How do I revert all local changes in Git managed project to previous state?

To revert all local changes in a Git-managed project to the previous state (i.e., discard all changes in your working directory and staging area), you can use the git reset and git checkout commands. Here's an example:

Warning: This operation will permanently discard all changes, so make sure you have backups or have committed any important changes before proceeding.

bash
# Discard all changes in the working directory and staging area
git reset --hard HEAD

# Ensure that the working directory matches the state of the last commit
git checkout .

Here's what these commands do:

  1. git reset --hard HEAD: This command resets your working directory and staging area to the state of the last commit (i.e., HEAD). It discards all local changes, both staged and unstaged, and resets your branch to the commit you were on previously. The --hard option ensures that both your working directory and staging area are reset to the specified commit.

  2. git checkout .: After resetting with git reset, there might still be untracked files left in your working directory. This command removes those untracked files and ensures that your working directory is clean.

Now, your local project should be back to the state of the last commit, and all local changes have been discarded. Be cautious when using these commands, as they can't be undone, and any uncommitted work will be lost.

Here's an example of how to use these commands:

Suppose you have a Git project with some local changes and want to revert them:

bash
# Check the status of your working directory
git status

# Make sure you have committed any important changes

# Revert all local changes to the previous state
git reset --hard HEAD
git checkout .

# Check the status again to confirm that your working directory is clean
git status

After running these commands, your working directory should be clean and match the state of the last commit.
