I’ve had to revert my Git commits a number of times and to revert git revision involves executing a few commands in a terminal window. To save me time googling for the solution I’ll add it in here for my future reference. To revert your Git repository to a specific revision number you need to do the following:
# reset the index to the desired tree
git reset 56e05fced
# move the branch pointer back to the previous HEAD
git reset --soft HEAD@{1}
git commit -m "Revert to 56e05fced"
# Update working copy to reflect the new commit
git reset --hard
