AIX syslog rotation

> cat /etc/syslog.pid
this is not a reliable pid for the syslog process.
Use somthing like
   ps -ef | grep \syslogd |awk 'print $1'

/etc/syslog.pid should be reliable on AIX.  The actual logic I use in my script for this looks like this, however:
#
# This sends a HUP to syslog so it will close it's file descriptors
# and help us assure we're getting all the data.
#
function restart_syslogd {
    for syslog_pidfile in \
      /var/run/syslog.pid \
      /etc/inet/syslog.pid \
      /etc/syslog/syslog.pid \
      /etc/syslog.pid \
      /dev/null
    do  if [ -r "$syslog_pidfile" ]
        then    debug "$0: setting syslog_pidfile to '$syslog_pidfile'"
                break
        fi
    done
    cat "$syslog_pidfile" | read pid
    if [ -z "$pid" ]
    then    debug "$0: getting syslog pid from ps"
            ps -ef | grep /syslogd | grep -v grep | read user pid junk
    fi
    if [ -n "$pid" ]
    then    verbose "restarting syslogd"
            debug "syslog PID is '$pid'"
            if kill -HUP "$pid"
            then    :
            else    warn "$0: can't HUP syslog process '$pid'"
            fi
    else    warn "$0: don't know the syslog process id"
    fi
}

Im a rookie guys so you have to bear with me.
Where exactly do these scripts go?

Thanks

Doesn't matter where you place them in the filesystem.  The important thing is to call them out of cron on whatever schedule you want.  See the man pages for cron and crontab.

k, now how do i customizze this for my system?

how do you make the script delete log files that are x days old?

Thanks again

Hey, that's a whole other question ;-)

Anyway, see the man page for find.

thanks! any chance i can also squeeze out of you how you delete the previous contents of the log file as opposed to just appending to the same file?

Thanks

> filename
will clobber the previous contents.

thanks!
