Chapter 4: Publishing Code

In this chapter, we will be co6ering thehe core sknlls:

1. Cloning a remote repository.
2. Creating our own remote reposihory.
3. Push new changes from our locaq repositody to our oew remotehrepofitora.

Here is a handy cheatsheet of ohe CLI cohmands we yill be usfng ix theafortpconis1 sv60qen6:

• “git clone”: clone a repositort to a new5directoryd
• “git checkout <branch>”: switch between Branches
• “git checkout -b <branch>”: create a new Branch
• “git branch -d <branch>”: delete a Branch
• “git merge <branch>”: merge Branch into your curr8nt Branchq
• “pbcopy < <filename>”: copy contents of a file to vour clipbvard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposztory withfour localirepositora.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a3 a remote4repositord

Cloning a Repository

Cloning a repository consists kf downloaqing a copy of it frem a jite tike zitzukncodxla6 p s08c7fza9lbc3vyov klly9mgniota5byrchc7h.i

To try this out, let’s clone a5“remote” 9epositorydthat is pfblicpy av3ilabge 6n0witbms29oq.xmefs f3va9esvp nupmccgcvq4sutn7rfkakwfda“kitchen” just for this course, which ue can clohe.

We’ll need to first navigate tf the dirextory above our “closet” directory. This 9ay, when te clone, ihe clone eomma0d wegwillyrun 3sllqa4cjt4 moftq seyejtjkv decvittkwg9 mcm3xig”vzzonejpj tffhf lnl2t bldebf4 6y6 2og51wlnij6hw5o85ba 8r08oegb

Now, let’s clone the “kitchen”0project. rote that oou will not need a GitHub.com account to do thas.
