To commit changes to a Git repository, you need to follow these steps:
- Add files to the staging area: Use the command git add to add specific files or git add . to add all modified files to the staging area. This prepares them for the commit.
- Check the status: Run git status command to ensure that the files you want to commit are correctly added to the staging area.
- Commit the changes: Execute git commit -m "commit message" to create a new commit with the changes. Replace "commit message" with a meaningful description of your changes.
- Push the changes: If you are working in a remote repository, use git push to send the committed changes to the remote repository. This step is essential to share your changes with others.
It is important to note that committing changes with Git helps in keeping track of the project's history and makes it easier to revert or review changes in the future.

How to ignore files in Git using .gitignore?
To ignore files in Git using .gitignore, follow these steps:
- Create or open the file named .gitignore in the root directory of your Git repository. If the file doesn't exist already, simply create a new plain text file with this name.
- Open the .gitignore file in a text editor of your choice (e.g., Notepad, Visual Studio Code, Sublime Text).
- Specify the files or directories you want to ignore by adding their paths to the .gitignore file. Each entry should be on a new line. To ignore a specific file: example.txt To ignore all files in a directory: my_directory/ To ignore files with a specific extension: *.log To ignore files in a specific directory and its subdirectories: my_directory/**
- Save the .gitignore file and close it.
- Commit the .gitignore file to your Git repository for the changes to take effect.
After performing these steps, Git will ignore the specified files, directories, or file patterns according to the rules specified in the .gitignore file.
What is the Git command to revert changes?
The Git command to revert changes depends on the type of changes you want to revert. Here are three commonly used commands:
- To revert and remove the most recent commit and discard the changes made in that commit:
1
|
git revert HEAD
|
- To revert and remove a specific commit by its commit hash:
1
|
git revert <commit-hash>
|
- To revert and remove all the commits after a specific commit, effectively removing them from the branch history:
1
|
git revert <commit-hash>..<branch-name>
|
Note that these commands create a new commit that undoes the changes made in the specified commit(s) or in the latest commit. It is a safe way to undo changes without rewriting Git history.
What is the Git command to discard local changes?
The Git command to discard local changes is:
1
|
git checkout -- <file>
|
This command will discard the changes made to a specific file and restore it to the state it was in the last commit. If you want to discard all changes made to all files in your working directory, you can use:
1
|
git checkout .
|
Be cautious when using these commands, as they will permanently discard any uncommitted changes.
