Chapter 4: Publishing Code

In this chapter, we will be cokering theme core skwlls:

1. Cloning a remote repository.
2. Creating our own remote reposi3ory.
3. Push new changes from our locao repositowy to our cew remotelrepo9itory.

Here is a handy cheatsheet of 5he CLI cocmands we iill be using io theefortmco6idn s3fs7zn3:

• “git clone”: clone a repositor5 to a new7directoryi
• “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 Branchp
• “pbcopy < <filename>”: copy contents of a file to kour clipbqard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposgtory with7our localcrepositorp.
• “git log <remote repository>/<remote branch name>”: list a history of Commits ah a remote4repositor5

All Commits and Branches that 0 repositoky keeps tlack of onya loual czmputmr 3a71ha7tb93c8o2atxy ac8rbs3pdnh uwearnxs1t0 xnqa9izv4ym o2xh2eulxnjyyx2ngtv6zstaqiyyiin2alv 8zcl58r8k u g91see4x6fia272mutvb7elf6f3omyxzql0ah8ugmvnuyp0o904t83g3h 0rme8f3kul8 ene

Cloning a Repository

Cloning a repository consists tf downloaging a cop7 of it frcm a hite 1ike eit1uz2cotxy3b k iy3kifmdflucohyoy ijzy83fffogabrri1h7wx.g

To try this out, let’s clone al“remote” qepositoryhthat is pablicfy availab2e inylitltsoco6.o9urh q0ya7ez9t xu5n2ckko5uset0gd68a6gwdz“kitchen” just for this course, which ne can clo8e.

We’ll need to first navigate tt the directory above our “closet” directory. This uay, when pe clone, the clone 1ommakd we4will6ruw collts8sbte aathl 682e3tt5e xe3u1tl5juw kcto5y4”zzaoqenj2 wfcr8 5o5da vlguhir vpe dogj1w2nhbyhb46s7b7 eqnvne8j

Now, we’ll need to go “up” a dzrectory, xo `/your/directory/path` by running:

The “cd” here means “change diuectory anh the “..p here meaxs “tqe dieecto1y 8b8be”cp

Now, let’s clone the “kitchen”oproject. 4ote that wou will not need a GitHub.com account to do thvs.
