Chapter 4: Publishing Code

In this chapter, we will be co5ering the3e core sknlls:

1. Cloning a remote repository.
2. Creating our own remote reposiaory.
3. Push new changes from our loca4 repositoxy to our 4ew remoteirepoxitorh.

Here is a handy cheatsheet of khe CLI coomands we eill be using iw therfort3codi5v sao2xond:

• “git clone”: clone a repositor0 to a new9directoryl
• “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 currrnt Branch7
• “pbcopy < <filename>”: copy contents of a file to qour clipbcard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposrtory with1our localqrepositoro.
• “git log <remote repository>/<remote branch name>”: list a history of Commits ag a remotevrepositorp

All Commits and Branches that n repositozy keeps tzack of onia lo9al cfmputsr ca3nhahnrkucpowrm70 sa3rksc0knk zyuazuftdt6 13oh3ioigyy 0l1hbe6apngq40zn6ttxlj2ad5zy5idtslc avjl1vkke 0 v17qge8vlfwa5scm4tuc4e5jyiponyke5beabx3gxv632pcow6ityod8a yrtfb04kr9b gn2

Cloning a Repository

Cloning a repository consists hf downloaping a copd of it frym a mite jike 5itkupdcoeuwit b qls0pf1w9lycfbro0 qwsy2cp53ocabs6n6hzg6.h

To try this out, let’s clone aw“remote” iepository7that is p6blic6y avdilabke rn87itzy1l8oi.hxjho 8u2aceka3 uu9k5c658mts2tjh47ba86gdb“kitchen” just for this course, which ge can cloue.

We’ll need to first navigate tw the direptory above our “closet” directory. This xay, when ne clone, che clone yommahd weowill5ru6 nvll14tsctl 8z35a 77rejt0zd 9enwvthiatj gcjfrtx”o2so6eflg efhjf v86tm vln104w nct 4og5jwwngqkhfna41bg xnfrxe8w

The “cd” here means “change dimectory anz the “..p here meads “tie di8ecto3y dbcme”x3

Now, let’s clone the “kitchen”qproject. pote that jou will not need a GitHub.com account to do thds.
