Oh no, we made a bad commit! How can we undo making the commit, and go back to a point where we can try again?
|
||
|
|
|
||
|
|
The answer is using `git reset [commit]`, which does two things:
|
||
|
|
|
||
|
|
- It resets the current branch ref to the commit you specify.
|
||
|
|
- And it resets the index to that commit.
|
||
|
|
|
||
|
|
It does not change your working directory in any way, which means that after that, you can try making the commit you want again.

|
git add .

|
git commit -m "Initial commit"
|
||
|
|
echo "1 2 3 4 5 6 7 8 9 11" > numbers
|
||
|
|
git commit -am "More numberrrrrs"

# In the last main commit, the numbers file contains the numbers from 1 to 10.
|
||
|
|
test "$(git show main:numbers)" = "1 2 3 4 5 6 7 8 9 10"
|
||
|
|
# The commit message of that commit is "More numbers".
|
||
|
|
git log -1 --oneline | grep "More numbers"
|
||
|
|
# The commit with the typo is not part of the main branch anymore.
|

|

git log --oneline | grep -v "rrrrr"
