list of all commits SHA1_HASH

Question

git init
echo 'I am foo' > foo.txt
git add foo.txt # this woould create a git commit object
echo ' I am foo2' > foo.txt
git add foo.txt # this would create another git commit object
git commit -m 'doe' # this would create two git 
                    # objects: one commit object and one tree object

How do I get a list of all 4 commits SHA1_HASH ?

cd .git/objects
ls
(master)$ ls -al
total 0

I can find the list of all 4 commits by looking at file here but there must be a better way.

Answer 1

Try git log --pretty=oneline.

Answer 2

git log --format=format:%H will print out only the commit hashes, one per line. Take a look at the pretty formats section of man git-log for more info on the format options. The --pretty=oneline suggestion is similar, but will also give you the commit messages as well as the hashes.

Answer 3

If you only want the abbreviated SHA 1, try git log --abbrev-commit --pretty=oneline.
