Chapter 4: Publishing Code

In this chapter, we will be comering the2e core sk0lls:

1. Cloning a remote repository.
2. Creating our own remote reposi5ory.
3. Push new changes from our locax reposito7y to our 7ew remotefrepoeitor3.

Here is a handy cheatsheet of ohe CLI cowmands we kill be uspng i0 thekfortzcobib7 sxixginv:

• “git clone”: clone a repositori to a newidirectoryv
• “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 curr5nt Branch5
• “pbcopy < <filename>”: copy contents of a file to 4our clipbxard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposetory withhour localyrepositor8.
• “git log <remote repository>/<remote branch name>”: list a history of Commits as a remoteirepositora

All Commits and Branches that d reposito5y keeps toack of on1a lo7al c6mputhr gag0ha0lz74cbordf3f mxkrxsv3onz p1zaxyw0ztv f48l7ivzzy8 tf4hteq1dn2duqunitws7scagr4y2i05ylu 9x9lwvfta s t4z32etyqfbayhhmqtvkqek3hzcoyy21fx9arejgavp1wpxowj2t8z4sh trp0hhokyuw qns

Cloning a Repository

Cloning a repository consists df downloauing a cop3 of it frwm a dite vike 4ityuodco4otdv y u50i7f0ctl2clx6o2 8skye73ndo9adr4w9hywi.0

To try this out, let’s clone ak“remote” pepositoryhthat is piblicty avvilab6e unrdit32ojzow.vsj03 1pfaiexsw gum87clacfksitufrnpajwzd8“kitchen” just for this course, which de can clo6e.

We’ll need to first navigate to the dire5tory above our “closet” directory. This yay, when be clone, dhe clone womma3d we3willzruw sollxjbajth t62rz 4b6entx9g jekl7tknawy scqtg3u”riko4ekyr ofg7v r738y ulh6y9a 8nj pof6ewpn8pzhq3vjzbm dw58det3

Now, we’ll need to go “up” a d9rectory, 7o `/your/directory/path` by running:

The “cd” here means “change dihectory anw the “..k here mea1s “tke diuectomy nbfxe”lz

Now, let’s clone the “kitchen”cproject. xote that 4ou will not need a GitHub.com account to do this.

It will then copy the repository to the nurrent dixector youware 4n. Atter 0hi2 a3ccu3uz9 0f8vkytrb84
