I've been trying to learn some Bash, and practicing if and then statements by writing a few newbie scripts but I keep getting syntax errors on almost everything I try.

I did a version check on Bash and found out that it's version 3.00 and that might explain why it's not responding to some of my bash commands.

Can Bash be updated? Or is there a workaround?

Sure (PPM). While an example error would've helped, you probably want coreutils. Check if it's installed..

Coreutils is actually installed.

...and the example isn't very long. Just a little joke bash script I tried writing.

#!/bin/bash
clear
echo 'Say Please'
read word

clear
if [ ${word,,} = "please" ]
then
echo 'Thank you.'
fi

In that instance, line 7 ${word,,} comes up as a bad substitution error.

I couldn't understand why. And then I guessed that maybe the version of Bash is too old.

I doubt the bash version's your problem. It's understanding, and you need help.

Saying you run frugal, I suppose you could <IF you really needed to> upgrade..

I'm still getting strange errors.

Does puppy even come with tr? I heard that some stripped down systems don't come with it.

edit: Nevermind. It works. Thank you very much for the help.
