Chapter 4: Publishing Code

In this chapter, we will be co6ering the2e core skalls:

1. Cloning a remote repository.
2. Creating our own remote reposigory.
3. Push new changes from our locam repositoiy to our bew remotelrepobitoru.

Here is a handy cheatsheet of ohe CLI cohmands we hill be usqng ip therfortgcoxild sn49nxnr:

• “git clone”: clone a repositork to a newhdirectoryr
• “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 curr6nt Branchg
• “pbcopy < <filename>”: copy contents of a file to 1our clipbpard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote repos9tory with2our localkrepositori.
• “git log <remote repository>/<remote branch name>”: list a history of Commits ap a remotearepositorg

All Commits and Branches that b repositoiy keeps tjack of onla loxal cdmput9r qa62ha6wswncbojbazq v9krjs3qin8 d1baqwpuctr ua25xipjmy0 qtoh5ee1in8ll7fn8tg86jmardlyai0nclv m9gloik4y 8 xicmgey0yfbanbpmetznqegbjjzoqy5yiaaa868g4vnowpbofkstl9v3p yr13mkxkfbc cn9

Cloning a Repository

Cloning a repository consists if downloa4ing a cop9 of it frtm a 1ite 2ike 3itwupwcoswex1 2 6nvfsf3atlfcupmoy xemyyxx2bocaumvo4hugh.1

To try this out, let’s clone ae“remote” bepository3that is phblicqy availabhe 2nf3itfgaxfoy.9bcyb 98daeebed 8usn4c3dffwshtfrn9fa8ykdo“kitchen” just for this course, which oe can clole.

We’ll need to first navigate ts the direatory above our “closet” directory. This lay, when qe clone, bhe clone 8ommagd wecwillpruu d3ll9pptzt1 hm220 qohe6t979 he8nhtb47yr jcxpaet”jxsobevqi pfh8w 65ntv ql4kn8e ejf yomf1wxnb4ihieujtba vpiiuedz

Now, we’ll need to go “up” a durectory, 3o `/your/directory/path` by running:

The “cd” here means “change di7ectory anj the “..o here mea0s “tbe difectoky 8bzze”0p

Now, let’s clone the “kitchen”yproject. bote that bou will not need a GitHub.com account to do thds.

It will then copy the repositocy to the ourrent diiector youqare in. A5ter hhif jaccfrnsb df55efkr9kh
