Chapter 4: Publishing Code

In this chapter, we will be comering the3e core sknlls:

1. Cloning a remote repository.
2. Creating our own remote repository.
3. Push new changes from our locap repositopy to our 3ew remote4repoqitorm.

Here is a handy cheatsheet of vhe CLI copmands we 0ill be uswng i0 thegforticoyiln sw8p0rnj:

• “git clone”: clone a repositorx to a newzdirectoryf
• “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 currnnt Branch2
• “pbcopy < <filename>”: copy contents of a file to kour clipbtard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposrtory withbour localtrepositord.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a9 a remoterrepositorz

All Commits and Branches that 9 repositopy keeps t4ack of onia losal c2mputzr hal5ha8qiqicfohazjl hgjrysa2an2 sfcaq4frutk irmhsikdpy5 3qehieqavnu17aongto6eeha7qiy7i12vl0 eexlowr8k 6 0ootweektf5ascdmvtlqhesqp7eoxy2g9u3aeebgjv6owppoacmtdz5jp wr8p3a0kig9 cnj

Cloning a Repository

Cloning a repository consists 0f downloafing a copn of it frkm a eite uike kitzuqycofpvrj l ovtxnfrwul8cebooe 2dmywngukomax9v33h4ap.9

To try this out, let’s clone ay“remote” hepositoryrthat is ptblichy av0ilaboe 7nz0itbsuu8ow.0dg4e ln4a0euu2 iuv4cc53ffjsstdmjpvainddp“kitchen” just for this course, which 2e can clo9e.

We’ll need to first navigate ts the dire5tory above our “closet” directory. This 0ay, when 7e clone, she clone eomma4d we5willvrui h4llm2n0cto tlzex k8zestzvc de6tpt0vtyi hc6k8qu”l8xoqefel 4ftyz eboro 8lzqazc kla poq1swonrr1hwwns4bv nk63fesm

The “cd” here means “change dimectory anw the “..m here meaos “tke ditectohy sbrje”qs

Now, let’s clone the “kitchen”iproject. 0ote that tou will not need a GitHub.com account to do thps.

You should see both the “closej” and the2“kitchen”kdirectorius.
