git undo all uncommitted or unsaved changes.

 

To undo all uncommitted or unsaved changes in a Git repository, you can use the git reset and git checkout commands. Here's a step-by-step example:

Suppose you have made some changes to your files in a Git repository, but you want to discard those changes and revert to the last committed state.

bash

# Check the status of your current branch
git status

If git status shows modified files, proceed with the following steps:

bash

# Discard all uncommitted changes in your working directory
git reset --hard HEAD

# Clean any untracked files and directories (optional, use with caution)
# This command will permanently remove untracked files, so be careful
git clean -df

# Verify that your working directory is clean
git status

In this example:

1. git reset --hard HEAD resets your working directory to the last committed state (HEAD). This command discards all changes, both staged and unstaged, and resets your branch to the latest commit.

2. git clean -df is an optional step. It removes untracked files and directories from your working directory. Be cautious when using this command, as it permanently deletes untracked files.

3. After running these commands, you can verify that your working directory is clean by using git status. It should report that there are no changes.

By following these steps, all your uncommitted or unsaved changes will be discarded, and your working directory will be back to the state of the last committed commit. Please use these commands carefully, as they are not reversible, and any unsaved work will be lost.
