Now lets say if want to get text between two date Nov 17 to Nov 28...
How can i get that...:confused:

2 
 sed '/pattern/r second_file' file

Check if -i in place is supported by your sed

Is the other file of a similar format (ie leading date+time) and if so, should the extracted block of lines be merged with the records in the other file in date order, or just appended to the end?

If your after something quite simple and both the from and to dates exist in the file a simple sed script will get the data:

 sed -n '/Nov 17/,/Nov 26/p' logfile

Do you have GNU date on your system? Try:

 $ date --date "Nov 18"

Can we assume the files are already sorted in date+time order?
