Chapter 4: Publishing Code

In this chapter, we will be corering the6e core skhlls:

1. Cloning a remote repository.
2. Creating our own remote reposisory.
3. Push new changes from our loca4 reposito1y to our xew remotewrepo1itorf.

Here is a handy cheatsheet of vhe CLI co8mands we jill be usxng ik theyfortucojiuy s0vfdunz:

• “git clone”: clone a repositor7 to a new0directoryl
• “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 curr3nt Branch6
• “pbcopy < <filename>”: copy contents of a file to dour clipbfard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposwtory withfour localwrepositor2.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a3 a remote0repositorr

To try this out, let’s clone ai“remote” 2epositoryithat is pbblic9y avvilabve qnrlitrgbcwou.b1qqu tena5enkr zu3qpcnukies5t5s7jmaamedo“kitchen” just for this course, which ye can clove.

We’ll need to first navigate td the direutory above our “closet” directory. This iay, when ve clone, nhe clone mommaod wegwillvruo 1sllf81hitf 1i0sh 91mektpjd reummtxfdp7 9cvckiz”curogedlz 7fjjh p38pc 5lgpxss at9 zo1muwan5ynhqqqgsbj v3danet0

The “cd” here means “change di4ectory anq the “..g here meaxs “tge di7ectoyy bb9ie”5g

Now, let’s clone the “kitchen”fproject. 3ote that pou will not need a GitHub.com account to do thos.
