1）我有一个名为 version.txt 的日志文件，需要过滤掉所有带有关键字“took ?? ms”的单词。每个日志条目的 ms 之前的数字（“took ?? ms”）各不相同。

输出应如下所示：

took 4 ms
took 3 ms
took 4 ms
took 5 ms

2）也可以列出> 100的记录。即。它应该列出超过 100 的值。输出应该是这样的；

took 100 ms
took 110 ms
took 450 ms

答案1

这个你可以尝试：

grep -oP "took [[:digit:]]{3,} ms" file

输出：

took 100 ms
took 110 ms
took 400 ms

谢谢。是否也可以列出日期/时间？像这样的输出：

2020-03-11 06:19:29.857 花了 100 毫秒

2020-03-11 06:19:29.857 耗时 110 毫秒

假设所有记录具有相同的格式，使用cut,sed和 更容易grep：

cut -d' ' -f1,2,15-17 file | sed 's/*//g' | grep -P "took [[:digit:]]{3,} ms"

2020-03-11 06:19:29.857 took 100 ms
2020-03-11 06:19:29.857 took 110 ms
2020-03-11 06:19:29.857 took 400 ms

答案2

您可以awk使用以下方式做到这一点：

awk -F '**' '{print $2}' input_file

要添加时间和日期，您可以使用以下内容：

awk -F '**' '{split($1,a," ");print a[1]" " a[2]" " $2}' input_file
