shell script to process file line by line
Hi ,

I am new to shell scripting (ksh shell) and trying to accomplish few requiremtns.

I have a file with the following format

EMP NO EMP NAME AGE Amt Paid
12 Mark Taylor 32 32333
14 James Brown Smith 23 23232
12 Mark Taylor 32 42333
13 Lary King 56 154545
15 Stevert Clark 34 34434
14 James Smith 23 23232



The script should be able to process the lines , find the lines which are similar excepting the amt paid and merge the similar lines and add the amt paid.


The expected result after running the script should look like this

12 Mark Taylor 32 47666
14 James Brown Smith 23 46464
13 Lary King II 56 154545
15 Stevert Clark 34 34434


As you can see the employee 12 and 14 got updated amt and the redundent lines removed.


Please guide onthe same.


Thanks,
RS.

amt

amt(1)								   User Commands							    amt(1)

NAME

       amt - run abstract machine test

SYNOPSIS

       amt [-s]

DESCRIPTION

       The  amt command is for use in a Common Criteria security certified system. The command is used to verify that the low level functions nec-
       essary to enforce the object reuse requirements of the Controlled Access Protection Profile are working correctly. /usr/bin/amt is a  shell
       script  that  executes  tests specific to your system. For a 32-bit system, the tests run as a 32-bit application. For a 64-bit system, the
       tests run twice; once as a 32-bit application and once as a 64-bit application.

       amt lists test results with a pass or fail for each test it performs, unless output is suppressed with the -s option.

OPTIONS

       The following option is supported:

       -s    Suppresses output.

EXIT STATUS

       The following error values are returned:

       0     All tests passed.

       >0    Count of the number of tests that failed.

       <0    Incorrect command line argument.
