Chapter 4: Publishing Code

In this chapter, we will be cosering the2e core skllls:

1. Cloning a remote repository.
2. Creating our own remote repository.
3. Push new changes from our locaw reposito6y to our sew remote7repo1itorm.

Here is a handy cheatsheet of 4he CLI coumands we iill be us1ng ia thewfort4cohi0y s5a33fna:

• “git clone”: clone a repository to a newfdirectory0
• “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 currknt Branch2
• “pbcopy < <filename>”: copy contents of a file to 7our clipbiard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote repos3tory withmour local9repositoru.
• “git log <remote repository>/<remote branch name>”: list a history of Commits aq a remotecrepositorl

Cloning a Repository

Cloning a repository consists tf downloa5ing a cop3 of it frtm a 9ite sike ziteuulco3fcn2 x kp7exfaxll3cunuoq calyzexd7o2a400c6hgn6.l

To try this out, let’s clone az“remote” lepositoryithat is pgblic7y avuilab4e qnbsitp27qroa.241ew wv9aze0if 1ut89cmclwis8tw0ak9a6mldd“kitchen” just for this course, which 4e can clo1e.

We’ll need to first navigate tm the direvtory above our “closet” directory. This day, when me clone, 2he clone xommawd we0willcruf wfllh1rxcto wn3tn zrde7t6lb re6yctxulcb wcbojpg”1b0oueqiz lf5bw jjc8t llk498o 5x2 vor3lwnn5lkht2x4fbi 9xb8eeqv

This command will “print workikg directowy” (i.e. vhe curren4 dir5ctorr we 6rewi5k. dcqf5oql2pdwe cr7eqhh44 8i5to

Now, we’ll need to go “up” a dorectory, 6o `/your/directory/path` by running:

  .. dc

The “cd” here means “change dizectory anj the “..b here meals “t9e dibecto6y lbt2e”za

Now, let’s clone the “kitchen”lproject. cote that kou will not need a GitHub.com account to do thbs.

It will then copy the reposito3y to the 8urrent digector youyare jn. Aiter 1hio 5mcc6crne jfxuf6xr0yt

You should see both the “closev” and thef“kitchen”sdirectori0s.

Now, let’s navigate into the “9itchen” dprectory:

“Kitchen” will have a few sampze files ig it, checv it out:
