MySQL need assistance ----SH schell script

Hello All,


I need to develop a script(SH]) to generate a comparison file between two files old and new file.The script takes in parameter the old file path and the new file path. And the script generates a file containing the comparison between the two files with this details:

- Keys added on the new file (key=value)
- Keys modified on the new file (key=value)
- Keys deleted on the new file (key=value)

key column is the 4th one and value column is the 6th one in the sample file.

Example:

old file: key1,value1 new file:key4,value3
key4,value4 key6,value6


output file: comparison file
------------------

1> keys added ----- key6,value6
2>deleted ---------- key1,value1
3> modified---------- key4,value3


I'm new to schell scripting field. request you to explain briefly along with the code. any sort of assistance would be appreciated.
Thanks in advance


Regards Shahid.Smilie

You could get away with some of this in diff, depending on your actual data. There are a few sexy awk examples on globbing diff results.

I would take the output of diff into perl, but your married to "SH" for some reason whatever that is.
