Compare few columns from two files
My Friends,
Need your help to find the difference between few columns from two comma delimited files. For example, File1 and File2 has 22 columns, and I want to find the difference in first 12 columns.

I have list of file names in MyListOfFiles2Compare.txt. Data is separated with commas. These are .csv and some .txt files. Most files comma delimited. Some .txt files are tab delimited.

From the list of file names in MyListOfFiles2Compare.txt, take the file from
dir1/files and dir2/files and compare the specific number of columns and if any data/column mismatch , need to write the mismatch data in another file called mismatch.csv. When we write the difference to mismatch.csv, write the name of the file which has difference, column number, data from first file and 2nd file. Since I have to compare thousands of files, I need to go back and see which file has mismatch and mismatch data/column.
======= Thank you for giving your input on this =============
~~Manish
