[we2aresame]

Hi, all,
A software create log daily, the log file will be copied to a new file like log.1...log.100 if the log achieve a size limit. What I need is to keep the log by monthly not by size, there are date information in each line of the the log, how can I create log file by monthly from the log files. Thanks.

First, pls don't create multiple threads.

Second, give us a sample of your log file and someone might be able to get you started.

Try something like this:

awk -F/ '
NR==1{m=$2;out="log."$2}
$2!=m{close(out);out="log."$2}
{print > out}
' OldLogFile

Hope This Help

sorry, what I wrote maybe confuse you.
in the old log file, for exampel, logfile1, there are lines like:
server1 [03/May/2003:20:55:29
server1 [03/May/2003:20:55:30
server1 [03/Jun/2003:20:55:31
server1 [03/Jun/2003:20:55:31
I want to create a 2 new log file,
in newfile.may, there should be lines
server1 [03/May/2003:20:55:29
server1 [03/May/2003:20:55:30
in newfile.Jun, there should be lines
server1 [03/Jun/2003:20:55:31
server1 [03/Jun/2003:20:55:31
Anyway, thank you very much.
