awk/sed line parsing

I'm new to shell programming, but I think I learn best by following an example. I'm trying to cook up an awk/sed script, but I obviously lack the required syntax skills to achieve it. The output that I get from running my ksh script looks like this:

Quote:

CHANGED FILES:
1. foo/bar.txt
2. foo/bar1.txt

NEW FILES:
1.foo/bar1.txt

DIRECTORIES:
1. foo/

I need to search each numbered line for certain keywords. If I have no match, then simply continue with the rest of my script. If there are matches, then I want to be able to capture matched lines (to a temp file?) then report the matched lines as the command's output ('cat' temp file?) and exit my script. Appreciate any suggestions.

A bit more details of my framework:

Code:

( ksh myscript.ksh 2>&1 ) | tee -a $TEMP_LOG
            perl -ne "exit 1 if ( \
                /keyword1/ || \
                /keyword2/ || \
                /keyword3/ \
            );" $TEMP_LOG
            if [ $? -eq 1 ]
            then
                echo ""
                echo "Error while running myscript.sh!"
                EXITCODE=1
            else
                echo "Done running myscript.sh."
            fi
            rm -f $TEMP_LOG

So I basically want to be able to capture the keywords from the output of another command shown above and then error out along with reporting the lines with found keywords.

print(1)							   User Commands							  print(1)

NAME

       print - shell built-in function to output characters to the screen or window

SYNOPSIS

   ksh
       print [ -Rnprsu [n]] [arg...]

DESCRIPTION

   ksh
       The shell output mechanism. With no flags or with flag - or -, the arguments are printed on standard output as described by echo(1).

OPTIONS

       The following options are supported:

       -n	       suppresses new-line from being added to the output.

       -R

       -r	       (raw  mode) ignore the escape conventions of echo. The -R option will print all subsequent arguments and options other than
		       -n.

       -p	       causes the arguments to be written onto the pipe of the process spawned with |& instead of standard output.

       -s	       causes the arguments to be written onto the history file instead of standard output.

       -u [ n ]        flag can be used to specify a one digit file descriptor unit number n on which the output will be placed. The default is 1.

EXIT STATUS

       The following exit values are returned:

       0	Successful operation.

       >0	Output file is not open for writing.
