Squashing PRs

So we did a weird thing (squash commits on main), now let's do the common thing: squash all the commits on a feature branch for a pull request. If your team prefers single-commit-pull-requests, this will likely be your workflow:

Create a new branch off of main.
Go about your work on the feature branch making commits as you go.
When you're ready to get your code into main, squash all your commits into a single commit.
Push your branch to the remote repository.
Open a pull request from the feature branch into main.
Merge the pull request once it's approved.

Assignment

First, let's just do points 1 & 2. MegaCorp needs you to add a new feature to the content management system. Specifically, they need a script that will automatically scan for sensitive information in the repo.

Create a new branch called add_scanner off of main.
In the scripts directory, there is a file called scan.sh. Replace the TODO comment with the following code:

printf "\n====== SCANNING FOR CREDIT CARD NUMBERS ======\n"
grep -rE --color=always '(\b[0-9]{4}[- ]?){3}[0-9]{4}\b' . --exclude-dir={.git} --line-number
echo "========= CREDIT CARD SCAN COMPLETE =========="

Run it from the root of the repo:

./scripts/scan.sh

It should find some credit card numbers in the customers/unstructured.txt file!

Commit your changes with a message starting with K:.
Add another few lines to the end of the script to scan for social security numbers:

printf "\n==== SCANNING FOR SOCIAL SECURITY NUMBERS ====\n"
grep -rE --color=always '\b[0-9]{3}-[0-9]{2}-[0-9]{4}\b' . --exclude-dir={.git} --line-number
echo "======= SOCIAL SECURITY SCAN COMPLETE ========"

Run the script again to ensure it works, and then commit your changes with a message starting with L:.
Finally, add a scan for phone numbers:

printf "\n========= SCANNING FOR PHONE NUMBERS =========\n"
grep -rE --color=always '\b[0-9]{3}-[0-9]{3}-[0-9]{4}\b' . --exclude-dir={.git} --line-number
grep -rE --color=always '\([0-9]{3}\) [0-9]{3}-[0-9]{4}' . --exclude-dir={.git} --line-number
echo "========= PHONE NUMBER SCAN COMPLETE ========="

Run the script one last time to ensure it works, and then commit your changes with a message starting with M:.

Run and submit the CLI tests.
