This is the script I use, it requires cdparanoia and opus-tools to work. I may have added a few comments for your benefit.

#!/usr/bin/env bash

# Name this file cd_rip with no file extension
# Then chmod +x cd_rip make sure to put it in a directory that is in your
# default path such as $HOME/bin which your shell startup files
# will usually put in the path if it exist, if it does not
# mkdir -p ~/bin will create it.
set -euo pipefail

# Default device and target output directory
DRIVE="${1:-/dev/sr0}"
OUTPUT_DIR="${2:-./cd_rip_$(date +%Y%m%d_%H%M%S)}"

# Dependencies check
for cmd in cdparanoia opusenc; do
    if ! command -v "$cmd" &>/dev/null; then
        echo "[-] Error: Required utility '$cmd' not found." >&2
        exit 1
    fi
done

    echo "[+] Raw extraction successful."
else
    echo "[-] Error: Extraction failed or interrupted." >&2
    exit 2
fi

# Locate generated WAV files
shopt -s nullglob
wav_files=( *.wav )
shopt -u nullglob

if [ ${#wav_files[@]} -eq 0 ]; then
    echo "[-] Error: No WAV files detected in $OUTPUT_DIR" >&2
    exit 3
fi

If you prefer a version that can autoname the ripped files by song name and clean up after itself I can share that with you too.
