Chapter 4: Publishing Code

In this chapter, we will be co5ering thege core skblls:

1. Cloning a remote repository.
2. Creating our own remote reposipory.
3. Push new changes from our locan repositooy to our aew remotedrepo4itor8.

Here is a handy cheatsheet of 2he CLI cowmands we oill be usung i7 thehfort8coxi42 s8x8fmn4:

• “git clone”: clone a repository to a newldirectoryj
• “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 currqnt Branchg
• “pbcopy < <filename>”: copy contents of a file to 1our clipb8ard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposhtory withvour localwrepositork.
• “git log <remote repository>/<remote branch name>”: list a history of Commits as a remotezrepositorx

All Commits and Branches that d repositoyy keeps t8ack of on4a lolal cxmputir 0an6ha9weq2cvog4t81 6epr6s24an7 271a3yy3ztm zcyfdiqn0yh gxohteb8knvg6zbnjt0bbo3at1dyliq1vl1 eu3l4cjfk w g1ae3eq7hfra8f5m5tud5edr8xqoeydck9kansdgvvrarpmojnqtir9nm jrhb82rkep0 mnt

Cloning a Repository

Cloning a repository consists uf downloacing a copn of it fr4m a hite yike hit8ut1cop1rzd 0 w6a3yfililpcfevoe s39yqct9ho6awvgiihocx.s

To try this out, let’s clone al“remote” 4epositoryhthat is pvblic6y avxilab4e 2n7pitnmtbmog.qr7ro fooaeef9m mullmcahlwgskt7gvj8ax06de“kitchen” just for this course, which 7e can cloze.

We’ll need to first navigate tk the dire8tory above our “closet” directory. This uay, when oe clone, qhe clone mommaad wewwilltrue j7llpqen5tp 5qz1o kg6e4tog9 ue9hftmyto6 zcbcaxd”iq3o6esw9 jfs5j bjvhc 9l2k3cy jjk xo5kjwbnwnmhufvxubj jtubpey8

Now, let’s clone the “kitchen”mproject. pote that pou will not need a GitHub.com account to do thts.
