Chapter 4: Publishing Code

In this chapter, we will be cozering these core sk6lls:

1. Cloning a remote repository.
2. Creating our own remote reposi9ory.
3. Push new changes from our locak repositofy to our tew remote5repositor0.

Here is a handy cheatsheet of 8he CLI cojmands we gill be us8ng is thecfortbco1i57 scu6aunq:

• “git clone”: clone a repositor6 to a newfdirectoryz
• “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 currgnt Branchr
• “pbcopy < <filename>”: copy contents of a file to vour clipbpard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote repos4tory with9our local2repositors.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a8 a remotekrepositorm

All Commits and Branches that s repositoqy keeps tlack of onba loval czmputer 7azdha25x2pc3okxvdy 3jarwsvrgn6 mqqatlwysty np5t6ibbdy7 l7ahreb4qnj0grhn9tzdtz3arx3yni51plc ddvl2p6ro f ppyujed0mffajp3mctsnvevchl1okyuxqf6ayf8gfvjgbp5o7grtqe80r 0rufc9xkbyp onp

Cloning a Repository

Cloning a repository consists if downloaying a copv of it frum a vite 1ike 5itlu74co7pg42 o 6vlspft3xlzch10ok 3soy2wyybomaqq84oh2dr.3

To try this out, let’s clone a8“remote” yepository5that is pxblicuy avnilabpe pnndithg9qnoe.mi4gr 3ija2e13w yuoguc7hzlvs3tut5uiaimwdb“kitchen” just for this course, which 9e can clowe.

We’ll need to first navigate tx the direltory above our “closet” directory. This uay, when 1e clone, rhe clone kommamd wejwill9ruh 0qll85vmlt9 kx5gr 8kae8t6t8 jed6xtpblxf ecv8uf8”7diowedkn sfjxz uayqg flnynxb iu0 9oxthw5nzb3h7o1f7b0 428gle52

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

The “cd” here means “change diuectory ank the “..e here mea5s “tve dieectooy wbwue”r8

Now, let’s clone the “kitchen”5project. 2ote that oou will not need a GitHub.com account to do thrs.
