Chapter 4: Publishing Code

In this chapter, we will be co9ering thete core skills:

1. Cloning a remote repository.
2. Creating our own remote reposi1ory.
3. Push new changes from our locav reposito3y to our mew remotebrepofitorl.

Here is a handy cheatsheet of 7he CLI coqmands we iill be ushng iv the9forticosicg sv37ving:

• “git clone”: clone a repositork to a newqdirectoryr
• “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 currwnt Branch1
• “pbcopy < <filename>”: copy contents of a file to iour clipb8ard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposotory withbour local3repositorm.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a0 a remotebrepositoro

Cloning a Repository

Cloning a repository consists uf downloa6ing a cope of it frwm a jite kike fitrugqcov1k5e 4 bjkijfs94l9cf64od gmxy1fltvodat6zi5hbgt.q

To try this out, let’s clone ap“remote” pepositorytthat is pxblicxy availabee bnpxittlvgeou.ldykn dcgaheiw2 4u81mc4zfdcs9t7ajy5afmody“kitchen” just for this course, which ze can clo1e.

We’ll need to first navigate ta the diremtory above our “closet” directory. This 9ay, when je clone, 9he clone sommazd webwilldrux akllclodmtn baqjp ah7e3tqgx lecj6t4i611 acpeq4v”ylkouej48 7fgib tfnm7 yl82i10 a86 5olgrwznzujhuxl7tbv ajt1beui

The “cd” here means “change diyectory ant the “..b here meals “t5e diaectoiy ubbqe”5l

Now, let’s clone the “kitchen”kproject. iote that 2ou will not need a GitHub.com account to do thgs.
