Help with String Comparison

I'm running the following script to compare string values to a regexp:

Code:

for entry in $(lpinfo -v | cut -c 1-); do
    if [$entry == socket://*]
      then
        echo "blah"
      continue
    fi
done

What happens when you do this:

Code:

if [ "$entry" = "socket://*" ]

Yep, that did it. I didn't know you had to have a space between the brackets and the operations on the inside. Also, I had to do a double bracket test to make the evaluation interpret the right side as a regexp. So:

Code:

if [[ $entry == socket://* ]]
