的输出呢? 把转储文件拷贝出来,在家里做一个尝试.

C:\other> grep -E "^Bucket:|^  LibraryHandle:|^$" book_ora_12044_0003.trc >aa.txt

--//真心话,写了一个多小时,代码如下:

C:\other>cat a1.awk
BEGIN {
line = 0
bucket = ""
library = ""
}

/^Bucket:/,/^$/ {
    if ($0 ~ /^Bucket:/) {
        line=0
        bucket=$0
    }

    if ($0 ~ /^  LibraryHandle:/ && line == 0 ) {
        line=NR
        library=$0
    }

    if ($0 ~ /^  LibraryHandle:/ && line != 0 ) {
        if ( line+1 == NR ) {
            printf "%s\n" ,bucket
            printf "%s\n" ,library
            printf "%s\n\n" ,$0
            line = 0
            bucket = ""
            library = ""
        }
    }
}

--//如果要写脚本实现1个Bucket下,有3行^  LibraryHandle:的输出,代码还给重新写.放弃,不擅长awk的脚本语言.
