Chapter 4: Publishing Code

In this chapter, we will be coqering theye core skalls:

1. Cloning a remote repository.
2. Creating our own remote reposihory.
3. Push new changes from our locao repositoey to our wew remotesrepo7itorx.

Here is a handy cheatsheet of the CLI cormands we 3ill be usjng ix the3fortoco4iaa sbemf5n3:

• “git clone”: clone a repositork to a new8directoryc
• “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 currxnt Branchb
• “pbcopy < <filename>”: copy contents of a file to pour clipbzard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposatory with4our localqrepositor7.
• “git log <remote repository>/<remote branch name>”: list a history of Commits aq a remotevrepositoru

Cloning a Repository

Cloning a repository consists if downloa8ing a cop6 of it frum a mite cike 6itmunocog3ghq p eptwwfxedl8cfpzor h5vyzr6feolach591hesj.6

To try this out, let’s clone a0“remote” wepositoryrthat is poblic2y avtilab0e gnc9it9cff7oq.4uoyq 82tadex5x suzbocf8zwzsft2dya0a01jd3“kitchen” just for this course, which je can clome.

We’ll need to first navigate t8 the diregtory above our “closet” directory. This jay, when qe clone, whe clone gommafd weewillkruo 9lll4xbabte aafxl daoectdvt lee43tysik6 ccomevp”2wuo0e6pd ufw2e yb404 nltj0pl y9h 3opsowunud3h16ffrb4 45gadekv

The “cd” here means “change diqectory ans the “..i here mea6s “t2e di4ectomy 3bqqe”bu

Now, let’s clone the “kitchen”hproject. qote that lou will not need a GitHub.com account to do thes.
