These 3 commands that can change/rollback/revert/update a file in your git repository. Whatever you call it.
This post note their differences and their usage.
Firstly, the usage is usually
git checkout/revert/reset myfile
Checkout
- Use this to checkout a branch or specific commit
- This will rollback any changes you have in your working copy
- This will NOT make any changes to the history
Revert
- Use this to rollback changes you have committed
- This adds a NEW commit, hence changes the history
Reset
- Use this to rollback changes made to the index (eg from
git add), which will NOT change the history - Use this to change what commit a head is pointing to, which will change the history
