So I have my program and I cannot figure out how to make the program loop back to the start. I have more of a program however this is the part where I would like the program to restart if I picked yes exit 0 and exit 1 are placeholders at the moment since I do not know how to make it loop. Thank you for your help in advance.

echo "Is that all sir? (Yes/No)"



if [ $word = "Yes" ] 

then exit 0



if [ $word = "No" ]

then exit 1

response=no

while [[ "$response" != "yes" ]]

do

    echo "Is that all? (Yes/No)"

    read -r response

done

References and advice:

The while command and the read builtin in the GNU Bash Reference Manual.

in general, prefer [[ to [ (although it does not matter much in this specific case, it's a good habit unless you need specifically [)

same goes for quoting variable expansion (more discussion here)
