• ORIG_HEAD references the commit that HEAD previously referenced.

Recipes #

Some recipes I have to look for everytime on internet. Trying to collect them all here (with the hope of improve my memory):

Undo last commit (local) #

Commit in a wrong branch, for example (source):

git reset HEAD~
# you can edit files

git reset 'HEAD@{1}'

# alternative
git reset ORIG_HEAD
