According to manual, the -f switch is used to write specified file to the standard logfile (most probably messages.log), instead of what i understood from your post, choosing a logfile to write to. By the way, how can i tell logger to write to my file, instead of messages.log?

You need to use incrond.

I have this plist file that watches the “WatchDirectory” in my home directory for any changes to files or added files, scripts runs, or files deleted. If a change occurs, it calls the /usr/bin/logger command which basically writes to the /var/log/system.log file. All it writes though is very vague every time, nothing specific: for example

“Jul 21 19:34:41 TonyMAC Tony[16512]: path modified”

Do you know how I can have it write more specific messages like, “a file was deleted”, a script was ran or even a simple – “the change happened in this directory” to the /var/log/system.log file Thanks in advance.

To the poster above who’s rc.local script doesn’t work – if it works when you execute rc.local yourself, then its probably because the PATH isn’t set at that point, and you’ll need to specify the full path to logger.

Hi,

I like the script very much, but I cannot figure out some parts.. :(
Could you explain what “|| : ” means at the and of three lines, please.
It must be POSIX mode, but what is it doing?

Now I know what “&&” and “II” do.

Thanks,
Ge

the following code is not writing either of the messagesto /var/log/messages.What is wrong in the code?

My file is saved at /usr/local/sbin location.example is the name of my file.

if [ -e /usr/local/sbin/example ]; then
logger File exists
else
logger File does not exist
fi

I have added the above code in /etc/rc.local file.

Thankyou in advance

If you want to log to a remote Syslog server, the logger command will not work as it logs only to the syslogd on the localhost. log4sh is a logging framework for shell scripts that *can* log to a remote Syslog server as long as netcat is installed.
