linux - sed 提取给定日期之间的日志

Question

我正在尝试提取两个给定日期的日志。如果我指定像 Apr 02 15:21:28 这样的日期，代码工作正常，我的意思是如果知道确切的分钟和秒时间，但是代码会失败，因为我传递这样的值从 Apr 02 15* 到 Apr 04 15* 这里 15 是小时，实际上我想制作脚本，用户只需要在其中添加日期和时间(仅以小时为单位，没有分钟或秒)

> #!/bin/bash
read -p " enter the App name : " app
file="/logs/$app/$app.log"
read -p " Enter the Date in this Format --'10 Jan 20 or Jan 10 20' : " first
read -p " Enter the End time of logs : " end

if [ -f "$file" ]
then
    if grep -q "$first" "$file"; then
        final_first=$first
    fi
    if grep -q "$end" "$file"; then
        final_end=$end
    fi

        sed -n " /$final_first/,/$final_end/ "p $file >$app.txt

else
        echo "$app.log not found, Please check correct log name in deployer"
fi

示例数据:

Apr 07 12:39:15 DEBUG [http-0.0.0.0-8089-21] model.DSSAuthorizationModel - pathInfo : /about-ses 
Apr 07 12:39:15 DEBUG [http-0.0.0.0-8089-21] servlet.CasperServlet - Request about to be serviced by model: com.ge.oilandgas.sts.model.SessionValidModel 

Answer 1

我会使用带有内置日期时间解析或易于包含的模块的语言。例如，perl

first="Apr 07 12" 
end="Apr 08 00"
perl -MTime::Piece -sane '
    BEGIN {
        $first_ts = Time::Piece->strptime($first, "%b %d %H")->epoch;
        $end_ts = Time::Piece->strptime($end, "%b %d %H")->epoch;
    }
    $ts = Time::Piece->strptime(join(" ", @F[0..2]), "%b %d %T")->epoch;
    print if $first_ts <= $ts and $ts <= $end_ts;
' -- -first="$first" -end="$end" <<END

Apr 07 11:39:15 DEBUG [http-0.0.0.0-8089-21] model.DSSAuthorizationModel - pathInfo : /about-ses 
Apr 07 12:00:00 DEBUG [http-0.0.0.0-8089-21] model.DSSAuthorizationModel - pathInfo : /about-ses 
Apr 07 12:39:15 DEBUG [http-0.0.0.0-8089-21] model.DSSAuthorizationModel - pathInfo : /about-ses 
Apr 07 12:39:15 DEBUG [http-0.0.0.0-8089-21] servlet.CasperServlet - Request about to be serviced by model: com.ge.oilandgas.sts.model.SessionValidModel 
Apr 07 23:59:59 DEBUG [http-0.0.0.0-8089-21] servlet.CasperServlet - Request about to be serviced by model: com.ge.oilandgas.sts.model.SessionValidModel 
Apr 08 00:00:01 DEBUG [http-0.0.0.0-8089-21] servlet.CasperServlet - Request about to be serviced by model: com.ge.oilandgas.sts.model.SessionValidModel 
END

输出

Apr 07 12:00:00 DEBUG [http-0.0.0.0-8089-21] model.DSSAuthorizationModel - pathInfo : /about-ses 
Apr 07 12:39:15 DEBUG [http-0.0.0.0-8089-21] model.DSSAuthorizationModel - pathInfo : /about-ses 
Apr 07 12:39:15 DEBUG [http-0.0.0.0-8089-21] servlet.CasperServlet - Request about to be serviced by model: com.ge.oilandgas.sts.model.SessionValidModel 
Apr 07 23:59:59 DEBUG [http-0.0.0.0-8089-21] servlet.CasperServlet - Request about to be serviced by model: com.ge.oilandgas.sts.model.SessionValidModel 

<小时/>

根据您的代码，我将进行以下更改:

if ! [ -f "$file" ]; then
    echo "$app.log not found, Please check correct log name in deployer"
    exit 1
fi

grep -q "$first" "$file" && final_first="/$first/" || final_first='1'
grep -q "$end"   "$file" && final_end="/$end/"     || final_end='$'

sed -n "${final_first},${final_end}p" "$file" >"$app.txt"

它提供了 sed 范围、第一行和最后一行的默认地址。
