Reduce the logfile size and logfile encapsulator

[koff]

hello!
I created a logFile template to report in a message browser ERROR messages.
Then, I created a template to monitor this logfile (on NT boxes). When this file is bigger than n bytes, I reduce its size, I saved only last 100 lines on this file.
After this automatic action, my logfile template report last ERROR msg as if new error messages while they are old messages...
What must i do to not report these old messages? I must save the last 100 lines in my log file...
Any idea ?
Thank you vry much to help me...

Hi,


Stop logging.
tail -100 logfile >> logfile.new
mv logfile.new logfile
Start logging.

Hi,

Use a tool like logrotate.

But I'm not shore where to find something like this for NT.

From a unix point of view grab a copy of cygwin from www.cygwin.com

Then stop logging

#tail -100 logfile > temp_logfile
#mv temp_logfile logfile

finally start logging
