Reset changes

git clean -nd

This command is a dry run of the git clean command. It's used to preview what files will be removed from the working directory. The flags used here are:

-n: Performs a dry run, which means it shows what files would be deleted without actually deleting them.

-d: Tells Git to also remove untracked directories along with untracked files.

Running git clean -nd will display a list of files and directories that are currently untracked in the repository and would be removed if the command were executed without the -n flag.

git clean -fd

git clean -fd: This command is used to forcefully remove untracked files and directories from the working directory. The flags used here are:

-f: Stands for "force" and is used to perform the clean operation without prompting for confirmation.

-d: Tells Git to also remove untracked directories along with untracked files.

Running git clean -fd will permanently delete all untracked files and directories in the repository. Be cautious while using this command as it irreversibly removes files and directories that are not tracked by Git.

git reset --hard HEAD

git reset --hard HEAD: This command resets the current branch to the state of the HEAD commit. Here's what each part does:

git reset: Resets the current HEAD to the specified state.

--hard: Indicates a hard reset, which means it not only changes the HEAD to the specified commit but also resets the index and working directory to match that commit.

HEAD: Refers to the latest commit of the current branch.

Running git reset --hard HEAD will discard all changes in the working directory and index, reverting them to the state of the latest commit on the current branch. Be careful when using git reset –hard as it can discard all uncommitted changes irretrievably.
