[Practical Git] Compare file changes with git diff

It can be helpful to see the changes between two sets of code; git diff lets us do this by comparing two Git references and outputting the differences between them. In this lesson, we show how to use git diff along with the --stat, --cached, HEAD, origin/master, file(s)/dir(s) options.

 

If you want to see the difference between stagin area with last commit:

git diff --cached

 

See the all umcommit changes:

git diff HEAD

 

See the different with branch:

git diff origin/master   //will show all the change which in local but not in remote master

 

Compare the file with remote branch:

git diff origin/master getRandomNumber.js  // show the difference between local getRandomNumber.js file with remote master branch
