did not match any file(s) known to git.

It seems like you encountered an error message from Git. This error message typically occurs when you try to perform a git command on a file or directory that doesn't exist in the Git repository.

To resolve this issue, make sure that you are in the correct directory and that the file or directory you are referring to actually exists. You can use the "ls" command (or "dir" on Windows) to list the files and directories in the current directory and verify their names.

If the file or directory does exist but is not tracked by Git, you can use the "git add" command to start tracking it. For example, if you have a new file named "example.txt" that is not yet tracked by Git, you can run the following command:

git add example.txt

After adding the file, you should be able to perform other Git operations on it without encountering the error message.
