As per Franklin's solution, all the records present in your file will be extracted into their corresponding output files.

Suppose if you have 2009,2008,2010,2007 then you will be having four output files. And you can ignore the source file completly as all records have been considered.

Please explain your requirement more specific if this is not expected.

Hello kumaran 5555,

The file i have is on live ie every time data enters to this file . This file is exceeding in size .So i have to cut the lines with last years to another file.

If that is the case like a log file and logs are written by another process continuously , then you may have to consider how the log writing is implemented before discarding its content to avoid data loss.

Thats ok kumaran, data loss is negligible, can we do this ? (grep+cut+paste)

thanks

To extract the records of 2009 you can add a condition like:
Code:
awk -F"[/:]" '$3=="2009" {print > "file_" $3}' file1

The requirement is to remove it from the source file after extracting records.

The source file may have been opened by another process for logging.

The actual requirement is to keep the log file size low by archiving the logs to different files.

Please suggest.

But the source file(file1) still have the extracted data!! How could we remove it from the source file at the same time.
