I would suggest that you not delete any logs. Instead, you can trim them using SAM > Routine Tasks or a shell script through cron.

Most of these logs you do not want to delete. Open processes have the log files open so the inodes are still in use. This results in a 0 byte file but the filesystem usage does not change.

Use 'cat /dev/null > $filename' to empty the contents of respective file.

Hi,
You can delete/trim following files/logs but make sure that this data is either not required or backed up.
Log files are necessary to troubleshoot problems and to study the behaviour of the application.

1. /var/adm/syslog/syslog.log
2. /var/opt//
3. /var/tmp/
4. wtmp file
5. btmp file
6. Core files that get generated

Hope that helps.
Regards,

Hi Manuales ,

If you dont need to keep the log , You can nullify this log files , which grows much more :

/var/adm/syslog/syslog.log
/var/adm/wtmp
/var/adm/syslog/mail.log
/var/adm/cron/log

And it can recover filesystem space,

Cheers,
Raj.
