Please help in creating script for below requirement.

I will be running 1 command and will get below entries in a text file say file44.txt
*******************************

Code:

DFDL1005 06:30 00:05
ABFL2003 10/22 01:10
CFTL1256 10/24 00:10

10/25 09:20 PM

********************************

.
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.

2.)Column 2 has entries in HH:MM and MM/DD format. I want to take above action for entries in HH:MM format and want to print list of column A entries in a separate txt file if column 2nd entry(MM/DD format) is 1 day older than current date. Rest of the entries should be discarded

Please use CODE tags when displaying sample input, sample output, and code segments (as required by forum rules).

A sample output based on above input data would help. How would I compare 06:30 00:05 to the current time?
Any attempts from your side?

We need to add column 2 and column 3rd data and compare it with current time stamp, 06:30 + 00:05 = 06:35 and if current time is 06:55 then its 20 min difference and it should be printed in email body.

I did not try as Im new to shell scripting and finding hard to create script as per requirement, so posted it here and seeking for help. Kindly help!

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: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.
