Hi
Having a file as follows

Code:

==================================================
Date           Time         error code      server
======================================================
12-29-08    10:10        121221          server A
12-29-08    10:12        121221          server A
12-29-08    10:10        121221          server B
12-29-08    10:10        121221          server B

Need to remove the duplicate lines with the following conditions
if date=12-29-08 and server=server A .
Must delete the line with old time and keep the latest.

Anyone can suggest

Thanks in advance
