Edit Question
Title
Body
I want to find the difference between two files and then put only the differences in a third file. I saw different approaches using awk, diff and comm. Are there any more ? eg. Compare two files line by line and generate the difference in another file eg. Copy differences between two files in unix I need to know which is the fastest way of finding all the differences and listing them in a file for each of the cases below - Case 1 - file2 = file1 + extra text appended. Case 2 - file2 and file1 are different.
