startTime 和 endTime 之间的输出日志行

鉴于我有包含内容的日志文件app.log：

2018-08-29 07:43:17.123-0500 CDT [osb_02] [[ACTIVE] ExecuteThread: '14' for queue: 'weblogic.kernel.Default (self-tuning)'] INFO -

 [OSB Tracing] Outbound response was received.

我想获取我指定为参数的时间戳范围之间的日志行。

请注意，该日志行不仅仅是以时间戳开头的 1 行。该行之后有附加信息，直到出现具有不同时间戳的下一行。

所以在我们的例子中：

2018-08-29 07:43:17.123-0500 CDT [osb_02] [[ACTIVE] ExecuteThread: '14' for queue: 'weblogic.kernel.Default (self-tuning)'] INFO -
 [OSB Tracing] Outbound request was sent.

是 1 个日志行。

所以，我想执行some command 2018-08-29 07:44:00.000 2018-08-29 07:46:00.000 app.log将返回的内容

2018-08-29 07:44:18.789-0500 CDT [osb_02] [[ACTIVE] ExecuteThread: '14' for queue: 'weblogic.kernel.Default (self-tuning)'] INFO -
 [OSB Tracing] Outbound request was sent.


2018-08-29 07:44:18.779-0500 CDT [osb_02] [[ACTIVE] ExecuteThread: '28' for queue: 'weblogic.kernel.Default (self-tuning)'] INFO -
 [OSB Tracing] Outbound response was received.


2018-08-29 07:45:19.433-0500 CDT [osb_02] [[ACTIVE] ExecuteThread: '14' for queue: 'weblogic.kernel.Default (self-tuning)'] INFO -

 [OSB Tracing] Outbound response was received.

另请注意，参数不一定存在于日志文件中。

答案1

sed '1,/pattern1/d;/pattern2/,$d' app.log应该能解决问题

如果您希望它作为脚本按照您提到的方式运行，那么 ~/.bashrc 中的函数如下所示：

time_log() {
    pattern1=$1
    pattern2=$2
    file=$3
    sed "1,/$pattern1/d;/$pattern2/,$d" "$file"
}

然后你可以运行：

time_log "2018-08-29 07:44:" "2018-08-29 07:46:" app.log

编辑：

删除了不必要的cat

要包含第一行，最简单的方法就是grep在运行之前包含第一行sed：

time_log() {
    pattern1=$1
    pattern2=$2
    file=$3
    grep "$pattern1" "$file"
    sed "1,/$pattern1/d;/$pattern2/,$d" "$file"
}

sed如果有 sed 大师愿意插话的话，可能有更好的方法来做到这一点。
