Is this a homework assignment? Homework assignments must be posted in the Homework & Coursework Forum and must include a completely filled out homework & coursework template.

When asking questions in these forums, it is always a good idea to tell us what operating system and shell you are using.

For questions concerning the handling of dates and times, it is crucial. Date processing on some systems is MUCH simpler than it is on some other systems. What operating system are you using?

What shell are you using? (And, if it is a Korn shell (ksh), what version is it?)

And, if you can't give us an example of what output you're trying to produce from your sample input (and a specific date and time at which the script is run), I don' see how we can help.

I have never seen a script that would be able to send an e-mail message to someone and force the recipient of that e-mail to send that message to a physical printer. I'm guessing that that isn't really what you mean, but that is what your description requires.

There are LOTS of things missing from these requirements that make creating a script for this impossible:
  1. What date applies to lines that don't have dates on them? Is it the current date? Is it the date specified on the first line before it that contains a date? Is it the date specified on the first line after it that contains a date?
  2. What year is associated with dates in column 2? Is it the current year if the date on that line is less than or equal to the current date and the previous year if the date on that line is greater than the current date? Is it always in the current year?
  3. In the requirement: "Now I need a script to add column 2nd and column 3rd entries and compare it with current time( HH:MM format) and if it exceeds more than 15 min then I should get all such column A entries printed in email body.", what does all such column A entries mean? All lines that contain the string contained in column 1? All lines that contain the string contained in column 1 in column 1? Just print column 1 from lines where column 2 + column 3 + 15 minutes is earlier in the day than the current time in the current day? Please give us a clear specification of what you are trying to do!
There are other ambiguities in your requirements. Please write clear requirements and show us examples (in CODE tags) that highlight how those requirements affect the output you're trying to produce.

test::script

Test::Script(3) 					User Contributed Perl Documentation					   Test::Script(3)

NAME

       Test::Script - Basic cross-platform tests for scripts

DESCRIPTION

       The intent of this module is to provide a series of basic tests for 80% of the testing you will need to do for scripts in the script (or
       bin as is also commonly used) paths of your Perl distribution.

       Further, it aims to provide this functionality with perfect platform-compatibility, and in a way that is as unobtrusive as possible.

       That is, if the program works on a platform, then Test::Script should always work on that platform as well. Anything less than 100% is
       considered unacceptable.

       In doing so, it is hoped that Test::Script can become a module that you can safely make a dependency of all your modules, without risking
       that your module won't on some platform because of the dependency.

       Where a clash exists between wanting more functionality and maintaining platform safety, this module will err on the side of platform
       safety.

FUNCTIONS

   script_compiles
	   script_compiles( 'script/foo.pl', 'Main script compiles' );

       The "script_compiles" test calls the script with "perl -c script.pl", and checks that it returns without error.

       The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the
       local name used will be shown in the diagnostic output.

       Note also that the test will be run with the same perl interpreter that is running the test script (and not with the default system perl).
       This will also be shown in the diagnostic output on failure.

   script_runs
	   script_runs( 'script/foo.pl', 'Main script runs' );

       The "script_runs" test executes the script with "perl script.pl" and checks that it returns success.

       The path it should be passed is a relative unix-format script name. This will be localised when running "perl -c" and if the test fails the
       local name used will be shown in the diagnostic output.

       The test will be run with the same perl interpreter that is running the test script (and not with the default system perl). This will also
       be shown in the diagnostic output on failure.
