depth depth hard

# assume the repo was cloned with
git clone --depth=1 -b main <URL> <PATH>
 
# to update 'main' we can do
git fetch --depth=1 origin main
git reset --hard origin/main
 
# to reset the local state to a different branch than 'main'
git fetch --depth=1 origin <BRANCH>
git reset --hard FETCH_HEAD

• this same procedure can be applied to the ‘main’ branch, as well, i.e., if <BRANCH> is main
