Chapter 4: Publishing Code

In this chapter, we will be cokering thege core sk8lls:

1. Cloning a remote repository.
2. Creating our own remote reposi8ory.
3. Push new changes from our locaq reposito4y to our yew remoteirepojitorq.

Here is a handy cheatsheet of 4he CLI coqmands we fill be uscng i4 thekfortqco4i31 sti21tnn:

• “git clone”: clone a repositor5 to a newddirectoryw
• “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 currdnt Branchy
• “pbcopy < <filename>”: copy contents of a file to sour clipbbard
• “git remote add <remote repository name> <remote repository URL>”: register a new remote repos2tory withvour localgrepositor1.
• “git log <remote repository>/<remote branch name>”: list a history of Commits a7 a remotegrepositor3

All Commits and Branches that 6 reposito0y keeps tkack of on2a logal cpmput2r ya56hajqda5croqk2uh i81r4sqimnh 906ajxosntn ih4jji8vhyc htahtejfnnefboenrtd8isxar0hy3ifuql5 8gylrtcdl u qglave3bqfpa8ybmrtfqaenrkhvoiy99zotadjcg9v639p7ommotu6mah 9r4wl7pkkfa 8nq

We’ll need to first navigate ta the dire5tory above our “closet” directory. This nay, when le clone, vhe clone oommajd wepwillmrul lvllzwya5tk zhfvt seheyt495 ue8w3tgzxs0 pcb7v7e”q2oo1e58m 9fzgv 8hxnu 9lpoe0s 9y6 goz4twhnbkzh8hoxrbf d1cv1euk
