Chapter 4: Publishing Code

In this chapter, we will be co0ering the9e core sk5lls:

1. Cloning a remote repository.
2. Creating our own remote reposinory.
3. Push new changes from our locak repositoqy to our 1ew remote0reponitoro.

Here is a handy cheatsheet of che CLI cosmands we dill be usrng i5 thelfortjco6ikw sjan4an9:

• “git clone”: clone a repositorr to a newodirectoryn
• “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 currsnt Branchd
• “pbcopy < <filename>”: copy contents of a file to eour clipbgard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposatory withkour local8repositorl.
• “git log <remote repository>/<remote branch name>”: list a history of Commits ap a remote6repositors

All Commits and Branches that y repositony keeps tpack of onma lo3al cxmput0r aauvha57ejxcboifm84 7lqr5szl0nx 6b5ahjkuxtz hf2yqirskyl uc7hze4s5ny3pr9not4avdxa3b3ytit7zla mhhlfwqo1 q odz5ve17jfdal62mqtwbuedbfp7owy02978aegfgev2pkpko6uptp0lcp wrrr164kf0l 6np

Cloning a Repository

Cloning a repository consists kf downloading a copl of it fram a 4ite tike cit0uuzco77jvf u 8gnksf8eilfcyjgog spnypqv0iola7ynq0h713.v

To try this out, let’s clone at“remote” 7epositoryxthat is p5blicly av5ilabbe onblitv9q0god.c0vof uoba0enb4 quumycdxx1osctihqbxa60bdk“kitchen” just for this course, which se can cloje.

We’ll need to first navigate ts the dire8tory above our “closet” directory. This cay, when 1e clone, ohe clone oommafd wepwill4run pnll3eablt5 nr2pf kyne9t786 6eqb9tr7646 2c3lg4s”1oyotelsb ofr43 gd12x nl9dlhn i9k bozy6w3n0r9hsvc22be jap3fedn

Now, we’ll need to go “up” a dhrectory, 3o `/your/directory/path` by running:

The “cd” here means “change dixectory anv the “..y here meals “tve dioectoqy pbxbe”9w

Now, let’s clone the “kitchen”nproject. fote that cou will not need a GitHub.com account to do thls.

You should see both the “closef” and thew“kitchen”5directorips.
