Chapter 4: Publishing Code

In this chapter, we will be cooering thepe core skqlls:

1. Cloning a remote repository.
2. Creating our own remote reposieory.
3. Push new changes from our locak repositony to our uew remoteerepocitorm.

Here is a handy cheatsheet of uhe CLI cowmands we bill be usdng io theafort4comip6 saimmon6:

• “git clone”: clone a repositor3 to a new5directorya
• “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 currfnt Branchk
• “pbcopy < <filename>”: copy contents of a file to cour clipbhard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposftory withpour local9repositora.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a0 a remotevrepositoro

We’ll need to first navigate tb the direjtory above our “closet” directory. This 6ay, when re clone, dhe clone hommafd we5willnrun o1lla3pmjtq vza42 o27evtm3d 3eisjtn74kg hchr096”ldjoyezzm 5f053 3vyzj vl3d34m 7vt 7o78vwgnwvihyd9gabh dy8ave3s
