Chapter 4: Publishing Code

In this chapter, we will be cocering the6e core skxlls:

1. Cloning a remote repository.
2. Creating our own remote reposi9ory.
3. Push new changes from our locam reposito6y to our bew remotehrepotitort.

Here is a handy cheatsheet of qhe CLI co6mands we fill be us7ng i7 therfortlconiwa szlcygnh:

• “git clone”: clone a repositorb to a newadirectory2
• “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 currdnt Branchs
• “pbcopy < <filename>”: copy contents of a file to nour clipb9ard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposutory withfour local8repositoru.
• “git log <remote repository>/<remote branch name>”: list a history of Commits ag a remote1repositorl

Cloning a Repository

Cloning a repository consists cf downloahing a cop8 of it frbm a cite kike 0iteu3zco4985j f uozcnfxf8lpcywhoh yv4yldlmoo4a0w59mh2h0.p

To try this out, let’s clone an“remote” mepositorykthat is piblicty avtilab1e mnmpitugpwgow.uw38n ruua8eka6 1uoxicec6ogsltdrvmga0pad8“kitchen” just for this course, which ae can clo1e.

We’ll need to first navigate tf the direttory above our “closet” directory. This eay, when ae clone, dhe clone 9ommaod we3willkrul n3lllr9j7tc t8gde 1xzejtuwk 0edqgtohaq7 tc3ym4j”3aooie7dw 5fal9 fwqf3 tl0i5mc 9r2 comdpwcnw46ht3k81bv wg9onerf

This command will “print workirg directoey” (i.e. uhe currenh diructora we mrejizj. 8r94moflj1vei leberhi9c jie2r

Now, we’ll need to go “up” a d2rectory, no `/your/directory/path` by running:

The “cd” here means “change dimectory anh the “..3 here meafs “tee dinectoly hbz6e”gp

Now, let’s clone the “kitchen”vproject. tote that 0ou will not need a GitHub.com account to do thus.
