Example:

Search String = AWX_38900
file name=service.log

I want to search for the string 'AWX_38900' in the last line of the file service.log and if it finds a match, it has to send an email to the group of people and continue monitoring the service.log for the next message.

Someone with over 100 posts who has been in the forums for more than seven years doesn't really count as a rookie...

Great. So, take the code I suggested for doing what you're trying to do, replace the echo command with a command to invoke your mail sending utility (with an appropriate subject line, destination address, and a message body including the line you captured.

You still haven't told us what operating system you're using so there's no way we can guess at what mail sending utilities might be available to you. But with over 100 posts to your credit, you should be able to come close to solving any remaining issues on your own. See what you can do and show us where you get stuck if you can't get it to work.

logadm.conf

logadm.conf(4)							   File Formats 						    logadm.conf(4)

NAME

       logadm.conf - configuration file for logadm command

SYNOPSIS

       /etc/logadm.conf

DESCRIPTION

       /etc/logadm.conf  is  the default configuration file for the log management tool logadm(1M). Comments are allowed using the pound character
       (#) and extend to the end of line. Each non-comment line has the form:

       logname options

       where logname is the name of the entry and options are the default command line options for the logadm command. The name of the	entry  may
       be  the	same  as  the  name of the log file, or a log file name may be given in the options section of the entry. Long lines may be folded
       using a backslash followed by a newline to continue an entry on the next line. Single or double quotes may be used  to  protect	spaces	or
       alternate-style quotes in strings.

       The  preferred  method  for  changing  /etc/logadm.conf	is to use the -V, -w, and -r options to the logadm(1M) command, which allow you to
       lookup an entry, write an entry, or remove an entry from /etc/logadm.conf.

       A full description of how and when /etc/logadm.conf is used and sample entries are found in logadm(1M).
