Diff & Patch: An one minute tutorial

27 Sep 2008      

Most of us working in open source projects need to generate modification on a special part of code.

After making changes we need to send it. Only the difference in the file is needed to be sent.

So how to create a difference(diff) file ? Simple .Follow these steps

**_diff X.c X.c > “diff file”_**

Here diff file may be X.c.diff. __

X.c is a c language file.**_


Now if we receive the diff file, how to join(patch) it with our orginal file? See below

patch X.c X.c.diff

Made using Jekyll, Bootstrap, Code Prettify and Font Awesome.
