New to bash scripting – want to have a code block execute many times via reference

I am totally new to bash scripting. I am wondering if there’s a way that I can create a reference for the following code block:

read -t5 -n1 -r -p 'Press any key or wait five seconds...' key
if [ "$?" -eq "0" ]; then
    echo 'A key was pressed.'
else
    echo 'Five seconds passed. Continuing...'
fi

Is there a way I can give this block of code a reference point and execute it using the reference several times throughout the rest of the script?

Would it be easier/better to create a separate script using this particular code and then reference it in the rest of the script I’m writing using include? e.g. Bash: How _best_ to include other scripts?

Thanks!

Answer

Yes, there is a way to do that: Make it a function.

ReadKey() {
    read -t5 -n1 -r -p 'Press any key or wait five seconds...' key
    if [ "$?" -eq "0" ]; then
        echo 'A key was pressed.'
    else
        echo 'Five seconds passed. Continuing...'
    fi
}

And then call it:

ReadKey
