syslog.log

dan burns — Thu, 28 Dec 2000 17:13:09 GMT

Looking for a script that will save /var/adm/syslog/syslog.log every week to a new file called syslog.120800(?). I do not like just having one log and one old log...Has anyone done anything like this before?

Thanks

Dan,

#!/bin/sh

dt=`date '+%m%d%y'`
cp /var/adm/syslog/syslog.log syslog.$dt

or maybe mv, but I always prefer to copy rather than move.

You would then put an entry in your crontab to run it once a week, on the day of the week and time of the day to be run. For example, to run it on Sundays at 2am --

0 2 * * 0 filenamewithpathname > /dev/null 2>&1
HTH
Mo

Dan,

Maureens solution is good, but on reboot or when you restart syslog deamon syslog.log will move to syslog.old. If you want to have syslog.log in Maureens format you should put an entry in /sbin/init.d/syslogd

dt=`date '+%m%d%y'`

and change the line
mv /var/adm/syslog/syslog.log /var/adm/syslog/OLDsyslog.log

to

mv /var/adm/syslog/syslog.log /var/adm/syslog/syslog.$dt

Regards,
Matjaz

Hi:

After mv syslog.log file you must restart syslogd daemon.

Syslogd will keep on writing on your syslog.log moved file because dont close his file descriptor.

So send HUP signal to syslogd PID to force reconfiguration of syslogd.

kill -HUP `cat /var/run/syslog.pid`

See man syslogd

If you perform the reboot every week ( the best thing for me ...) you could create a script /sbin/init.d/copy_syslog and two links
/sbin/rc3.d/Sxxxcopy_syslog -> /sbin/init.d/copy_syslog
/sbin/rc2.d/Kxxxcopy_syslog -> /sbin/init.d/copy_syslog .

The script copy_syslog in the stop section will have:
cat /var/adm/syslog/syslog.log | grep -v bootpd | grep -v repeated > DIR/syslog.`date +%y%m%d `
