Finding the difference between files, and patching

- [Instructor] Welcome to the next video of section three,…finding the difference between files, patching.…In the previous video, we've learned how…to create ISO files in hybrid ISO.…This video illustrates how to generate differences…between files highlighted with line numbers.…When multiple versions of a file are available,…it's very useful when we can find…the differences between files being highlighted…rather than comparing two files manually.…If the files are large, it is very difficult…and time-consuming to compare them by hand.…When working on large files by multiple developers,…when one of them has made changes,…and these changes need to be shown to the other,…sending the entire source code…to other developers manually is time-consuming.…

Sending a difference file instead is very helpful,…as it consists of only lines which are changed,…or added, or removed, and line numbers are attached with it.…The difference file is called a patch file.…We can add the changes specified in the patch file…to the original source code by using the patch command.…
