在unix中基于时间对数据进行Grep

Question

嗨，我想根据时间从文件中删除一些数据。因此，如果时间匹配，我想将文件中的所有特定行放入一个新文件：以下是我的文件格式：

    1 - - [22/Jul/2016:07:46:15 -0500] "POST abc HTTP/1.0" 200 679 93071
1 - - [22/Jul/2016:07:46:16 -0500] "POST abc HTTP/1.0" 200 679 100994
1 - - [22/Jul/2016:07:46:17 -0500] "POST abc HTTP/1.0" 200 679 102270
1 - - [22/Jul/2016:07:46:18 -0500] "POST abc HTTP/1.0" 200 679 103008
1 - - [22/Jul/2016:07:46:19 -0500] "POST abc HTTP/1.0" 200 679 109170
1 - - [22/Jul/2016:07:46:20 -0500] "POST abc HTTP/1.0" 200 679 101149
1 - - [22/Jul/2016:07:46:21 -0500] "POST abc HTTP/1.0" 200 679 24796
1 - - [22/Jul/2016:07:46:22 -0500] "POST abc HTTP/1.0" 200 679 93071
1 - - [22/Jul/2016:07:46:23 -0500] "POST abc HTTP/1.0" 200 679 100994
1 - - [22/Jul/2016:07:46:24 -0500] "POST abc HTTP/1.0" 200 679 102270
1 - - [22/Jul/2016:07:47:25 -0500] "POST abc HTTP/1.0" 200 679 103008
1 - - [22/Jul/2016:07:47:19 -0500] "POST abc HTTP/1.0" 200 679 109170
1 - - [22/Jul/2016:07:47:20 -0500] "POST abc HTTP/1.0" 200 679 101149

现在我想对时间在07:46:15到07:47:20之间的值进行grep

Answer 1

只需使用一个简单的正则表达式：

grep ":07:46:1[5-9]" file

这与07:46:15至：19之间的任何时间都匹配。

对于给定的输入，它返回：

1 - - [22/Jul/2016:07:46:15 -0500] "POST abc HTTP/1.0" 200 679 93071
1 - - [22/Jul/2016:07:46:16 -0500] "POST abc HTTP/1.0" 200 679 100994
1 - - [22/Jul/2016:07:46:17 -0500] "POST abc HTTP/1.0" 200 679 102270
1 - - [22/Jul/2016:07:46:18 -0500] "POST abc HTTP/1.0" 200 679 103008
1 - - [22/Jul/2016:07:46:19 -0500] "POST abc HTTP/1.0" 200 679 109170
1 - - [22/Jul/2016:07:46:15 -0500] "POST abc HTTP/1.0" 200 679 101149
1 - - [22/Jul/2016:07:46:15 -0500] "POST abc HTTP/1.0" 200 679 24796
