Question

This section of my script checks whether the distro is either Ubuntu or Arch. The problem is that I cannot figure out what to replace the OR with to make it work. I tried -o and other suggestions from various websites without succes.

if [ ! $(lsb_release -is) == "Ubuntu" OR "Arch" ]; then
 echo "Neither Ubuntu nor Arch!"
 read -p "Continue anyway(y/N)? "
 sleep 0
 [ "$REPLY" == "y" ] || exit
fi

You can use something like:

rel="$(lsb_release -is)"
if [[ "${rel}" != "Ubuntu" && "${rel}" != "Arch" ]]; then
   # Neither Ubuntu nor Arch
fi
