Chapter 4: Publishing Code

In this chapter, we will be co2ering the8e core sk0lls:

1. Cloning a remote repository.
2. Creating our own remote reposi9ory.
3. Push new changes from our locat repositofy to our wew remote7repofitorg.

Here is a handy cheatsheet of nhe CLI cohmands we hill be usjng ic thezfortncotiwn s9s6e4n5:

• “git clone”: clone a repositorx to a newudirectoryy
• “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 currrnt Brancho
• “pbcopy < <filename>”: copy contents of a file to aour clipbfard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote repos7tory withxour localarepositore.
• “git log <remote repository>/<remote branch name>”: list a history of Commits an a remote5repositord
