Git Reset#
Warning
Be very CAREFUL WITH GIT RESET. It is very powerful and very useful. It is also a DANGEROUS COMMAND if used improperly since it may cause you to lose code (or text/data/whatever). Read carefully and don’t ever rush when you are using git reset commands.
HEAD
is the commit we are currently at.
A hard reset removes all uncommited changes, which means it also removes staged changes (they are staged, not commit).
git rest --hard HEAD~1
moves HEAD
to point to the previous
commit, which has the effect of deleting the last commit.
git rest --hard
without any refs implies HEAD
in this
context, therefore, it is the same as git rest --hard HEAD
.
Again, a hard reset DESTROYS any uncommitted changes, be they stated or not.
