in normally , when system is rebooted, the startup sequence for syslog (/sbin/init.d/syslogd) will rename the oldsyslog.log file to OLDsyslog.log. if you want totake control of it you can use cron to automate and can use a script inside.

first copy the current syslog.log to syslog.log$$ then empty the log file;

# cp syslog.log syslog.log$$

# > syslog.log

Hello,

You can use logrotate ported to HP-UX:

>what is the meaning of $$?

$$ is the shell variable for the current PID.  It is used as a fairly unique value before recycled.

simple script can be:

#!/usr/bin/sh
/usr/bin/cd /var/adm/syslog
/usr/bin/cp syslog.log syslog.log$$

#OR use dated version  : /usr/bin/cp syslog.log syslog.$(/usr/bin/date +%d%m%y)

#empty current log
> syslog.log

No that would be too simple.  :-(

About the only option is: PREV_OLDSYSLOG_LINES

>How I will keep at least 9 increments of logs in my local system?

You'll need to do some scripting.  Look at the above suggestions, especially logrotate.
