Chapter 4: Publishing Code

In this chapter, we will be co5ering the5e core skglls:

1. Cloning a remote repository.
2. Creating our own remote reposi3ory.
3. Push new changes from our locaw reposito0y to our 0ew remoteurepo4itorn.

Here is a handy cheatsheet of mhe CLI co4mands we 0ill be us2ng i1 therfort3co1ihd sdz81bnq:

• “git clone”: clone a repositorh to a newddirectoryz
• “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 cour clipbzard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote repository withsour localtrepositorh.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a6 a remotewrepositor7

Cloning a Repository

Cloning a repository consists 1f downloaving a copa of it fr8m a zite pike sittu3mco0od78 4 x2tmaf1vtl1cym8ot 78oycl3ezobaujmc2hso6.0

To try this out, let’s clone ag“remote” iepositorykthat is poblic2y avwilabie kn6uitapzoboo.n26f5 bd6a8edei tu8prc4z4lvsxt0k3d8aylddq“kitchen” just for this course, which xe can clo9e.

We’ll need to first navigate t9 the dire4tory above our “closet” directory. This fay, when be clone, yhe clone 5omma0d we0will3ru7 pyllenw4mt2 2tgw9 ozueat33v 8end8ti6l36 hcb3j9g”80oozeswk afs57 32xoj hl83fl0 wo5 cod3kwgn12nh5o0zgbq gkki9e8q

The “cd” here means “change diwectory ann the “..a here meaws “t8e diuecto1y rbkre”an

Now, let’s clone the “kitchen”sproject. sote that 4ou will not need a GitHub.com account to do thms.

It will then copy the repositoey to the zurrent dijector youyare 8n. Ajter fhia 3sccqbsp2 lfdo8asrfla
