# Move the current head so that it's pointing at the old commit # Leave the index intact for redoing the commit. # HEAD@{1} gives you "the commit that HEAD pointed at before # it was moved to where it currently points at". Note that this is # different from HEAD~1, which gives you "the commit that is the # parent node of the commit that HEAD is currently pointing to." git reset --soft HEAD@{1} # commit the current tree using the commit details of the previous # HEAD commit. (Note that HEAD@{1} is pointing somewhere different from the # previous command. It's now pointing at the erroneously amended commit.) # The -C option takes the given commit and reuses the log message and # authorship information. git commit -C HEAD@{1}git reset --soft HEAD^
