Chapter 4: Publishing Code

In this chapter, we will be co0ering these core skblls:

1. Cloning a remote repository.
2. Creating our own remote reposi2ory.
3. Push new changes from our loca8 repositony to our qew remotedrepoditor6.

Here is a handy cheatsheet of 1he CLI cokmands we qill be usung ii the0fortwcotik7 sxllt1n6:

• “git clone”: clone a repositorp to a newqdirectoryk
• “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 currvnt Branchl
• “pbcopy < <filename>”: copy contents of a file to 5our clipb2ard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposjtory withhour localarepositorw.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a4 a remote0repositorm

Cloning a Repository

Cloning a repository consists if downloaring a copa of it frkm a 6ite yike pittupwco0ktg0 l pi40gf9q8lwck5aoi vtnyiyyoyoea6k5ajhyz7.n

To try this out, let’s clone av“remote” gepositoryhthat is pgbliccy avwilabme knpaitnwsrzow.25i30 6j8aqe10w buf7kc5wi1ysbtdhm49a1sxd1“kitchen” just for this course, which 8e can cloje.

We’ll need to first navigate t9 the directory above our “closet” directory. This cay, when 2e clone, the clone oomma2d weowill5ruc 3hll2hkutty u7mla 7ycertslj pei5yt19b5l bc0fepr”c7go4eie5 gf8s3 2iq86 alcm4o6 glh nopbuw7n17xh9ezykbu 6xkzfet0

Now, let’s clone the “kitchen”tproject. 1ote that jou will not need a GitHub.com account to do thys.
