In this guide, We will get basic understanding of various git diff
options.
We will see:

If you do only git diff
, it will show difference in files between staging and unstaged (local file).
Example, if you do changes in two files: t1, t2
And, do a git add t1
on one file only. Then, git diff
will show difference for t2 only.
# after changing files t1, t2
$ git add t1
$ git status
Changes to be committed:
(use "git reset HEAD <file>..." to unstage)
modified: t1
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
modified: t2
Now, if I run git diff
$ git diff
diff --git a/t2 b/t2
index 45b983b..7c7e506 100644
--- a/t2
+++ b/t2

It shows difference of the file which has not been staged yet.
git diff HEAD
In the above example, I had modified two files: t1, t2

I’m only getting diff on the file I did staged.
By default, git diff
returns the diff of all the files changed/added. If you want to get diff of one particular file, do this:
git diff -- t2
Lets list the commit ids in shorter format.
$ git log --oneline
e7dd2a0 (HEAD -> master, origin/master, origin/HEAD) t2
007675f t1
1a2af9c test
f997108 test
9a5a776 test
85587c6 test1
574c251 test 1
Lets get diff between two commits
$ git diff 574c251 e7dd2a0
## output
diff --git a/test1.txt b/t1
similarity index 100%
rename from test1.txt
rename to t1
diff --git a/t2 b/t2
