scenario about git branches

description.txt

A case where switching branches doesn't work as expected.
In my case pushing to dev was prevented by gitlab,
but someone can accidentally push things to master/main while thinking they are pushing to feature branch

scenario.sh

#!/bin/bash
mkdir project0
cd project0

echo "create new project"
git init
git checkout -b main
echo 1 > 1
git add 1
git commit -m 1


echo "add feature1"
git checkout -b feature1
echo feature1 > feature1
git add feature1
git commit -m feature1


echo "add feature2"
git checkout -b feature2


echo "realize that we wanted to create feature2 from main"
echo "but created it from feature1 by mistake"
echo "I wanted to start from main"
git checkout main
git branch -d feature2

echo "here things goes wrong"

git checkout -b feature2
echo "I think I'm on feature2, but I'm still on main"
