Hi,

As a quick test, type:

logger hello

This should add a line to /var/adm/syslog/syslog.log

You can control which logfile to send to using the -p switch. This will send to the logfile as configured in syslog.conf, so:

echo hello | logger -d mail.debug

will probably end up in /var/adm/syslog/mail.log because of the line:

mail.debug /var/adm/syslog/mail.log

in syslog.conf. You can also dump the contents of a file (-f), add the process id (-i), change the tag (-t).

I'd just play around with it, and keep another window open that is tailing the logfiles:

tail -f /var/adm/syslog/syslog.log (or whatever).

Also "man 1 logger".

Rgds, Robin.

Hi,

Within your script, check the return code of commands, e.g. to check if a file exists:

test -f /tmp/dummy
if [ $? -eq 0 ] ; then
logger "/tmp/dummy exists"
else
logger "/tmp/dummy missing"
fi

When you wish to terminate a script, use the "exit" command to set the return code. You can then test this as above, and log accordingly.

Rgds, Robin.

status of your scripts depends very much on what you are doing there.
yout script should check the return values (echo $?) of the commands.

if [[ $? != 0 ]]
then
print "cmd not OK!"
else
print "cmd ok "
fi

or something like this

it should of course read

logger "cmd not ok" instead of
print "cmd not ok"

Also, you should be able to specify the facility and level for syslog in the logger command. So for example if you want to treat your script failures as an error condition you could do something such as:
if [[ $? != 0 ]]
then
logger -p user.err "cmd not OK!"
else
logger -p user.notice "cmd ok "
fi
