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.

RCSFREEZE(1)						      General Commands Manual						      RCSFREEZE(1)

NAME
rcsfreeze - freeze a configuration of sources checked in under RCS SYNOPSIS
rcsfreeze [name] DESCRIPTION
rcsfreeze assigns a symbolic revision number to a set of RCS files that form a valid configuration. The idea is to run rcsfreeze each time a new version is checked in. A unique symbolic name (C_number, where number is increased each time rcsfreeze is run) is then assigned to the most recent revision of each RCS file of the main trunk. An optional name argument to rcsfreeze gives a symbolic name to the configuration. The unique identifier is still generated and is listed in the log file but it will not appear as part of the symbolic revision name in the actual RCS files. A log message is requested from the user for future reference. The shell script works only on all RCS files at one time. All changed files must be checked in already. Run rcsclean(1) first and see whether any sources remain in the current directory. FILES
RCS/.rcsfreeze.ver version number RCS/.rcsfreeze.log log messages, most recent first AUTHOR
Stephan v. Bechtolsheim SEE ALSO
co(1), rcs(1), rcsclean(1), rlog(1) BUGS
rcsfreeze does not check whether any sources are checked out and modified. Although both source file names and RCS file names are accepted, they are not paired as usual with RCS commands. Error checking is rudimentary. rcsfreeze is just an optional example shell script, and should not be taken too seriously. See CVS for a more complete solution. GNU RCSFREEZE(1)
