问题描述
我有一个格式一些包罗万象的日志文件如下:
时间戳事件摘要
富细节
账户名:用户A
酒吧更多详情
时间戳事件摘要
巴兹细节
账户名:用户B
qux更多详情
时间戳等。
我想搜索用户B
日志文件,如果找到,从preceding时间戳回响(但不包括)以下的时间戳。有可能会几个事件匹配我的搜索。这将是很好呼应某种 --- ---启动
和 - 完 -
周围的每场比赛。
这将是完美的 pcregrep -M
,对不对?问题是,的GnuWin32的 pcregrep
与多行正则表达式搜索大文件死机,而这些包罗万象的日志可以是100兆以上。
我已经试过
我的hackish的解决方法迄今为止涉及到使用的grep -B15 -A30
来找到匹配的线条和打印周围的内容,然后通过管道将现在更容易管理的块到 pcregrep
为抛光。问题是,一些事件是小于十行,而有些则是30个或更多;而我得到的地方遇到较短的事件,一些意想不到的结果。

有没有更好的方法来做到这一点?我遇到那些看起来有点意思的 AWK

语法。有什么建议?
埃德莫顿建议我提供一些例如日志和期望的输出。

这是所有你需要用GNU AWK(对于IGNORECASE):
$猫tst.awk
功能prtRecord(){
如果(记录〜正则表达式){
printf的--------纪录%起始D --------%S,++ numRecords,ORS
printf的%S,记录
printf的---------纪录%d个---------%s%S结束,numRecords,ORS,ORS
}
记录=
}
BEGIN {IGNORECASE = 1}
/ ^ [[:数字:]] + - [[:数字:]] + - [[:数字:]] + / {prtRecord()}
{纪录=记录$ 0个ORS}
END {prtRecord()}
或任何AWK:
$猫tst.awk
功能prtRecord(){
如果(tolower的(记录)〜tolower的(正则表达式)){
printf的--------纪录%起始D --------%S,++ numRecords,ORS
printf的%S,记录
printf的---------纪录%d个---------%s%S结束,numRecords,ORS,ORS
}
记录=
}
/ ^ [[:数字:]] + - [[:数字:]] + - [[:数字:]] + / {prtRecord()}
{纪录=记录$ 0个ORS}
END {prtRecord()}
您会在UNIX上运行它无论哪种方式:
$ awk的正则表达式-v = user6q -f tst.awk文件
我不知道Windows的语法,但我希望它是非常相似,如果不相同的。
请注意在脚本中使用tolower的()来作出比较小写的两侧,与之匹配的是不区分大小写。如果你可以在搜索正则表达式这是正确的情况下,而不是传球,那么你不需要tolower的调用()比较的两边。 NBD,它可能只是加速脚本略有上升。
$ awk的正则表达式-v = user6q -f tst.awk文件

I have some catchall log files in a format as follows:
timestamp event summary
foo details
account name: userA
bar more details
timestamp event summary
baz details
account name: userB
qux more details
timestamp etc.
I would like to search the log file for userB
, and if found, echo from the preceding timestamp down to (but not including) the following timestamp. There will likely be several events matching my search. It would be nice to echo some sort of --- start ---
and --- end ---
surrounding each match.
This would be perfect for pcregrep -M
, right? Problem is, GnuWin32's pcregrep
crashes with multiline regexps searching large files, and these catch-all logs can be 100 megs or more.
What I've tried
My hackish workaround thus far involves using grep -B15 -A30
to find matching lines and print surrounding content, then piping the now more manageable chunk into pcregrep
for polishing. Problem is that some events are less than ten lines, while others are 30 or more; and I'm getting some unexpected results where the shorter events are encountered.
:parselog <username> <logfile>
set silent=1
set count=0
set deez=20\d\d-\d\d-\d\d \d\d:\d\d:\d\d
echo Searching %~2 for records containing %~1...
for /f "delims=" %%I in (
'grep -P -i -B15 -A30 ":\s+\b%~1\b(@mydomain\.ext)?$" "%~2" ^| pcregrep -M -i "^%deez%(.|\n)+?\b%~1\b(@mydomain\.ext|\r?\n)(.|\n)+?\n%deez%" 2^>NUL'
) do (
echo(%%I| findstr "^20[0-9][0-9]-[0-9][0-9]-[0-9][0-9].[0-9][0-9]:[0-9][0-9]:[0-9][0-9]" >NUL && (
if defined silent (
set silent=
set found=1
set /a "count+=1"
echo;
echo ---------------start of record !count!-------------
) else (
set silent=1
echo ----------------end of record !count!--------------
echo;
)
)
if not defined silent echo(%%I
)
goto :EOF
Is there a better way to do this? I've come across an awk
command that looked interesting, something like:
awk "/start pattern/,/end pattern/" logfile
... but it would need to match a middle pattern as well. Unfortunately, I'm not that familiar with awk
syntax. Any suggestions?
Ed Morton suggested that I supply some example logging and expected output.

This is all you need with GNU awk (for IGNORECASE):
$ cat tst.awk
function prtRecord() {
if (record ~ regexp) {
printf "-------- start of record %d --------%s", ++numRecords, ORS
printf "%s", record
printf "--------- end of record %d ---------%s%s", numRecords, ORS, ORS
}
record = ""
}
BEGIN{ IGNORECASE=1 }
/^[[:digit:]]+-[[:digit:]]+-[[:digit:]]+/ { prtRecord() }
{ record = record $0 ORS }
END { prtRecord() }
or with any awk:
$ cat tst.awk
function prtRecord() {
if (tolower(record) ~ tolower(regexp)) {
printf "-------- start of record %d --------%s", ++numRecords, ORS
printf "%s", record
printf "--------- end of record %d ---------%s%s", numRecords, ORS, ORS
}
record = ""
}
/^[[:digit:]]+-[[:digit:]]+-[[:digit:]]+/ { prtRecord() }
{ record = record $0 ORS }
END { prtRecord() }
Either way you'd run it on UNIX as:
$ awk -v regexp=user6q -f tst.awk file
I don't know the Windows syntax but I expect it's very similar if not identical.
Note the use of tolower() in the script to make both sides of the comparison lower case so the match is case-insensitive. If you can instead pass in a search regexp that's the correct case, then you don't need to call tolower() on either side of the comparison. nbd, it might just speed the script up slightly.
$ awk -v regexp=user6q -f tst.awk file
