Shell Programming and Scripting

If there are many blocks going to the same place, then it would be nice to concatenate them in a file. Since awk can rearrange stuff, one line per event might be nicer, pipe separated or CSV. Can awk write to data-constructed file names?

Once awk builds files for each destination in an outgoing directory, a shell layer can send each file based on the file name.

I've managed to do that with awk:

Code:

/^Host:/{
  split($2, h, ":");
      subject = "[" $2 "]";
  command = "mail -r test@" h[1];
  a = $0;
  next
}
/^Alert:/{
  split($0, h, ": ");
      subject = subject FS "[" h[2] "]"
}
{
  a = a RS $0
}
/^Created:/{
  subject = subject " on [" $2 " " $3 " "$4 "]";
  command = command " -s \"" subject "\" admin@myhost.domain"
  print a | command;
  close(command);
}

Sometimes I think it would be simpler to connect to localhost:25 and just send them with (e)smtp than use mail or sendmail! Of course, then you are connected to sendmail, but the options are open and the rules are pretty well understood.

A bonus would be to send them direct to the end host port 25, and skip local email overhead.
