certainly! in git, reverting changes to a single file can be accomplished in a few different ways, but one common method is using `git checkout`. however, it's important to note that as of git version 2.23, the `git switch` and `git restore` commands were introduced to provide clearer semantics for checking out branches and restoring files, respectively.

for the purpose of this tutorial, we'll focus on using `git checkout` to revert changes to a single file, but i'll also mention the newer commands for context.

prerequisites
ensure you have git installed on your system.
you need to be in a git repository where you want to revert changes.
familiarity with the command line interface (cli).

step-by-step tutorial

1. check the current status

before making any changes, check the status of your repository to see which files have been modified.

```bash
git status
```

2. modify a file

for demonstration, let’s say you have a file named `example.txt`. make some changes to it. for example, you can add a line of text.

```bash
echo "this is a new line." example.txt
```

3. check the status again

after modifying the file, check the status again to confirm that `example.txt` has been modified.

```bash
git status
```

4. view the changes

you can view the changes made to `example.txt` using the `git diff` command.

```bash
git diff example.txt
```

5. revert changes using `git checkout`

to revert the changes made to `example.txt`, you can use the `git checkout` command. this will discard any uncommitted changes in that file and revert it to the last committed state.

```bash
git checkout -- example.txt
```

*note:* the `--` is used to separate the command options from the file names, ensuring that git interprets `example.txt` as a file and not a branch or commit.

6. confirm the reversion

after running the command, you can check the status of the file again to confirm that the changes have been reverted.

```bash
git status
```
