How to count differences between two files on linux?
- by Zsolt Botykai
Hi all,
I need to work with large files and must find differences between two. And I don't need the different bits, but the number of differences.
For the differ rows I come up with
diff --suppress-common-lines --speed-large-files -y File1 File2 | wc -l
And it works, but is there a better way to do it?
And how to count the exact number of differences (with standard tools like bash, diff, awk, sed some old version of perl)?
Thanks in advance
