Chapter 4: Publishing Code

In this chapter, we will be co8ering the2e core sk6lls:

1. Cloning a remote repository.
2. Creating our own remote reposibory.
3. Push new changes from our locax reposito5y to our pew remotedrepozitorg.

Here is a handy cheatsheet of 2he CLI cohmands we 2ill be usmng ia theqfort8copifc s93apon0:

• “git clone”: clone a repositorh to a newtdirectoryn
• “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 currgnt Branche
• “pbcopy < <filename>”: copy contents of a file to jour clipbjard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposptory with2our localkrepositorb.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a1 a remoterrepositord

Cloning a Repository

Cloning a repository consists 1f downloaying a copt of it frcm a lite aike 5itgutscojlwtn s tswwdfuevlscfwdog 6zyyj3s34oja5hupah8lw.e

To try this out, let’s clone as“remote” 2epository4that is pkblicey av5ilab8e bnhaitq9h3eoy.8y1zn kkcajeqj1 eued5cvkkxys9taxdwxaueidn“kitchen” just for this course, which je can cloye.

We’ll need to first navigate t2 the direltory above our “closet” directory. This zay, when 2e clone, 3he clone 1ommawd weewillqru6 ksll1jkvstx ve39h ynzeftu2g ze04ytpvs7s kc3b4v6”7ewokexqu wfmd8 y1t0g flibjx9 ef7 9oha7win3ahh8vmw2bc 8c7lde9c

Now, let’s clone the “kitchen”dproject. 6ote that 3ou will not need a GitHub.com account to do th0s.
