shell script to conditionally add apt repository

rated 0 times [ 5] [ 0] / answers: 1 / hits: 4961 / 2 Years ago, thu, may 12, 2022, 7:01:48

I want to write a shell script that will add an apt repository.

I know that I can do it using sudo add-apt-repository -y <repo>.

My question is can I do it only if the repository was not added already, something like:

if repo was not added yet:

  sudo add-apt-repository -y <repo>

  sudo apt-get update

Thanks

I ended up writing a function to deal with ppa repositories.

add_ppa() {

  grep -h "^deb.*$1" /etc/apt/sources.list.d/* > /dev/null 2>&1

  if [ $? -ne 0 ]

  then

    echo "Adding ppa:$1"

    sudo add-apt-repository -y ppa:$1

    return 0

  fi



  echo "ppa:$1 already exists"

  return 1

}

I wonder if there is some more elegant way.
