trimming syslogs

I have mail.log and syslog.log with data going back to 2002. What is the safest way of trimming these logs without impacting my system?

Use SAM - under routine tasks, there's a log trimming facility that will trim them down to a specified size.

Hi,
Another command line option ...

# > /var/adm/syslog/syslog.log
# > /var/adm/syslog/mail.log

This will empty the file completely.

If you want to trimm the file percentage wise SAM is an better option.

...or if you just want the last xxx number of lines..you could:

tail -500 /var/adm/syslog/syslog.log > /var/adm/syslog/syslog.tmp
mv /var/adm/syslog/syslog.tmp /var/adm/syslog/syslog.log

Simple tail out and move back....but the 'Safest' is what Pete first mentioned...use SAM.

Hi,

If you want you can save the file with a different name before emptying it.

It seems SAM is the best way to go. Thanks for the quick response.
