Oh heck, why not - here's a slightly improved design. Run it in the background, and it will write the user defined above when it sees the exact phrase (also defined above).
It's not the pertiest, and probably not the fastest if the logs grows very quickly, but it works, and it's be easy to modify to mail, page, whatever...
Just be careful that it doesn't flood you out if it finds the same message hundreds of times...

I need to tail -f a file so I can monitor it as it is being written to. However, there is a lot of garbage in the file that I don't care about. So normally I would just pipe and grep for the string that is important to me. However, in this case, there are two things I need to grep for. I can't... (3 Replies)

rdeliver(1) General Commands Manual rdeliver(1)NAME
rdeliver - Ruby mail filter script
SYNOPSYS
rdeliver <options> [script]
DESCRIPTION
This script serves as an example of how you can use the RFilter::DeliveryAgent class to perform mail delivery. You can also use this
script as a fully functioning mail filter.
This script is a basic mail local delivery agent (DeliveryAgent) that can be used in place of procmail, maildrop, etc. in a user's .forward
or .qmail file. The user supplies a delivery script that is written in Ruby, which avoids the limitations of the crippled mini-languages
so often used in other DeliveryAgent programs.
USAGE
rdeliver is invoked from the command line using:
% rdeliver <options> [script]
The script argument is optional. If omitted the script will look for a file called .rdeliver in the home directory.
Options are:
--load-path directory
Prepend the given directory to ruby's load path.
--log filename
Log to the given filename. If no log is specified, no logging occurs.
--home directory
Specify the home directory. rdeliver will change to this directory before reading and writing any files. The home directory
defaults to the value of the HOME or LOGDIR environment variable.
DELIVERY SCRIPT
The delivery script runs in the context of a class called Deliver (in contrast, most ruby scripts run in the context of the Object class).
So any methods added with def will be added to the Deliver class.
A minimal delivery script would be:
def main
agent.save('inbox')
end
This code defines a Deliver#main method that saves the mail into an mbox style mailbox.
The only API the Deliver script has is the #agent method. This retrieves the RFilter::DeliveryAgent object associated with the current
message. Using the API of the RFilter::DeliveryAgent object, you can access and modify the message body and headers, defer or reject the
message delivery, and deliver into various mailbox formats.
See also RFilter::DeliveryAgent and Deliver.
INSTALLATION
Assuming you have the RubyMail mail classes installed, you typically have to put something like this in your .forward file:
|"/usr/bin/rdeliver --log /home/you/.rlog"
This will call rdeliver for each new message you get, and log to /home/you/.rlog.
CATASTROPHIC ERRORS
The rdeliver script is very careful with errors. If there is any problem, it logs the error to the log file you specify. But if you do
not specify a log file, or the error occurs before the log file is opened, a record of the error is placed in a file called CATASTROPH-
IC_DELIVERY_FAILURE in the home directory. If that fails, the error information is printed to the standard output in the hopes that it
will be part of a bounce message. In all cases, the exit code 75 is returned, which tells the MTA to re-try the delivery again.
