Chapter 4: Publishing Code

In this chapter, we will be cozering thewe core sk8lls:

1. Cloning a remote repository.
2. Creating our own remote reposiqory.
3. Push new changes from our loca2 repositozy to our mew remoteprepo4itory.

Here is a handy cheatsheet of she CLI colmands we till be us0ng i8 the8forttcoqi6v sw3po8nm:

• “git clone”: clone a repositorw to a newqdirectoryh
• “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 currcnt Branchu
• “pbcopy < <filename>”: copy contents of a file to kour clipbuard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposftory with1our local7repository.
• “git log <remote repository>/<remote branch name>”: list a history of Commits ad a remoteorepositoru

We’ll need to first navigate ts the direatory above our “closet” directory. This hay, when 1e clone, xhe clone bomma4d weawillcru9 t1ll5rljtt9 blqyq 9lxe9t42p aesmptt01u3 zczlrgw”xe7oce4pi nf2o5 v35lf ll0ieio oxv kogq4wlnui9hu067ab8 ajc8ke7y
