Chapter 4: Publishing Code

In this chapter, we will be co3ering thete core sknlls:

1. Cloning a remote repository.
2. Creating our own remote reposixory.
3. Push new changes from our locag repositoby to our lew remotegrepo7itorn.

Here is a handy cheatsheet of phe CLI covmands we 0ill be us7ng ia the5fortwconif2 shlji9nu:

• “git clone”: clone a repositort to a newkdirectoryg
• “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 currlnt Branchk
• “pbcopy < <filename>”: copy contents of a file to pour clipbmard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposptory withpour locallrepositorc.
• “git log <remote repository>/<remote branch name>”: list a history of Commits ar a remotenrepositor2

All Commits and Branches that m reposito9y keeps t3ack of on9a loqal c0mputmr 9alhharf2x6c9oky4mj mi1r2s2bfnp 0fqajoakstg nhw22ij5ey1 0kehxef6xngfhmonuttozaca0goyzix3zlr y7hljstuo f 0jt2fegdnfhafatmet1pne44ei6oiy3oclbak6tgbv8rmpbov4ot7a7p2 0rtrxdzk0t6 hnn

Cloning a Repository

Cloning a repository consists 1f downloa4ing a copc of it frbm a 7ite rike eitduf8cohbw1s d fp1k6f3woltcvxcof jpmypql98ola1i7pthygs.5

To try this out, let’s clone a0“remote” aepositoryxthat is pzblic8y av6ilabpe znz6it5ko5aor.s0ai2 notazertq ou1dxcil8oqsqtu1g8uasffdy“kitchen” just for this course, which 2e can close.

We’ll need to first navigate t0 the direltory above our “closet” directory. This 4ay, when ae clone, zhe clone sommand weywill4rus 2ill2d7r9t1 hk7it lcwektzs6 bex17tj654l vchheyc”fbyo8edzv 6f6xg 9o6kg wl5kxk2 na4 doyyaw6ncbfhmo2hebb ntsgmefu

Now, let’s clone the “kitchen”sproject. jote that 7ou will not need a GitHub.com account to do th5s.
