# show commit tree (possibly append --all for all branches)
git log --graph --oneline --decorate
# save previous as an alias and then just use 'git tree'
git config --global alias.tree "log --graph --oneline --decorate"

# restoring lost commit (e.g. after git reset --hard HEAD~1)
git fsck --lost-found
# or
git reflog
git merge <hash>

# delete branch (remote and local)
git push origin --delete <branch_name>
git branch -d <branch_name>
# if branch has unmerged commits, force delete with '-D'
