= How to undo major coding error =
# File has been deleted, but only on the “working tree”; they haven’t been committed yet 
# Undo the changes using the checkout command with the -f flag to force overwriting the current changes:
git add .
git checkout -f

= Console commands =
git remote -v               = list all remotes of github repo
git add .                   = add all files to github staging area
git commit -m "[message]"   = commit local repo changes with [message]

/*** if branch exists on local but not github ***/
git push -u [repo] [branch] = map local branch to [repo][branch] & push local repo commits (local & repo branches must have same name)

/*** if branch doesn't exist on github or local ***/
git push [repo] [local branch]:[remote branch]  = create [github] branch (if non-existent)/connect local branch to [github] branch
                              = example: git push origin master:feature/carrierwave, then you must checkout to that branch 

/*** if branch exists on github but not local ***/
git checkout -b [name] [repo][branch] = on local, create non-existent branch [name] & track [repo][branch]
                                      = example: git checkout -b fix/db origin/fix/db

/*** reaname branch locally & remotely ***/
git branch -m old_branch new_branch         # Rename branch locally    
git push origin :old_branch                 # Delete the old branch    
git push --set-upstream origin new_branch   # Push the new branch, set local branch to track the new remote

git fetch origin            = fetch origin & pull all branches
git checkout [name]         = checkout to existent branch        
git branch -v               = list all local branches & most current commit
git branch -a               = list all branches on local & remote
git branch -d [name]        = delete branch [name] (must not be on that branch)

git checkout -- [filename]  = revert changes on [filename] on local repo
git reset --hard HEAD       = rever 1 commit on all files & unstage changes
git reset HEAD [filename]   = revert 1 commit on [filename]
git stash                   = save (stash) changes for later (but not commit) then revert code back prior to stash
git status -s               = git status short format
git status -s | sed 's/?? //' | xargs rm -r = revert all changes on local repo (master nuke)
git log --oneline           = show oneline log of commits
git diff [branch1]...[branch2] = compare differences between branch1 and branch2
                               = example: git diff --staged
