How to check if PPA is already added in a bash script

[alfredino]

Hi,
I found a solution on how to check if PPA is already added to apt sources list in a bash script.
The code worked fine until the previous version of ubuntu 22.04. Now I noticed that the file /etc/apt/sources.list has been moved to /etc/apt/sources.list.d/ubuntu.sources.
Moreover, the "format" of the file has been changed (it no longer contains the deb prefix for some PPAs).
"Old"

deb [arch=amd64 signed-by=file.gpg] URL stable main

"New"

Types: deb
URIs: URL
Suites: noble
Components: main
Signed-By:

I then modified the code accordingly by removing ^.deb and it works fine. Is this correct? Or is there a better way to achieve this?

myPPA=
if ! grep -q ".*$myPPA" /etc/apt/sources.list.d/*; then
     add-apt-repository ppa:$myPPA -y
fi

Thank you
