How do I revert a modified file to its previous revision at a specific commit hash (which I determined via git log and git diff)?

To revert a modified file to its previous revision at a specific commit hash in Git, you can use the git checkout command. Here's an example:

Suppose you have a modified file named myfile.txt and you want to revert it to its previous state at a specific commit hash, let's say abcdef. Here's how you can do it:

    First, make sure you're in the root directory of your Git repository.

    Use the following command to revert the file to its previous state at the specific commit hash:

    bash

    git checkout abcdef -- myfile.txt

Replace abcdef with the actual commit hash you want to revert to and myfile.txt with the name of the file you want to revert.

After running the command, the myfile.txt will be reverted to its state at the specified commit hash. Please be aware that this action is irreversible, so make sure you're certain about the commit you're reverting to.

If you want to discard changes in multiple files and revert them to the state at a specific commit hash, you can list those files separated by spaces after the commit hash, like so:

bash

git checkout abcdef -- file1.txt file2.txt file3.txt

Remember to carefully review your changes and backups before performing actions that modify your Git history or working directory.
