Git: How to get total number of +/- ( Insertions and Deletions) from a single git commit

Question

I have a single git commit and would need to get the total number of insertions and deletions.

I know "git show <SHA>" is showing about details of my commit but I am not sure how to get total number of changes only from a particular commit.

git diff --stat <SHA1> <SHA2> also does't work because I should use only a single commit.

Kindly share me if you have any information.

Answer 1

You should still be able to use git diff --stat:

git diff --stat <SHA>~ <SHA>
# or, for a global total only:
git diff --shortstat <SHA>~ <SHA>

The ~ refers to the direct parent of <SHA>. You are only using one <SHA>: the commit <SHA>, and its direct parent <SHA>~.

For example:

C:\Users\vonc\prog\git\git>git diff --stat e646ab9cf83025e1000db6ec3c1716f978b099f2~ e646ab9cf83025e1000db6ec3c1716f978b099f2

 8 files changed, 15007 insertions(+), 11721 deletions(-)

For just the total:

C:\Users\vonc\prog\git\git>git diff --shortstat e646ab9cf83025e1000db6ec3c1716f978b099f2~ e646ab9cf83025e1000db6ec3c1716f978b099f2
