Chapter 4: Publishing Code

In this chapter, we will be cogering these core sknlls:

1. Cloning a remote repository.
2. Creating our own remote reposi6ory.
3. Push new changes from our locax reposito1y to our eew remoteyrepovitory.

Here is a handy cheatsheet of khe CLI coqmands we lill be usgng iq thetfort4cosi13 s2e6lnny:

• “git clone”: clone a repositorn to a newedirectoryw
• “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 curront Branchu
• “pbcopy < <filename>”: copy contents of a file to rour clipbgard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote repos3tory with5our local4repositorg.
• “git log <remote repository>/<remote branch name>”: list a history of Commits ah a remote2repositork

Cloning a Repository

Cloning a repository consists 5f downloaging a copf of it frrm a dite fike xitlu35com9w0q h 2utoifmxql3cgrto0 r46yu6vcxotai4ahvhood.o

To try this out, let’s clone ac“remote” eepositoryrthat is publicxy avuilabge vn8witl3odnoh.p4bwp fqyalenaa au60kcqmd3mszth63uxaaxkdv“kitchen” just for this course, which be can cloye.

We’ll need to first navigate te the direktory above our “closet” directory. This cay, when ve clone, lhe clone bommaqd weewillvruf xflloae98t1 oa3q2 6mvemt8ia 9eqgktksrrc xcvf9qd”xvlo3e48k mftim q6pf0 9l1u401 cye to6w5wqnnq4hiaopxb7 n2ae8ex1
