Programmer who take part in some kind of big code needs to generate patch files. Begginers do get trouble here as how to create, there is simpple command on linux diff use that as follows
Suppose u have old code in oldmake folder and new code in home/newmake. Then follow these steps.
1. cd home
2. diff -urN /home/waste/oldmake newmake > patch1
Now you might have written some new file instead of modifying any file. There is no need to worry diff is already taken care of that stuff, your patch includes those files.
How to use patch
if you want to apply patch inside /home/checkmake then go to checkmake folder
1. cd /home/checkmake
2. patch -p patch1
