How to fall back to a certain version of git history

Falling back to history in Git is called a "reset" and includes the following steps: 1. Check the history to find the commit hash value; 2. Use the git reset command to reset the HEAD pointer to a specific commit; 3. (Optional) Use the --hard flag to reset the work tree to discard uncommitted changes. Note: Resetting HEAD is reversible, while resetting the working tree is irreversible.

How to fall back to a certain version of history in Git

The process of falling back to a version of history in Git is called a "reset". It allows you to move the current working tree and HEAD pointer to a specific commit point in the history.

step:

1. Check the history

Use the git log command to view the project's submission history. Find the hash value of the commit you want to fallback to.

2. Reset the HEAD pointer

Use the git reset command to reset the HEAD pointer to a specific commit:

 <code>git reset </code>

This resets the HEAD pointer, but does not modify the work tree.

3. Modify the work tree (optional)

If you want to fall back to the work tree to the corresponding commit state, use the --hard flag:

 <code>git reset --hard </code>

This will discard all uncommitted changes in the current work tree and reset them to the specified commit state.

Notice:

• Resetting the HEAD pointer is reversible and you can use the git reflog command to view history.
• Resetting the work tree is irreversible, so make sure you have backed up any important uncommitted changes before executing.
• If you are working in a collaborative project, please notify the team before resetting, as this may affect changes from other users.
