How to implement commit and rollback in Bitbucket?

To implement commit and rollback in Bitbucket, you can follow these steps:

Commit:

Stage Changes: Use git add to stage the changes you want to commit.
```
git add .
```
Commit Changes: Use git commit to commit the staged changes with a descriptive message.
```
git commit -m "Description of changes made"
```
Push to Bitbucket: Use git push to push your commits to the remote repository on Bitbucket.
```
git push origin branch-name
```

Rollback:

View Commit History: Use git log to view the commit history and find the commit hash of the commit you want to rollback to.
```
git log
```
Reset to Specific Commit: Use git reset to reset your local repository to a specific commit. There are two main options:
- Soft Reset (--soft): This option resets the head to the specified commit but keeps the changes in the staging area.
```
git reset --soft <commit-hash>
```
- Hard Reset (--hard): This option resets the head to the specified commit and discards all changes.
```
git reset --hard <commit-hash>
```
Force Push if Necessary: If you have already pushed the commits to Bitbucket and need to rollback the remote repository, you can use git push --force to overwrite the remote branch with your local changes.
```
git push --force origin branch-name
```

Example:
Suppose you have made several commits and want to rollback to a previous commit with the hash abc123.

View Commit History:
```
git log
```
Reset to Commit abc123:
```
git reset --hard abc123
```
Force Push to Bitbucket:
```
git push --force origin branch-name
```
