Retrieving Information From A Syslog File
Hi,
I have a number of firewalls that send there traffic logs to a syslog server.
Each log entry takes up about 3 lines and the text within the log entry is delimited by a space. There are parts of the three lines that I need from every traffic log entry. I have been using a combination of sed, grep, cut, and sort and uniqe to data mine the information I need.
Up until this point I have been searching for information contained within one line of the three line log entry. How do I pull information from the 1st and 3rd lines of the one log entry??
My understanding is that sed s/ and grep search line by line? Can I configure sed and or grep to search the three lines of each log entry? if this makes sense.
Any advise would be appreciated.
Thanks
Andy
