How to use agrep, a windows based version of the linux command line grep tool.
This example comes from finding lines related to a message in smartermail log files. Lets assume we are trying to find an email and track the actions our mail server did for that email. First I am going to filter the logs for the 16/6/2009 and return only the lines for a particular domain. To do this we copy the days log files into a /tmp directory and run the following:
D:\SmarterMail\Logs\tmp>agrep -k “domain.com” * > d:\smartermail\logs\tmp\out\out.txt
This will give us every line in all the files in the tmp directory relating to domain.com. We can then sift through this manually to find a row relating to the mail we need.
One of these lines looks like this:
2009.06.16-delivery.log: 10:36:11 Delivery started for webmaster@domain.com at 10:36:11 AM
Notice the reference number – this is carried through all logs for this particular email, so we can use that to find all log entries about this mail:
D:\SmarterMail\Logs\tmp>agrep -k “” * > d:\smartermail\logs\tmp\out\out.txt
This outputs all the lines with in them to the out.txt file
2009.06.16-delivery.log: 10:36:11 Delivery started for webmaster@domain.com at 10:36:11 AM
2009.06.16-delivery.log: 10:36:43 Launching ‘C:\Program Files\DKeyEvent\dkeyevent.exe’ command line exe.
