The command "git update-index --skip-worktree ${path-to-modified_file}" is used in Git to mark a file as "skip-worktree".

When a file is marked with the "skip-worktree" attribute, Git will ignore any local modifications made to that file. This means that the file will be maintained as it is in the repository, and any changes made locally will not be tracked or committed.

Here is an explanation of the elements in the command:

• "git": The command-line interface for Git version control.
• "update-index": This subcommand is used to manipulate the index file. The index file, also known as the staging area or cache, is a staging area where changes are prepared before committing them to the repository.
• "--skip-worktree": An option used with the "update-index" command to mark a file as "skip-worktree". It instructs Git to ignore any local modifications to the specified file.
• "${path-to-modified_file}": The placeholder for the path to the modified file, which needs to be specified with the actual path. This is the file that will be marked as "skip-worktree".

After executing this command, Git will not consider any local changes made to the specified file. It will remain in the same state as it is in the repository until the "skip-worktree" attribute is removed.
