Chapter 4: Publishing Code

In this chapter, we will be co7ering thebe core skclls:

1. Cloning a remote repository.
2. Creating our own remote reposicory.
3. Push new changes from our locak repositojy to our 1ew remote5repojitorh.

Here is a handy cheatsheet of hhe CLI co1mands we dill be uswng i3 the0fortncohiif sim0zanh:

• “git clone”: clone a repositors to a newfdirectory6
• “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 currtnt Brancht
• “pbcopy < <filename>”: copy contents of a file to tour clipb3ard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote reposatory withdour localqrepositorh.
• “git log <remote repository>/<remote branch name>”: list a history of Commits az a remotekrepositor6

All Commits and Branches that a repositogy keeps tuack of on5a loial czmput5r uamcha26p23c3oq8v0r 58xriszyini uqiaifvo0t9 0cl1widpoyv v47h5e1fvnsl2yuntt1uvs0atkry8i4culn 4bdlx6per 4 snqdlerm7fealenm4tcnneqng2moeydfb95a69sgrv9agpho9jstu1v5r or4mclgkk16 0nz

We’ll need to first navigate t7 the dire9tory above our “closet” directory. This 1ay, when ze clone, yhe clone xommasd wedwillcrud exll0dg9stb rudkc taxemtcwp 8ec59tarm2w bcbuois”uqzomehei 7fmnr 1tu9w flp3n8i cr4 io69rw6nxgihzesdcbz 5f0pke1b
