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 =============

set_color(1)							       fish							      set_color(1)

NAME
set_color - set_color - set the terminal color set_color - set the terminal color Synopsis set_color [-v --version] [-h --help] [-b --background COLOR] [COLOR] Description Change the foreground and/or background color of the terminal. COLOR is one of black, red, green, brown, yellow, blue, magenta, purple, cyan, white and normal. o -b, --background Set the background color o -c, --print-colors Prints a list of all valid color names o -h, --help Display help message and exit o -o, --bold Set bold or extra bright mode o -u, --underline Set underlined mode o -v, --version Display version and exit Calling set_color normal will set the terminal color to whatever is the default color of the terminal. Some terminals use the --bold escape sequence to switch to a brighter color set. On such terminals, set_color white will result in a grey font color, while set_color --bold white will result in a white font color. Not all terminal emulators support all these features. This is not a bug in set_color but a missing feature in the terminal emulator. set_color uses the terminfo database to look up how to change terminal colors on whatever terminal is in use. Some systems have old and incomplete terminfo databases, and may lack color information for terminals that support it. Download and install the latest version of ncurses and recompile fish against it in order to fix this issue. Version 1.23.1 Sun Jan 8 2012 set_color(1)
