[git] Find commit by hash SHA in Git

I need to find a commit in Git by a given hash, SHA. For example, if I have the "a2c25061" hash, and I need to get the author and the committer of this commit.

What is the command to get that?

Just use the following command

git show a2c25061

or (the exact equivalent):

git log -p -1 a2c25061

git log -1 --format="%an %ae%n%cn %ce" a2c25061

The Pretty Formats section of the git show documentation contains

• format:<string>

The format:<string> format allows you to specify which information you want to show. It works a little bit like printf format, with the notable exception that you get a newline with %n instead of \n …

The placeholders are:

• %an: author name
• %ae: author email
• %cn: committer name
• %ce: committer email

There are two ways to do this.

1. providing the SHA of the commit you want to see to git log

git log -p a2c25061

Where -p is short for patch

2. use git show

git show a2c25061

The output for both commands will be:

• the commit
• the author
• the date
• the commit message
• the patch information
