Reverting to a previous version,

• Viewing a previous version and returning

If you want to check the source of a previous commit, there are two ways.

1. Reverting to a specific commit by viewing commit messages

• git log
  1. After entering the command, use the up and down arrow keys to find the desired version commit.
  2. Copy at least the first 4 digits of the hash code after the 'commit' phrase.
• git checkout copied 4+ digit hash code
• git checkout branch-name

2. Stepping back version by version

• git checkout head ~ 1
  • Reverts to one step before the latest commit.
  • You can specify the desired number of steps by changing the '1'.

Reverting to a previous version #

Even if you want to revert permanently without the option to return, there are two methods, but revert is generally recommended.

1. Creating a new commit for the reverted version

git revert head ~ 1 혹은
git revert head 커밋해시코드

• Both checkout methods explained earlier can be applied to revert in the same way.
• When using the revert command, a new commit is created for that specific commit version, so a commit message input window will appear.

2. Deleting commits after the reverted version (Not Recommended)

git reset --hard head ~ 1 혹은
git reset --hard 커밋해시코드

• Deleting remaining added files

head #

• head ~ previous step
• head ~ 2 two commits ago
• head ~ 3 three commits ago

Can be used in this way.

+ More detailed explanation of the difference between Revert and Reset #

• git revert allows you to revert the state while preserving history.
• git reset deletes history.

Use reset if you don't need the past; use revert if you might need to keep it.

revert is more recommended.
