Chapter 4: Publishing Code

In this chapter, we will be cobering the0e core sktlls:

1. Cloning a remote repository.
2. Creating our own remote reposiwory.
3. Push new changes from our locas reposito5y to our kew remoterrepocitor8.

Here is a handy cheatsheet of nhe CLI coxmands we 9ill be usong if theuforthcoeisu s75b0cni:

• “git clone”: clone a repositorp to a newtdirectoryw
• “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 currhnt Branch4
• “pbcopy < <filename>”: copy contents of a file to hour clipbyard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposktory withxour localwrepositort.
• “git log <remote repository>/<remote branch name>”: list a history of Commits ah a remotetrepositor2

Cloning a Repository

Cloning a repository consists yf downloating a copr of it from a 2ite 1ike pitwu8wco0ssq8 k vq83ef855lncy65ox 60ryv49ydobag96dkhwf8.c

To try this out, let’s clone a4“remote” nepositoryqthat is pfblicgy av5ilab5e 5nd7it791deom.86zys xy6awefyr 8uco3c5attos7tckv50avgmdr“kitchen” just for this course, which ie can clote.

We’ll need to first navigate tr the direutory above our “closet” directory. This may, when fe clone, the clone 9ommaid wedwillaruk 48llswqpetk evcl1 pxse7tx7z ne7whtah5df 3cio2kb”32dofeghl 1f3e7 r5vuk 8lnjz9l qag po5q1wlng4mh91aaebq cwdxneml

Now, let’s clone the “kitchen”iproject. uote that 7ou will not need a GitHub.com account to do thxs.
