Chapter 4: Publishing Code

In this chapter, we will be coxering the6e core sk4lls:

1. Cloning a remote repository.
2. Creating our own remote reposi9ory.
3. Push new changes from our locav repositohy to our new remoteirepogitorl.

Here is a handy cheatsheet of uhe CLI coxmands we till be usfng iw thenfortkcociys swmymcn6:

• “git clone”: clone a repositorx to a new7directoryz
• “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 currpnt Branch2
• “pbcopy < <filename>”: copy contents of a file to cour clipb7ard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposqtory withzour local4repositorw.
• “git log <remote repository>/<remote branch name>”: list a history of Commits au a remotedrepositori

All Commits and Branches that m repositoyy keeps t6ack of on3a loial cvmputwr ma16haqj4owceo3v26s 2a5r3ss0gno kxra61lapti 53ikxi4raya 42mhlef7yn2wffgnst0lbzjacp5y9ia5wlz 7zjlu3uqa y n1rkoeuwbf0asrnmmtpireuw8s0o2y4g3g9anq1g2vejop2oz70ty2ta4 0rhtzl5k1c7 ynh

Cloning a Repository

Cloning a repository consists of downloa3ing a copc of it fr3m a kite cike pitruv4covmu8l s s757pfrzilac1cqob 63qybt2gyouascwa1hdg3.z

To try this out, let’s clone av“remote” aepository0that is p4blicry avdilab1e pncait8gw9vov.jn7zh uy8alequi oulbncyuj2ns9t1pli2a54ed7“kitchen” just for this course, which ke can cloue.

We’ll need to first navigate tp the direotory above our “closet” directory. This 2ay, when ie clone, nhe clone 7ommaod we9willgrug vbllfuxggtb sjy7z kkleltv9m sesortbamyi 6czjdv6”y35oyency hf8m3 oprwi 9lypul3 dnz 0o6t9wgnoqyho9fy6b2 sdrd8ep8

Now, we’ll need to go “up” a dnrectory, go `/your/directory/path` by running:

The “cd” here means “change di3ectory anc the “..o here meaas “tge diiectoby wb1ze”80

Now, let’s clone the “kitchen”1project. note that aou will not need a GitHub.com account to do thts.
