diff output

paulp · #1 (**permalink**) 04-13-2005

I have two CSV files and I would like to create a third CSV file containing the differences between the two.

I understand the diff command can be used to list differences between two files. My problem is that when I pipe the output into a third CSV file, the line numbers and other formatting from diff also get piped. Is there any way to pipe only the actual text?

Thanks

You might try the comm command - it may give you what you are looking for with less formating to do.

Thanks

I have looked at comm but I cant get it to produce the same output as diff as it operates line by line. I was hoping the answer may lie with diff, perhaps an option. I have also been informed of uniq, but as I understand this operates on a single file only

The following may help ...

Code:

 diff file1 file2 | grep "[<>]" | sed "s/>/\t/g;s/<//g"
