my file has around 1 lakh rows and 300 columns.
Though the command mentioned above is working fine but is taking more than 2 hrs to completely execute and is time consuming.
Is there any command that can specify only the column values and column number where we have the difference like
If there is difference at column number 3 and column number 7, resultant file will have value as
3,7 (Column Number)
Rahul,23 (Values present in file 1)
Rather than displaying "," for all the columns that are matching between two files. It only display columns where we have the mismatch but with a column number to keep the track.
Thanks

COLRM(1) BSD General Commands Manual COLRM(1)
NAME
colrm -- remove columns from a file
SYNOPSIS
colrm [start [stop]]
DESCRIPTION
The colrm utility removes selected columns from the lines of a file. A column is defined as a single character in a line. Input is read
from the standard input. Output is written to the standard output.
If only the start column is specified, columns numbered less than the start column will be written. If both start and stop columns are spec-
ified, columns numbered less than the start column or greater than the stop column will be written. Column numbering starts with one, not
zero.
Tab characters increment the column count to the next multiple of eight. Backspace characters decrement the column count by one.
ENVIRONMENT
The LANG, LC_ALL and LC_CTYPE environment variables affect the execution of colrm as described in environ(7).
EXIT STATUS
The colrm utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
awk(1), column(1), cut(1), paste(1)
HISTORY
The colrm command appeared in 3.0BSD.
