Hi all,
I have an input file with no delimiter. Let us say the file is abc.txt having values for fields namely, EmpNumEnameDesigSalDept. Ofcourse the file has got several records. Every field has got a fixed start and end position.
I need to assign the fields to corresponding varibles say EmpNum, Ename, Desig, Sal and Dept. Now if Dept is more than 10 and less than 15, then I have to give the 20% increment in Salary, or if Dept is more than 15, then I have to give the 30% increment in Salary. Again, for a particular Dept I need to check if the Designation is Manger. Once a record meets the above condtions, I need to pick the fields for that record and put them all (or selective fields only) in a separate file. Then I will move to the next record and so on.
Thanks in advance for resolving the issue.
Regards,
Rin..

Sounds suspisciously like homework... if so, you are violating rule 6 of this forum. Check the rules here.

Anyways, a few pointers. To get the individual fields from the file use the cut command. Check the man page for details. You can do the math using the ksh builtins or expr if you are going to be using sh/csh. I am sorry, but I won't be getting any more specific.
