how do I write to /var/log/messages?

[ToddAndMargo]

Hi All,

In a script, in Red Hat, I use a utility called "logger" to write to /var/log/messages. How do I do this in Kubuntu?

Many thanks,

Right under my nose. In Red Hat it is "/bin/logger"; in Ubuntu it is "/usr/bin/logger". If the package is missing, you can get it with

apt-get install bsdutils

you will not write to /var/log/messages that way.

afaik the default location for kubuntu is /var/log/syslog

see /etc/syslog.conf for details.

Hi

Pardon my curiosity, but why would you want to manually add anything to /var/log/messages?

Things I want a record of that are done at boot time or by crond that I want a record of. That a look at part of my CentOS's rc.local:

# If Virtual Box is not loading, it is probably due to
# a kernel change. If not loaded, re-run VB setup
if [ -n "`/etc/rc.d/init.d/vboxdrv status | grep -i "not loaded"`" ]; then
  /etc/rc.d/init.d/vboxdrv setup
  logger -p user.notice -t rc.local "running Virtual Box setup (possible kernel change)"
fi

# echo your "elevator" to the log
logger -p user.notice -t rc.local " your current elevator is: `cat /sys/block/sda/queue/scheduler`"

HTH,

I opened one term and did a "tail -f /var/log/messages" and another term and wrote to it with "logger". Works great. I am not sure what you are trying to tell me.

Do they have to be in /var/log/messages? I agree with others that I wouldn't want user-created entries in a system logfile. What I do for cron jobs is dump them to a separate logfile, like this -

# date-stamp local cron log

0 0 	* * * 	wizard 	date >> /var/log/cron-output.log

# backup stuff

#
0 0 	* * * 	 wizard 	dpkg --get-selections > /home/wizard/Documents/installed-programs.log 
0 2 	* * * 	 root 	mount -t smbfs -o username=wizard,password=xxxxxxxx //192.168.1.103/documents$ /home/wizard/wifes-pc >> /var/log/cron-output.log 2>&1
15 2 	* * 0 	 wizard 	sh /home/wizard/scripts/rsync_cleanup.sh >> /var/log/cron-output.log 2>&1
15 2 	* * 1-6 wizard 	sh /home/wizard/scripts/rsync_backup.sh >> /var/log/cron-output.log 2>&1
0 4 	* * * 	 root 	umount /home/wizard/lisa-pc >> /var/log/cron-output.log 2>&1

Hope this helps -

That's what I've done as well, and I don't have to worry about any future possible changes to system files or logging paradigms. Your own cron script saving to your own log files under their own directory in your own home account.
