I want to compare the columns of two files excluding column 2 from both the files. I tried this awk command.
[Apart from column2, if the any of the columns did not match, then that whole row of file2.txt is printed; but I have compared considering that there are only 4 columns on the whole].
Example: File1.txt
File2.txt
In actual case, I am not sure how many columns each file may contain, so this awk command I constructed is limitted.
How can I compare columnwise, excluding column 2, without knowing the total number of columns in each file?

Hello,
I have not been able to find what I'm looking for via searching the forum. I could use some help with an awk script or one-liner to solve this simple problem.
