How do I reset the working tree without moving HEAD?
git
Solution
`git checkout [-p|--patch] [<tree-ish>] [--] <pathspec>...`
`git checkout with <paths>` or `--patch` is used to restore modified or deleted paths to their original contents from the index or replace paths with the contents from a named `<tree-ish>` (most often a commit-ish).
So you need to run this at root of your repository (works fine for any sub-tree or file(s) too):
git checkout HEAD~ -- .
This will result in git applying changes necessary to revert files to `HEAD~` state not counting file removals, the changes will be in the index. Add `--no-overlay` flag to allow removal of files added since `HEAD~`:
git checkout --no-overlay HEAD~ -- .
From `man git-checkout` (git v2.44.0):
`--overlay`, `--no-overlay` In the default overlay mode, `git checkout` never removes files from the index or the working tree. When specifying `--no-overlay`, files that appear in the index and working tree, but not in `<tree-ish>` are removed, to make them match `<tree-ish>` exactly.
Problem
Given a git branch with some commits on it (C is the most recent commit): ``` A -> B -> C ``` How do I reset my workspace so that all the files are in the state they were at commit B, but HEAD is still at C? I've looked at `git-reset`, but none of the options seem to help. The man page suggests that all the different modes will move HEAD: ``` --soft Does not touch the index file or the working tree at all (but resets the head to <commit>, just like all modes do). ``` I've tried `git reset HEAD~` but that moves HEAD.
