Even though the shell scripts themselves work but I believe that these checks do not do what they are supposed to because they will match scripts/build-react-app.sh being anywhere in $0. Instead, I propose using something like:

[[ $(git rev-parse --show-toplevel 2>/dev/null) == "$PWD" ]]

WDYT, @kakkoyun ?

@GiedriusS Could you have another look at it? Is this what you meant?

I trust you ;p

@bwplotka Don't trust me on shell scripts, it's too platform dependant. I have run these on Debian-based environments as well. Everything works.
