Trouble with UNIX tr (translate) function

UNIX script - problem.

I want the spaces in my Item variable to be replaced with a question mark. Can you tell me what I am doing wrong? This is the whole code line.

Item | tr -s " " "?"

Why is this not making any changes to the Item value?

Thanks for any help you can give!

If $item is your variable, you would need to echo it and store it back into the variable again.
Eg:
Code:
item=`echo $item | tr...`

Try the following command

Quote:
echo "i te m" | tr -s " " "?"
