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.

As stated this sounds like a homework assignment, in which case I doubt anyone will help you out. However if you are having trouble with a written script, post the script and what it's not doing and the desired output and we can help you figure out what's wrong and possibly even offer suggestions to make it more efficient.
