git reset

Undo commits or unstage changes, by resetting the current Git HEAD to the specified state. If a path is passed, it works as "unstage"; if a commit hash or branch is passed, it works as "uncommit". More information: https://git-scm.com/docs/git-reset.

• Unstage everything:
  git reset
• Unstage specific file(s):
  git reset {{path/to/file1 path/to/file2 ...}}
• Interactively unstage portions of a file:
  git reset --patch {{path/to/file}}
• Undo the last commit, keeping its changes (and any further uncommitted changes) in the filesystem:
  git reset HEAD~
• Undo the last two commits, adding their changes to the index, i.e. staged for commit:
  git reset --soft HEAD~2
• Discard any uncommitted changes, staged or not (for only unstaged changes, use git checkout):
  git reset --hard
• Reset the repository to a given commit, discarding committed, staged and uncommitted changes since then:
  git reset --hard {{commit}}
