Shell Programming and Scripting

I have a CSV file that needs to through two seperate processes (in the end there will be 2 files (Dload.unl and Tload.unl and we'll say the input file name is mass.csv). I have a processfile() function that will call the process Dload funtion. In Dload I want to read mass.csv into Dload and then do the following:

1. remove the 6th element in the array (or the last column)
2.validate the format is mm/dd/yy
3.validate that elements 0-4 are NOT NULL
4.write @line to Dload.unl seperated by pipes (with a pipe at the end of the line)

In Tload I want to read mass.csv into Tload and then do the following:
1. Add 3 columns to the file with the following information in each column:
- @output[0] = 0
-@output[1] = Today's Date (in the format 2007-11-07 00:00:00)
-@output[2] = "A"
2.write @line to Dload.unl seperated by pipes (with a pipe at the end of the line)
Thanks in advance, I really appreciate it.

Here is an example of the input file:
0,2007,A,MassLd,7,106,212,314,81,y,

0,2008,B,MassLd,8,107,213,315,82,x,

0,2009,C,MassLd,9,108,214,316,83,z,

0,2006,D,MassLd,6,109,215,317,84,u,
