Gitignore Exercises

Exercise 1

• Change directories into your home directory
• Make a new directory called git_practice
• Initialize this as a repo
• Use VS Code to make new file called .gitignore (code .gitignore)
• git status from your terminal to see what's red/green
• git add .gitignore
• git commit -m "Add empty gitignore"
• Use VS Code to make new file called secrets.txt (code secrets.txt)
  • add a pretend username and pretend password
• git status from your terminal to see what's red/green
• Open up .gitignore and add secrets.txt as its own line.
  • So, the only line of text is secrets.txt
  • git add .gitignore
  • git commit -m "add secrets.txt to gitignore"
• git status to see what's red/green and the state of things
• Try to git add secrets.txt
• Make a repo on https://github.com/new called git_practice
• Add this remote to your local repo
• git push your work.

Exercise 2

• From your ~/git_practice directory, open up your .gitignore file
• Add the line more_secrets.txt to your .gitignore file
• Run git status
• Now use VS Code to create a file called more_secrets.txt
• Now do git add .gitignore and git commit -m "add more_secrets to gitignore"
• Run git status to see the state of things
• Now push your commit and check your repo on GitHub. What happed? What do you see?

Exercise 3

• Run code ~/.gitignore_global to open up your global gitignore file. Add the following lines:
  env.py
  .DS_Store
  .ipynb_checkpoints/
  pycache
  .vscode/

• Next, run git config --global core.excludesfile ~/.gitignore_global from your terminal

Now it's time to confirm that Exercise 3 is done.

• cd ~/git_practice
• code env.py to create an env.py.
• Inside of env.py, add the following lines
  host = "example_host_ip"
  username = "example_username"
  password = "example_password"
• Save/exit VS code.
• Now do git status
• Do you see that git is tracking your env.py file?
• If it's showing in git status, why is that the case? Double check any spelling in the filename and your global gitignore.
