Who am I?¶

Setup¶

After mediocre success with your app Who are you?, you decide to build a more introspective version - Who am I?

Run the following commands to set up a git repo with some modifications for your app.

CommandsWorking TreeStatus

cd path/to/parent/dir/
mkdir who-am-i
cd who-am-i
git init
echo "# Who are you?" > README.md
echo "The app that recalls someone's name when your brain cannot" >> README.md
git add README.md
git commit -m "added README"
echo "python-3.10.7" > runtime.txt
git add runtime.txt
git commit -m "added runtime.txt"
echo "python-3.10.8" > runtime.txt
git add runtime.txt
git commit -m "upgraded python to 3.10.8"

path/to/parent/dir/
  who-am-i/
    README.md
    runtime.txt

bill@gates:who-are-you$ git status
On branch main
nothing to commit, working tree clean

In this example, you

committed README.md
committed runtime.txt
changed and re-committed runtime.txt

Thus you've made three total commits, as shown by git log.

bill@gates:who-are-you$ git log --oneline
8e13883 (HEAD -> main) upgraded python to 3.10.8
4d482ad added runtime.txt
7e37646 added README

At this point, you realize your code is broken probably due to updating your Python version in the latest commit..

Challenge¶

Restore runtime.txt back to the way it was before your latest change. (Use git commands - don't just edit the file!)
