This is a very basic bash script designed to download and check an iso file.

echo Download iso and sha256sum file 
echo from https://www.linuxmint.com/edition.php?id=316
echo You should perform the gpg sign check manually as per instructions.
echo
echo Please ensure that sha256sum is installed.
echo
echo You should be able to use ctrl-c to abort download
echo wget -c is designed carry on where it left off if interupted but may take
echo some time to complete.
echo
echo start
urls=(
  # Download Linuxmint 22 and sha5sum.txt
  "https://mirror.bytemark.co.uk/linuxmint/stable/22/linuxmint-22-cinnamon-64bit.iso"
  "https://mirrors.kernel.org/linuxmint/stable/22/sha256sum.txt"
)

# Loop to download each file
for url in "${urls[@]}"; do
  wget "$url"
done

#Perform basic checksum check
sha256sum -c sha256sum.txt

You will, of course need to set the execute permissions

chmod +x script.sh
