I am trying to fetch data between a range of time intervals from the log file. However, the complete data is not fetched for the end date.



Below is the command used:



 sed -n '/26/Nov/2018/,/30/Nov/2018/ p' /path/file.log


The data I am having in the above log file is somewhat like:



 192.168.0.123 - - [25/Nov/2018:13:24:59 +0530] "Data 1"

 192.168.0.123 - - [26/Nov/2018:13:24:59 +0530] "Data 2"

 192.168.0.123 - - [26/Nov/2018:13:25:09 +0530] "Data 3"

 192.168.0.123 - - [27/Nov/2018:13:25:09 +0530] "Data 4"

That's because you are using / both as a separator for the sed match command and as part of the string being matched. You need to escape the internal /. Try this instead:



$  sed -n '/26/Nov/2018/,/30/Nov/2018/ p' file.log 

 192.168.0.123 - - [26/Nov/2018:13:24:59 +0530] "Data 2"

 192.168.0.123 - - [26/Nov/2018:13:25:09 +0530] "Data 3"

 192.168.0.123 - - [27/Nov/2018:13:25:09 +0530] "Data 4"
